How do I find my current Mahadasha?

Enter your birth date, time and place. The calculator finds the Moon's nakshatra at birth, works out the remaining balance of the first period and lists the nine Mahadashas with their dates, plus the Antardashas of the current Mahadasha, marking the periods running today.

What is the difference between Mahadasha and Antardasha?

The Mahadasha is the major period of one planet, lasting 6 to 20 years. The Antardasha (also called Bhukti) is a sub-period inside it, ruled by each of the nine planets in turn. Readings combine both lords.

How accurate are the Dasha dates?

The dates depend on the Moon's exact position at birth. A birth time that is off by an hour moves the Moon about half a degree and can shift period dates by several months, so use the most accurate time you have.

Why do other Dasha calculators give different dates?

Software may use a different ayanamsa (this tool uses Lahiri) or a different year length (this tool uses 365.25 days; some use 360-day years). Both change the dates slightly.

How the Vimshottari Dasha works

The Vimshottari Dasha is the main timing system of Vedic astrology. It divides a 120-year cycle into nine planetary periods (Mahadashas): Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19 and Mercury 17. Each Mahadasha is divided into nine Antardashas (sub-periods) in the same order, each in proportion to its planet's years.

Your sequence starts with the ruler of the nakshatra the Moon occupied at birth. How far the Moon had already travelled through that nakshatra decides how much of the first period was left when you were born. This calculator shows your birth nakshatra, the Mahadasha and Antardasha you are in today and the dates of the periods ahead.

How it is calculated

The Moon is computed with Astronomy Engine (MIT) and converted to sidereal longitude with the Lahiri ayanamsa. The balance of the first period comes from how far the Moon has moved through its nakshatra; periods follow the 120-year Vimshottari sequence (1 year = 365.25 days).
