Dasha × transit.

By the Dasha90 team · published 31 Aug 2026

IN FIVE-YEAR-OLD WORDS

You have two clocks: your own life-clock (dasha) and the sky’s clock everyone shares (transits). When both clocks say the same kind of thing at the same time, we draw a box around those dates — that box is a window.

Two different clocks

You have two clocks: your own life-clock (dasha) and the sky-clock everyone shares (transits). The same sky-day feels different in different personal seasons, so we always read both together.

Jyotisha times life with two instruments. The dasha is a personal clock, wound once at birth by your Moon’s position and running on pure arithmetic ever since — see how Vimshottari dasha works. Gochar (transit) is the public clock: where the planets actually are right now, read against your birth chart.

Tradition insists on reading them together. A dasha names the theme of the chapter; the transits mark the weather inside it. The same Jupiter transit lands differently in a Saturn mahadasha than in a Venus one.

the personal clock — one period always carries sub-periods inside it

How a 90-day window emerges

In any 90 days the sky does a few countable things — planets change rooms or pause. When a helpful sky-thing happens inside a helpful personal season, we draw a box around those dates. That box is a window, and its dates are copied exactly, never invented.

two clocks over the same 90 days — the overlap is the window

Over any 90 days, a few concrete, computable things happen: planets change signs (ingresses), stations turn motion retrograde or direct, and the slow movers — Saturn, Jupiter, Rahu — hold houses from your Moon and ascendant. Lay your running mahadasha–antardasha stack over that calendar and the overlaps become dated windows.

RULE · SUPPORTIVE

Jupiter transits the 5th, 9th or 11th sign from your Moon

SUPPORTIVE WINDOW

RULE · EFFORT

Saturn stations (turns retrograde or direct) within ±3 days

HIGHER-EFFORT WINDOW

RULE · CAUTION

Mercury runs retrograde through your 90 days

COMMUNICATION CARE

In a Dasha90 reading those windows come from a fixed, deterministic rule table applied to computed events — the writing layer must copy the dates verbatim and cite the facts behind each window, and it cannot invent or move them. That is the difference between “a good week is coming” and a dated span you can check against the published conventions.

Try it on your own chart

Try the free calculator to see your own clock. The full reading adds the sky-clock, the windows, and the story — in English, हिंदी or Hinglish.

Start with your side of the equation — the running mahadasha, antardasha and pratyantardasha, computed to the second in the free calculator. The full 90-day reading adds the transit calendar, the windows, and a written interpretation in English, हिंदी or Hinglish. The sample report shows the whole thing uncut.

What this does not claim

Windows are days to watch, not promises. Neither clock guarantees anything — and that’s exactly what we’ll always tell you.

Windows are periods to observe, not forecasts of events. Neither dasha nor transit — separately or combined — guarantees outcomes, and none of this is medical, legal, or financial advice. Astrology is a traditional symbolic system; we compute its inputs honestly and interpret them as a lens for reflection.
