These dates were calculated from the birth details you entered. The period names and boundaries are calculation outputs; what a period may mean in a specific life requires a separate, chart-specific interpretation. If your birth time is a best guess, the boundaries may move. Get the free Vedic report to see a focused timing map alongside your chart pattern.
What is the Vimshottari dasha system?
Vimshottari Dasha is a nakshatra-based planetary-period system in Parashari Jyotish. Its nine lords follow a fixed repeating order, with assigned durations that total 120 years. In the standard Moon-based method, the Moon's birth nakshatra identifies the starting lord and the untraversed portion of that nakshatra determines how much of the first mahadasha remains. Each mahadasha is then divided into nested antardashas.
| Planet | Mahadasha length |
|---|---|
| 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 |
The lord order and assigned lengths are fixed within this method. Your starting point and first-period balance depend on the Moon's position within its birth nakshatra.
What the calculator shows and what it does not
The calculator shows period names and boundaries produced from the birth details you enter. It uses the Lahiri sidereal zodiac and the standard Moon-nakshatra Vimshottari sequence. Those results do not, by themselves, predict an event or explain how a period will feel. A chart-specific reading considers the active planet's functional role, placement, condition, supported relationships, and place in the wider period hierarchy.

Dasha FAQ
What dasha am I in right now?
In the standard Moon-based method, your Moon's nakshatra at birth identifies the starting lord and the untraversed portion determines how much of the first period remains. Enter your birth date, clock time, and place to calculate your current mahadasha and antardasha with their displayed start and end dates.
What is a mahadasha and an antardasha?
A mahadasha is a major planetary period lasting 6 to 20 years depending on the lord. Each mahadasha contains nine antardashas in the same repeating order, scaled proportionally inside the larger period. The pair identifies two nested levels of the calculated timeline.
How long does each dasha last?
The assigned mahadasha lengths total 120 years: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, and Mercury 17. The order is fixed; the starting point and first-period balance depend on the Moon's position in its birth nakshatra.
Do dasha dates depend on my exact birth time?
Use the closest clock time you know. The calculator uses that specific time; an uncertain birth time can shift Dasha boundary dates.
