Vimshottari dasha calculator
The 120-year Vimshottari sequence begins at the Moon's exact position inside its birth nakshatra. The arithmetic is deterministic.

What this calculator returns
The result lists the mahadashas that begin during the first 120 years from birth, highlights the period active today, and expands its nine antardashas with calendar boundaries.
Inputs and accuracy
A missing birth time uses local noon. That can shift the Moon and therefore the period boundaries, especially near a nakshatra edge; treat those dates as approximate until the time is known.
Calculation method
Planetary longitudes come from Swiss Ephemeris. Tropical positions use the seasonal zodiac; Vedic positions use Lahiri ayanamsa. Read the exact calculation method and limitations.
