Kalachakra Dasha

The wheel of time

Kalachakra — the wheel of time — is the most intricate dasha AstroShruti computes, and the one most often described and least often explained. Its reputation for complexity is earned, but the complexity is all in one place: the lookup. Once you know your sequence, the rest is arithmetic.

It belongs to the rashi dasha family, alongside Chara and Narayana. That is the headline fact and the one to hold onto: its periods are signs, not grahas. Where Vimshottari says “you are in Saturn”, Kalachakra says “you are in Capricorn”, and you go looking for what Capricorn means in your chart — which house it holds, who sits in it, where its lord has gone.

But Kalachakra is the odd member of its own family too. Chara and Narayana are seeded from the Lagna. Kalachakra is seeded from the Moon — and that makes it the one bridge in the whole system between the nakshatra dashas and the sign dashas.

Seeded from the pada, not the nakshatra

Here is the distinction that matters, and it is finer than most write-ups admit.

Vimshottari needs to know which nakshatra your Moon is in, so that it can read off that nakshatra’s lord. Kalachakra needs to know which quarter of which nakshatra — the pada. A nakshatra spans 13°20’; a pada is 3°20’ of it.

That pair — nakshatra and pada — is a lookup key. It selects:

1. Your group. The 27 nakshatras are split between Savya (deasil) and Apasavya (widdershins), each further split into two sub-groups. Four groups in all.
2. Your nine-sign sequence, from the table belonging to your group and pada.
3. Your paramayush — the total span of that sequence.

Move the Moon 3°20’ and every one of those three can change together. This is why Kalachakra is unforgiving about birth time in a way even Vimshottari is not: the Moon crosses a pada in roughly six hours, and crossing one does not shift your dates, it replaces your sequence.

The four groups

Nine, six, four and eight — twenty-seven. The grouping is not a rule you can derive at the table; it is a table, and we ship it as one.

The paramayush

Each pada carries a span:

The same four numbers, mirrored. That mirroring is the wheel turning the other way, and it is the clearest single expression of what Savya and Apasavya mean.

Paramayush is a longevity figure in the tradition — the full span the wheel allots. We use it structurally: it is the cycle length, and it is the denominator against which the balance at birth is measured. We do not print it as a prediction about how long you will live, and neither should anyone reading it.

The years each sign carries

Unlike Chara, Kalachakra’s sign durations are fixed — the same for every chart. What varies is which nine signs your sequence visits, and in what order.

Cancer’s 21 years and Capricorn’s 4 are not a scaling of anything — they are the table. And here is the elegant part: the nine signs of your pada’s sequence sum exactly to your paramayush. Savya pada 1 runs Aries through Sagittarius — 7+16+9+21+5+9+16+7+10 = 100, and 100 is Savya pada 1’s paramayush. The table is self-consistent, and that consistency is how you can tell it has been transmitted correctly rather than approximately.

Some sequences repeat a sign within their nine. That is not an error either — see the FAQ. It is what makes those particular padas add up.

The balance at birth

Kalachakra is the only rashi dasha in the app with a balance. Chara, Narayana, Sthira, Shoola and Mandooka all start clean at birth. Kalachakra winds back, because — like Vimshottari — it is seeded from a Moon that was already part-way somewhere when you were born.

The measure is the degrees traversed within the pada, not within the nakshatra. If your Moon is 40% of the way through its pada, then 40% of your paramayush has notionally elapsed — and note that this is 40% of the whole 100-year span, not 40% of the first sign’s period. The engine winds the sequence back by that many years from your birth date and lets the periods fall where they fall.

The consequence surprises people: a Moon well into its pada can mean your first two or three sign periods began and ended before you were born, and the chart opens mid-sequence. That is correct, and it is what makes the later boundaries land where other software puts them.

What we do not compute

• We repeat the cycle past paramayush. Your sequence is nine signs summing to 83–100 years. To keep the timeline usable for a native who outlives that, the engine loops the nine signs round again. The tradition treats paramayush as a span, not a repeating cycle, so the periods we print past your paramayush are our coverage device rather than a classical claim. Read them with that in mind.
• No Deha and Jeeva. Kalachakra’s classical apparatus includes Deha (body) and Jeeva (life) rasis and a body of rules about what happens when the dasha touches them. We compute the sequence and the periods; we do not compute Deha, Jeeva, or any longevity verdict drawn from them. If you read Kalachakra for longevity, you are reading a part of the system we do not implement.
• No gati or Mandooka-leap jump rules. Several presentations of Kalachakra carry rules about the wheel jumping — skipping ahead or reversing — under specific conditions. Our sequence runs straight through its nine and repeats.
• The tables are PyJHora’s, verbatim. The group memberships, the nine-sign sequences, the paramayush figures and the rasi-years are transcribed from the PyJHora baseline this repo follows throughout, not re-derived from a Sanskrit source. Kalachakra is the system on which the published traditions most visibly disagree with one another — different texts print different sequences for the same pada. We ship one lineage consistently rather than blending several inconsistently. If your family’s almanac gives a different sequence for your pada, it is probably not wrong; it is probably a different lineage.
• No applicability condition is checked. We compute Kalachakra for any chart.

The antardashas — and one thing we get right

Kalachakra’s sub-periods are worth calling out, because they are the exception in their own family.

Every other rashi dasha divides a parent period into twelve sub-periods of one-twelfth each. Kalachakra divides into nine, and — under the default CLASSICAL setting — proportionally to the same rasi-years table above. The sequence is your pada’s own nine signs, rotated to begin at the parent sign; the weights are those signs’ years. So inside a Cancer Mahadasha, the Cancer antardasha takes 21/100 of it and the Capricorn antardasha takes 4/100 — not 1/9 each, and not 1/12 each.

That is a genuine, chart-derived correction over the uniform split, and it is switchable: EQUAL falls back to the stateless twelve-sign one-twelfth division that the other rashi dashas use. If your Kalachakra drill shows nine uneven children, CLASSICAL is on and you are seeing the real rule.

Notes on this timeline

• Periods are signs, not grahas. Read each through your own chart.
• Seeded from the Moon’s nakshatra pada — 3°20’ of arc; a pada boundary replaces the sequence, it does not merely shift the dates.
• Nine signs per cycle, summing to a paramayush of 83, 85, 86 or 100 years.
• The rasi-years are fixed for everyone; only the sequence varies by pada.
• Has a balance at birth, measured in degrees within the pada against the full paramayush — the only rashi dasha in the app that does.
• Because it hangs on the Moon’s longitude, the dates move with the ayanamsha.
• Antardashas are nine signs, proportional to the rasi-years — the exception to the family’s equal-twelfth rule.
