What is Mahadasha vs Antardasha?

Mahadasha is the major planetary period — each graha (Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, Ketu, Venus) rules a fixed span of years totalling 120. The Antardasha is a sub-period within each Mahadasha, giving a more granular picture. For example, during a 16-year Jupiter Mahadasha, you will pass through nine Antardashas (Jupiter–Jupiter, Jupiter–Saturn, etc.), each lasting months to years.

Why is birth time important for Dasha calculation?

The Vimshottari Dasha sequence starts from the Moon's exact nakshatra position at birth. Even a 15-minute difference can shift the nakshatra pada (quarter) and change the remaining balance of the first Mahadasha by several months. This cascading shift affects every subsequent period. If birth time is unknown, the calculator assumes 12:00 noon, which may reduce accuracy.

Can Dasha predict the future?

Dasha indicates which planetary themes are active — not fixed events. A Saturn Mahadasha highlights discipline, responsibility, and karmic lessons; it does not dictate specific outcomes. Jyotish offers guidance and timing context, not deterministic prediction. How you respond to each period's themes — through awareness, effort, and appropriate seva — shapes the actual experience.

How accurate is this calculator?

Daanyam computes Dasha using Swiss Ephemeris-grade planetary positions and classical rules from Brihat Parashara Hora Shastra (BPHS). The calculation is astronomically precise to the second. Interpretation accuracy depends on correct birth time — the tool highlights this requirement before submission.

How is Dasha different from Western astrology transits?

Western astrology times life events mainly through transits and progressions — where planets are in the sky now relative to your chart. Vimshottari Dasha is unique to Jyotish: a fixed 120-year sequence set at birth by the Moon's nakshatra, independent of current planetary motion. Astrologers read Dasha first for the life chapter, then layer transits (like Sade Sati) on top for fine timing.

Which ayanamsha does the Dasha calculator use?

Daanyam uses the Lahiri (Chitrapaksha) ayanamsha, the Government of India standard and the most widely used in modern Jyotish. Ayanamsha choice shifts the sidereal Moon position, so a different ayanamsha (like Raman or KP) can occasionally place a borderline Moon in the neighbouring nakshatra and change the Dasha sequence — which is why consistent, standard settings matter.

Is the Dasha calculator free?

Yes. The Mahadasha and Antardasha timeline, current-period reading, and end dates are completely free, with no sign-in required. A deeper Dasha Patrika PDF — with Pratyantardasha timing, remedies, and period-by-period guidance — is available as an optional paid report.

What is the 120-year Vimshottari cycle?

Vimshottari means '120' in Sanskrit. The system distributes 120 years across nine grahas in a fixed order: Ketu (7), Venus (20), Sun (6), Moon (10), Mars (7), Rahu (18), Jupiter (16), Saturn (19), Mercury (17). The cycle repeats endlessly, but since average human lifespan is shorter, most people experience only 5–7 Mahadashas. The starting point depends on the Moon's nakshatra at birth.
