Vimshottari Dasha Antardasha Calculator
Enter a Mahadasha start date and Mahadasha lord to generate all nine Antardasha periods automatically.
Sequence and duration are based on standard 120-year Vimshottari proportions.
What is a Dasha and Antardasha?
In Vedic astrology, a Dasha is a planetary period, while an Antardasha (also called Bhukti) is a sub-period within that major period. The most widely used system is Vimshottari Dasha, which spans a full cycle of 120 years distributed among nine planets.
People often use a dasha antardasha calculator to quickly map timelines, understand planetary themes, and align life events with their astrological periods.
How this calculator works
1) Choose Mahadasha start date
This should be the exact date your Mahadasha began, based on your birth chart analysis or trusted astrology software.
2) Select Mahadasha lord
The calculator uses standard Vimshottari years for each planet:
- Ketu: 7 years
- Venus: 20 years
- Sun: 6 years
- Moon: 10 years
- Mars: 7 years
- Rahu: 18 years
- Jupiter: 16 years
- Saturn: 19 years
- Mercury: 17 years
3) Pick a check date
The tool identifies which Antardasha is active on that date. This is useful for current-period analysis or event timing review.
Understanding the output
- Antardasha: Sub-period lord inside your selected Mahadasha.
- Start / End Date: Timeline boundaries for each Antardasha.
- Duration: Approximate length in days and years.
- Running period highlight: The row active on your selected check date appears highlighted.

Best practices for accurate use
- Use correct birth data when deriving Mahadasha start date.
