My Next Twelve Months, Month by Month

The question almost always arrives with two dates already in it. From today until the end of December. From now until my birthday. The next twelve months. People are not asking for a general reading; they are asking what happens inside a window they have already drawn, and they want the answer laid out in order, with dates on it.

A twelve-month forecast is built from two clocks running at once, and the whole difficulty of the format is that the two do not tick together. The first clock is the sky, which is the same sky for everyone alive. Jupiter changes sign on one date and it is that date for every reader of this page. The second clock is your own ladder of planetary periods, which is computed from where the Moon stood at the moment you were born and therefore belongs to you and to almost nobody else. The sky says when something is available. The ladder says whether you are the person it is available to.

The first clock is published below in full, with every date, because it is knowable in advance and there is no reason to hold it back. Everything quoted here is sidereal, meaning positions measured against the fixed stars using the Lahiri ayanamsa, which is the offset between the two zodiacs and the standard Indian practice. Every date is a computed instant in Indian Standard Time.

The measurement that decides how this page is built

Your chart does not produce twelve rows. It produces an uneven ladder of dated segments, and for most people that ladder has about five edges in a year rather than eleven.

The window used throughout this page is 26 August 2026 to 25 August 2027. 100,000 charts were computed for people born between 1975 and 2005 in ten Indian cities, at a uniformly random clock minute, and each one's ladder of periods was read across those 365 days.

Over twelve monthsMedianRange
Dated period boundaries in the window51 to 23
Calendar months containing no boundary at all7 of 120 to 11
Calendar months containing two or more00 to 9
Share of the year held by the single longest period35%8% to 55%
Days until your first boundary from 26 August360 to 201

The second row is the one to read twice. For half of all charts, seven of the next twelve calendar months contain no dated turning point whatsoever. The chart has nothing new to say in those months. A forecast that prints a fresh theme against each of them has written seven paragraphs the chart did not ask for, and a reader who takes those seven seriously is acting on invention.

So what should the honest version look like? Keep the twelve rows, because the calendar month is the unit you live in and it is the unit you asked the question in. Then let rows repeat. A month is labelled with the period that actually governs it, with that period's real start and end dates, which will almost never be the 1st and the 31st. Five consecutive months carrying the same label is a true statement about the year and a useful one, because it tells you where the long stretch is and therefore where to put anything that needs continuity.

The spread says something the median hides. One person in fourteen has two or fewer boundaries in the whole year, and their twelve months genuinely are one or two chapters. At the other end, 3.9% have fifteen or more, running in segments of eight to thirty days, and for them a monthly grid is too coarse rather than too fine. Both are normal. Which one you are is not a matter of luck; it follows mechanically from which planet rules your period, and the next section shows how.

Two more counts from the same 100,000, because they set expectations for what a year can contain:

  • 59.2% have at least one change of sub-period inside the window, meaning the second of the three layers turns over. For 40.8% it does not, and their year runs entirely inside one sub-period.
  • 7.3% have a change of major period, the top layer, which is the one that changes the subject of a life rather than the emphasis of a year.

The first clock: the sky from 26 August 2026 to 25 August 2027

Sixty-three dated events fall in this window and every one of them is identical for every person reading this. They are worth having in front of you before any personal chart enters the picture, because they are the raw material a twelve-month forecast is decorated with, and most of what you will read elsewhere about "2027" is one of these dates with an adjective attached.

Jupiter moves three times

Jupiter starts the window at 18 degrees of Cancer, moving forward.

DateEvent
31 October 2026Jupiter leaves Cancer and enters Leo
13 December 2026Jupiter turns retrograde
25 January 2027Jupiter returns to Cancer
13 April 2027Jupiter turns direct
26 June 2027Jupiter enters Leo again, and stays

Jupiter crosses the same boundary twice because it reverses in between. It reaches the start of Leo, slows, turns back while still early in the sign, sits in the last degrees of Cancer for five months, then comes forward and crosses for good. Retrograde means the planet appears to move backwards against the stars as seen from Earth, which happens because we are overtaking it in our orbit. In practice it means the affairs of the sign it is leaving get one more pass before they close.

Saturn moves once, and it is the big one

DateEvent
11 December 2026Saturn turns direct in Pisces
3 June 2027Saturn leaves Pisces and enters Aries
9 August 2027Saturn turns retrograde in Aries

Saturn's mean motion carries it once round the zodiac in 29.5 years, so it changes sign about every two and a half years, and a Saturn ingress is the least frequent event on this list. The 3 June 2027 crossing also changes the Saturn-over-Moon reading for eight of the twelve Moon signs on the same day, which is set out further down with the eight named.

Rahu and Ketu move together, once

DateEvent
5 December 2026Rahu leaves Aquarius for Capricorn, and Ketu leaves Leo for Cancer

Rahu and Ketu are the two lunar nodes, the points where the Moon's path crosses the Sun's, and they are always exactly opposite each other and always moving backwards through the zodiac. That is why one date serves for both.

The retrogrades

Mercury10 June 20275 July 2027

Mars also changes sign six times in the window, more than any other planet here, because its retrograde carries it back over ground it had already covered.

The Sun's twelve months

The Sun enters a new sign about every thirty days, and this is the closest thing the tradition has to a calendar month. Each of these dates moves the Sun into the next house of your chart, counted from your rising sign.

The 14 January 2027 entry into Capricorn is Makar Sankranti.

The Moon's twenty-five turns

Twelve new Moons and thirteen full Moons fall in the window. The full Moon of 28 August 2026 opens it and the full Moon of 17 August 2027 closes it. These are the fastest hands on the shared clock, useful for choosing a day inside a month you have already picked, and close to useless for choosing the month.

Placing those dates in your chart takes one fact about you

Sixty-three shared dates are not a forecast. What turns a date into a statement about you is which house it falls in, and the house is decided by your rising sign, meaning the sign that was climbing over the eastern horizon at your birth. This page uses whole-sign houses, where the whole of your rising sign is the 1st house, the whole of the next sign is the 2nd, and so on around, which is the standard Indian method and needs no arithmetic beyond counting.

Ketu is always six houses away from Rahu, so add six and wrap around. If Rahu is in your 9th, Ketu is in your 3rd.

Two readings fall out of this table immediately. Libra rising has Jupiter crossing into the 11th house on 31 October 2026, backing out again on 25 January, and settling there from 26 June 2027, which puts the year's slowest benefic on income and on the people who bring it. Capricorn rising has Rahu arriving in the 1st house on 5 December 2026, which is the node landing on the body and the public self rather than on any department of life. Neither statement needs your birth time. Both need only the rising sign, and the free kundli tool gives you that from your birth date, time and place in one step.

The rising sign also decides whether a planet is working for you or against you, which is a separate question from where it is standing, and a planet can be in a strong house for you while being the one your chart finds difficult.

Saturn over your Moon: what changes on 3 June 2027

Sade sati is the roughly seven-and-a-half-year stretch in which Saturn transits the sign before your Moon's sign, then the sign your Moon itself occupies, then the sign after that. Shani dhaiya, the smaller version, is the roughly two-and-a-half years when Saturn stands in the 4th or the 8th sign from your Moon. Both are read from the Moon, so both need your birth date and, ideally, your birth time; the free rashi tool gives you your Moon sign, and the sade sati tool gives you the phase and the dates.

Saturn leaving Pisces for Aries on 3 June 2027 changes the reading for eight of the twelve Moon signs on the same day, which is more readings than any other date in the shared half of this window changes.

If your Moon is in Aquarius, a seven-and-a-half-year passage closes on 3 June 2027. The next one does not begin for about twenty-two years, since Saturn takes 29.5 years to come round and the passage itself uses 7.5 of them. If your Moon is in Taurus, the same date opens one.

Those two readings are opposite and they come from one event. No forecast written for a general audience can tell you which of them is yours, and that limit applies even here, inside the half of the year everybody shares.

For what the passage actually does, and how common it is at any moment, see how many people are in sade sati right now and the sade sati survival guide.

The second clock: your own ladder of periods

A dasha, meaning a stretch of time handed to one planet, is what the second clock is made of. The system that hands them out is called Vimshottari (the name counts the 120 years of one full cycle), and it divides those 120 years among the nine planets in a fixed order, then gives you your starting point inside that order from the exact position of the Moon at your birth. That is the whole mechanism, and it is worth following because every dated statement in the rest of this page comes out of it.

The zodiac is divided into 27 nakshatras, which are segments of 13 degrees and 20 minutes each, and every nakshatra has a ruling planet. Find the nakshatra your Moon occupied at birth, take its ruler, and that planet's period is the one you were born into. How far through the nakshatra the Moon had already travelled tells you how much of that period was already spent before you drew breath. From there the sequence runs in the same fixed order for everyone: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17.

Each of those major periods, called a mahadasha, is divided into nine sub-periods in the same order and in proportion to the same year counts. Those sub-periods are called antardashas. An antardasha is a section running inside the chapter, and it is divided the same way again into nine pratyantar periods, which is the layer a twelve-month table actually runs on. Three layers are therefore always running at once: the major period is the chapter, the sub-period is the section, and the pratyantar is the paragraph.

Why one person gets two dated edges in a year and another gets seventeen

The lengths follow from arithmetic rather than from anybody's judgement. Each third-layer period is the product of three year counts, so one ruled by long planets inside long planets runs for most of a year and one ruled by short planets inside short planets is over in a week.

Third-layer periods inside aShortestLongest
Sun major period, 6 years5 days61 days
Ketu or Mars major period, 7 years6 days71 days
Moon major period, 10 years9 days101 days
Jupiter major period, 16 years15 days162 days
Mercury major period, 17 years16 days172 days
Rahu major period, 18 years16 days183 days
Saturn major period, 19 years17 days193 days
Venus major period, 20 years18 days203 days

The shortest entry in each row is the one ruled by the Sun at both lower layers and the longest is the one ruled by Venus at both, so which end of the range you are actually sitting at is decided by your sub-period rather than by the chapter you are in. Across the 100,000 charts, the third-layer period running on 26 August 2026 has a median length of 81 days, with a tenth of people under 30 days and a tenth over 164. The shortest computed anywhere in the study was 5 days and the longest was 202.

So the useful first question is not "what does each month hold" but "how many segments does my year have at all, and where do their edges fall". For 47.5% of charts the answer is two, three or four edges. For 3.9% it is fifteen or more.

What makes a period say something specific rather than generic

A period lord on its own is a planet and a mood. Two facts turn it into a statement about your life, and both need your chart rather than your birth year.

The house the period lord occupies. A period run by a planet standing in your 10th house is about your standing and your work. The same planet in your 4th is about home, property and the ground under you. Across the 100,000 charts this is close to perfectly flat: the major-period lord stands in each of the twelve houses between 8.1% and 8.5% of the time. The flatness is the useful part. It means the house your period lord occupies is a genuine one-in-twelve fact about you, with no population-level tilt that a general article could summarise on your behalf.

Whether that lord is working for you. In Parashari practice, a planet's functional nature is decided by which houses it rules from your rising sign. The lord of your 1st, 5th or 9th is a functional benefic. The lord of your 6th or 8th is a functional malefic, the planet whose periods bring the friction. A planet ruling both an angle and a trine at once is the yogakaraka, the strongest single deliverer a chart can have, and there are exactly three of them: Saturn for Taurus and Libra rising, Mars for Cancer and Leo rising, Venus for Capricorn and Aquarius rising.

This is where most general writing about periods goes wrong, and running the lordship rule across all twelve rising signs shows why.

Saturn is a functional benefic for six of the twelve rising signs and a functional malefic for two. So "Saturn's period is a hard period" is wrong for half the population by the tradition's own rule, and for Taurus and Libra rising it is the reverse of the truth: Saturn is their yogakaraka. Jupiter runs the same way in mirror, benefic for six and malefic for Taurus and Libra. Rahu and Ketu rule no sign, so they have no functional nature at all and are read entirely from where they stand and what they touch.

Across the 100,000 charts, the planet running the major period is a functional benefic for 36.1% of people, a functional malefic for 12.9%, and functionally neutral for 51.0%. Half of everyone is living through a chapter run by a planet that is neither for them nor against them, which is not a disappointing answer. It means the house and the sub-period are carrying the reading, and the headline planet is not.

One more count worth having: for 13.3% of people at any moment the major period and the sub-period belong to the same planet. That is the loudest configuration the system produces, one planet holding two of the three layers, and it is the case where a single planet's themes really do describe a year.

Four charts, worked all the way through

These are four charts drawn from the same synthetic population, chosen to cover the range rather than to flatter it. Every date, house and period below is computed. You can reproduce any of them from the birth details given, using the free dasha calculator and the free kundli tool.

One: two edges in the whole year, and the sky supplies the third

13 October 1976, 15:14, Mumbai. Aquarius rising, Moon in Taurus in Rohini.

Saturn major period. Saturn rules the 1st and the 12th house from Aquarius, and the 1st is one of the three houses whose lord counts as a functional benefic, so Saturn is working for this chart. It stands in the 6th house, and Venus, not Saturn, is the yogakaraka for Aquarius rising.

PeriodFromToDaysLord's house
Saturn / Venus / Jupiter31 May 20261 Nov 20261544th
Saturn / Venus / Saturn1 Nov 20264 May 20271836th
Saturn / Venus / Mercury4 May 202714 Oct 20271638th

Two dated edges in twelve months, on 31 October 2026 and 4 May 2027, and one of the three blocks runs for six months. A month-by-month table for this chart would be eleven rows of the same sentence. The useful version says: one long stretch to the start of November, then a six-month stretch through the winter run by this chart's own rising-sign ruler standing in the 6th house, then a change in early May.

Now bring in the first clock. This chart's Moon is in Taurus, so 3 June 2027 is the date Saturn arrives in the sign before it and a seven-and-a-half-year passage begins. The ladder has nothing to say in June 2027 and the sky has the year's largest thing to say. A forecast built from the periods alone would have printed a quiet June for this chart, and a forecast built from the transits alone would have missed that the same June sits in the middle of a stable six-month period, which is what makes the passage survivable. Across the same 100,000 charts the Moon falls in each of the twelve signs between 8.1% and 8.5% of the time, so roughly one reader in twelve is in this position this year.

Two: five edges, and five months under one period

20 September 1990, 01:53, Mumbai. Gemini rising, Moon in Virgo in Hasta.

Jupiter major period. Jupiter rules the 7th and the 10th from Gemini, so it is functionally neutral here, and it stands in the 2nd house. Saturn runs the sub-period all year.

Jupiter / Saturn / Mars14 Aug 20277 Oct 20275312th

This is the median chart in the study made concrete: five edges, and the block from 9 November to 13 April covers five calendar months on its own. Venus is a functional benefic for Gemini rising and stands in the 3rd house, so that five-month stretch is the year's long even run. The last row is the one to diarise: Mars is the functional malefic for Gemini rising and it sits in the 12th house, and its turn starts on 14 August 2027.

This chart's Moon is in Virgo, which means Saturn arriving in Aries on 3 June 2027 stands in the 8th sign from it and starts a shani dhaiya. So the sky adds a dated event in a month where the ladder has none, exactly as it did for the first chart, on the same date and for a different reason.

Three: the chapter itself changes inside the window

Mercury / Mercury / Sun30 Jul 202712 Sep 2027438th

On 10 September 2026 the Saturn major period ends and a seventeen-year Mercury period opens. This happens to 7.3% of people in any given twelve months, and it is the one event in this system that changes the subject rather than the emphasis. Note what the first four months of it look like: Mercury holds all three layers at once, which is the 13.3% configuration, and Mercury is the ruler of this chart's rising sign standing in the 9th house. A year with a top-layer change in it is not a year to plan around a monthly grid at all. The grid to use is before 10 September and after.

Four: seventeen edges, in blocks of eight to thirty days

18 December 1991, 02:47, New Delhi. Libra rising, Moon in Aries in Bharani.

Moon major period until 5 May 2027, then Mars. Seventeen dated edges in the window. The first three and the last three:

From 4 November 2026 the Sun runs the sub-period, and a Sun sub-period inside a Moon major period is six years times ten years divided by 120, which is six months, cut into nine pieces of eight to thirty days each. Then Mars takes over the major period on 5 May 2027 and the same compression continues, because a Mars period is seven years long.

For this chart a monthly forecast is the wrong resolution in the other direction. November 2026 alone contains three different third-layer periods. This chart also has its Moon in Aries, so it is in the rising phase of sade sati at the start of the window and moves to the peak phase on 3 June 2027, which is the same date that released the Aquarius Moons.

What the four show together

Four charts, same twelve months, same sky. Two edges, five edges, four edges with a chapter change in the middle, and seventeen. Three of the four have a Saturn-over-Moon change on 3 June 2027, and each of the three is a different change: one enters sade sati, one enters dhaiya, one moves from the rising phase to the peak. Not one of the four would be described accurately by a twelve-row table with a different theme in each row, and no two of them would be described by the same table at all.

The honest twelve-row table

Here is the Gemini rising chart from example two, laid out the way the question gets asked, with both clocks in the same grid. The period column repeats where the period repeats, which is the point.

One period, Jupiter / Saturn / Venus, governs the whole of December, January, February and March and most of November and April. Seven of the twelve months contain no personal edge at all, which is exactly the median from the first table. The three bold entries are the slow structural moves: Jupiter into the 3rd house, the two nodes into the 2nd and the 8th, and Saturn into the 11th.

Read as a whole, the table says something a list of monthly themes cannot. The year's continuity sits between 9 November and 13 April, so that is where a long piece of work belongs. Its personal turns are 9 November, 13 April, 29 May and 14 August. And one shared date, 3 June 2027, lands three weeks into a fresh personal period and starts a two-and-a-half-year Saturn passage over the Moon, which makes that week the most loaded in the twelve months for this chart. None of those three statements survives dropping either clock.

The birth-time measurement, and why this page will not guess yours

Everything above rests on the position of the Moon at your birth, and the Moon is the fastest body in the chart. That has a consequence which is easy to state and easy to measure, and it is rarely stated.

Your starting point in the 120-year cycle is set by how far through its nakshatra the Moon had already travelled, so a one-minute error in your recorded time does not move your dates by a minute. It moves them by that same fraction of a whole period. The Moon crosses one nakshatra in about 24 hours and 20 minutes, so a minute is roughly one 1,458th of the crossing. Applied to a twenty-year Venus period, one 1,458th is five days. Applied to a six-year Sun period it is a day and a half.

5,000 charts were computed twice, once at their recorded minute and once at a known offset, and the entire ladder was compared.

Error in the recorded birth timeEvery date in the table slides by (median)
1 minute3.9 days
4 minutes15.5 days
10 minutes38.6 days
30 minutes115.6 days

The rate is exact and you can compute your own. It is set by the ruler of the nakshatra your Moon occupied at birth, because that ruler's period is the one whose remaining portion your whole ladder hangs from. One minute of birth time moves every subsequent date by 1.5 days if that ruler is the Sun, 1.8 days for Ketu or Mars, 2.5 for the Moon, 4.0 for Jupiter, 4.3 for Mercury, 4.5 for Rahu, 4.8 for Saturn, and 5.0 days if it is Venus.

Two more results from the same test put that in proportion:

  • At 15 minutes of error, the rising sign changes for 12.3% of charts and holds for the other 87.7%. At the same 15 minutes, the third-layer period you are currently running changes for 59.5%.
  • At 30 minutes of error, the Moon crosses into a different nakshatra for 2.0% of charts, and for those people the entire sequence of period lords is different, not merely shifted. Every planet in every row changes.

And the number that makes the point: the 63 shared sky dates move by exactly zero. Jupiter enters Leo on 31 October 2026 whether or not anybody knows what time you were born.

So the dated ladder is more sensitive to your birth minute than the rising sign everyone worries about. That is a reason to state the sensitivity next to the dates rather than a reason to avoid dates, and the next section is how to work with an approximate time rather than around it.

If your birth time is approximate

Most people's recorded time is rounded to the nearest five or ten minutes, and plenty of Indian birth certificates round to the quarter hour. Three practical moves follow from the table above.

Treat the dates as centres, not edges. If your time is good to five minutes, your boundaries are good to about three weeks either side. Plan the month, not the day.

Run the calculator three times. Enter your recorded time, then ten minutes earlier, then ten minutes later, on the free dasha calculator. If the boundary you care about moves by a fortnight, plan for a fortnight. If your Moon changes nakshatra across those three runs, the answer is that your ladder is not yet settled and the birth time needs checking against a document before anything else is worth doing.

Check the nakshatra before anything else. If your Moon was near the end of one nakshatra, a twenty-minute correction changes which planet rules your whole life sequence, and no amount of care about the dates matters until that is settled. The kundli tool prints the Moon's degree inside its nakshatra, so you can see how close to an edge you are in one look.

For the wider question of how much of a reading depends on birth time at all, what is Vimshottari dasha covers the mechanism and what is my current mahadasha covers the first layer.

Reading the two clocks together

The method is one sentence: the sky says when a door is open for everybody, and your ladder says whether you are standing next to it. Four rules make that usable.

A shared date only counts if it lands somewhere that matters in your chart. Jupiter entering Leo on 31 October 2026 is a 3rd house event for Gemini rising and an 11th house event for Libra rising, and those are different years. Use the rising-sign table above before you read anything else about that date.

A shared date counts double if its planet is also running your period. If Saturn is your major-period or sub-period lord, then 11 December 2026 and 3 June 2027 are your dates in a way they are not for anybody else, and if Jupiter is, the three crossings are. This overlap is the most useful thing the two clocks produce together, which is why the twelve-row table above puts both in one grid.

Put anything needing continuity inside your longest block. Half of all charts have one period covering 35% of the year or more. Long projects, negotiations that take months, anything with a slow build, belong there rather than straddling a boundary.

Put decisions near a boundary, not across one. Where a boundary falls, the conditions you were planning under change. The useful move is usually to finish inside the current period and start the new thing after the edge rather than three weeks before it.

None of this names events. The two clocks give you dated windows and the parts of life those windows touch, and what arrives inside a window still depends on what you put into it. A period that supports work supports work you are doing.

Compute your own, free

The shared half of this page is above with every date in it. For your own half, these tools need no account and no payment.

  • Kundli gives your rising sign, your Moon's nakshatra and degree, and every planet's house, which is everything the tables above ask for.
  • Dasha calculator gives the three periods you are running right now with their dates, and the major periods that come next.
  • Rashi gives your Moon sign, which is what the sade sati table is read from.
  • Sade sati gives your phase and the dates it changes, including whether 3 June 2027 is one of yours.
  • Hard years marks the stretches the chart reads as demanding, which is useful for placing effort rather than avoiding it.
  • Career timing reads the same two clocks for work specifically, and gives the next dated turning point.

Where to get your own ladder, and what each thing actually carries

The method is published above in full, including the measurement that says a twelve-row table with twelve different themes is mostly invention. Here is what each part of the site computes for you, stated exactly, because the resolutions differ and picking the wrong one is a waste of your money.

  • Chart Chat is given your dated ladder before it answers anything: every sub-period of your current major period with its start and end dates, every third-layer period inside your current sub-period with its dates, and the major period that follows. Ask it for the ladder between two dates and it is reading, not estimating. This is the closest thing to the tables in the worked examples above, and it is where the questions behind this page came from.
  • The month-ahead reading carries the third-layer segments dated and clipped to a thirty-day window, with each day of the window scored from your birth star, and the strong and guarded days listed rather than summarised. It is the right instrument when your question has a date inside the next month.
  • The year-ahead reading works at a coarser resolution on purpose: your running major period and sub-period with dates, the Jupiter and Saturn tracks across the year including the houses they change into and when, your sade sati or dhaiya phase with the years left on it, how far Jupiter is from returning to its birth position, and twelve dated monthly rows. It is the year's shape and its structural dates rather than the third-layer ladder.
  • The free dasha calculator gives the three periods running today with their dates and the major periods that follow, which is enough to place yourself on the ladder and to run the birth-time check described above.

The one thing none of them does is name events. Every one of them gives dated windows, the houses those windows touch, and whether the planet running them is constructive for your rising sign.

Common questions

"From today until 31 December, how will my career progress?"
That window is 127 days from the date this page was computed, and the honest first step is to find out how many dated edges your chart puts inside it. Measured over the same 100,000 charts for exactly that stretch, 26 August to 31 December 2026, the median is two edges and the mean is 2.11; 36.3% of charts have exactly one, and 6.0% have none at all. Where you have none, the answer for the whole window is one period, and the useful reading is which house its lord occupies rather than a month-by-month breakdown that would be the same paragraph four times. Where the window does contain an edge, that date is the answer to "when", and career timing gives it free.
"Give me a month-wise breakup with proper dates."?
The dates exist and this page shows exactly what they look like. What will not be true of the result is twelve different months. Expect between two and eight boundaries across the year, three, four or five for half of all charts, sitting at uneven distances, with several months carrying no boundary at all. A table with the real dates in it is more useful than a tidy one, and considerably shorter.
"Which is more important, my dasha or the transits?"
They answer different questions and the comparison is a trap. The shared sky tells you what is available and when, down to the minute, for everyone. Your ladder tells you which of it reaches you. The place they meet is the useful reading: a shared date whose planet is also running your period, landing in a house that matters in your chart.
"Does my birth time really matter this much?"
For this question, more than for any other on the site. One minute moves every date by about four days. Your rising sign, by contrast, survives a fifteen-minute error 87.7% of the time. A chart read without an exact time still answers plenty of questions well. A dated twelve-month table is not one of them.
"Why does everyone else publish twelve different months?"
Because twelve rows is the shape of the question and it looks complete. The measurement in the first section is what happens when you check that shape against the charts: the median person has five edges and seven empty months. Filling the empty ones requires writing something the chart did not produce.
"My Moon is in Aquarius. What actually happens on 3 June 2027?"
Saturn is currently in Pisces, which is the sign after yours, and that is the setting phase, the last of the three. On 3 June it moves on and the seven-and-a-half years close. The reading the sade sati tool gives for the setting phase is that money and family matters are the ones under pressure and that the intensity is already reducing, so the date reads as the end of a release rather than as a shock. Whether it shows up as an event at all depends on your ladder, and on which house Aries occupies in your chart.
"I have fifteen period changes next year. Is something wrong?"
No. It means your major period or your sub-period belongs to a short planet, most often the Sun, Ketu or Mars, so the third layer is cut into pieces of eight to thirty days. It happens to 3.9% of people at any time. The right resolution for a chart like that is the week rather than the month, and the month-ahead reading is built at that resolution.
