Free Vimshottari Dasha Calculator — Mahadasha & Antardasha Timeline
Vimshottari daśā is the classical Vedic system for sequencing roughly 120 years of life into periods (mahadasha) ruled by each of the nine grahas in turn, further divided into sub-periods (antardasha). This tool computes your complete, real timeline — current mahadasha, current antardasha, and the full sequence — from your exact birth details.
How the Vimshottari sequence is determined
The system starts from your Moon's exact position at birth — specifically, which nakshatra it occupies, since each of the twenty-seven nakshatras is assigned one of the nine grahas as its ruling lord. That lord's mahadasha is the one you are 'born into,' and how far your Moon has already moved through that nakshatra determines how much of the first period had already elapsed at birth. From there, the nine grahas run in a fixed classical order — Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury — each for its own fixed number of years (Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17 — totalling 120), cycling through the full sequence.
Mahadasha and antardasha — the two layers
A mahadasha is the major period — years to decades long, depending on the ruling graha. Within each mahadasha, all nine grahas also run as antardasha (sub-periods), in the same fixed sequence starting from the mahadasha's own lord, proportionally sized to the mahadasha's total length. This tool shows both layers: your current mahadasha and antardasha at the top, and the complete sequence of mahadashas with their date ranges below.
How tradition reads a dasha period
Classical texts read a mahadasha as a season where that graha's significations — and the houses it rules and occupies in your chart — are emphasized, coloured by that graha's own strength (dignity, aspects) in your specific chart. The same mahadasha lord expresses very differently in an exalted, well-aspected placement versus a weak, afflicted one — which is why a dasha timeline alone, without the graha's actual chart strength, is only half the classical picture.
Why Vimshottari, among several dasha systems
Classical Vedic astrology actually describes several daśā systems beyond Vimshottari — Ashtottari, Yogini, and Kalachakra among them — each with its own logic for sequencing planetary periods. Vimshottari is by far the most widely referenced in both classical texts and modern practice, which is why it is the default this tool computes; it is not that the other systems are wrong, simply that Vimshottari is the common shared reference point most readers and astrologers use first.
What this timeline does not do
This tool computes the classical date ranges — it does not predict specific events within any period, and it makes no claim about what 'will' happen during a given mahadasha or antardasha. Reading dasha periods against your chart's actual planetary strengths is exactly what a full reading (free to start) walks through, period by period.

Common questions
- What is Vimshottari dasha?
- Vimshottari daśā is the classical Vedic system dividing roughly 120 years into periods (mahadasha) ruled in turn by each of the nine grahas, starting from the ruling lord of your Moon's nakshatra at birth. It is the most widely used timing system in Vedic astrology.
- How is my dasha sequence determined?
- It starts from your Moon's exact nakshatra at birth — each of the twenty-seven nakshatras has one of the nine grahas as its ruling lord, and that lord's mahadasha is the one you're born into. How far your Moon had already moved through that nakshatra determines how much of the first period had elapsed before your birth date.
- What is an antardasha?
- An antardasha is a sub-period within a mahadasha — all nine grahas run as antardasha inside each mahadasha, in the same fixed classical sequence, proportionally sized to the mahadasha's length. Your current antardasha is often read as a finer-grained modifier on your current mahadasha's broader theme.
- Does my dasha timeline predict specific events?
- No. A dasha period is traditionally read as emphasizing a graha's themes and the houses it touches in your chart — not as a scheduled event. The same period plays out very differently depending on that graha's actual strength and placement in your individual chart, which a dasha date range alone does not show.
- How accurate is my dasha timeline without an exact birth time?
- The dasha sequence and roughly which mahadasha you are in are usually stable across a birth-time estimate of a few hours, since they hinge on your Moon's nakshatra, which moves slowly. The precise start and end dates of each period can shift by days depending on birth-time accuracy — if you only know an approximate time, treat the exact dates as indicative rather than exact.
