Vimshottari dasha is the most widely used planetary period system in Vedic astrology, dividing a person's life into a fixed 120 year cycle split across the nine grahas (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu), each ruling a maha-dasha (major period) of a fixed length: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19 and Mercury 17, always cycling in that fixed order regardless of which planet starts your personal sequence.

Your own sequence starts from whichever planet rules your birth nakshatra, at whatever point inside that planet's period corresponds to how far the Moon had already travelled through that nakshatra at your birth. This is why your dasha timeline is calculated directly from your Moon's exact nakshatra and its unelapsed fraction at birth: this calculator reports your balance at birth (the lord and remaining years of the maha-dasha you were born into) as the anchor point everything else is built from.

Each maha-dasha further divides into nine antardashas (sub-periods), one for each of the nine planets in the same fixed order, proportionally sized to the antardasha lord's own dasha length within the maha-dasha's total span. This calculator reports your current maha-dasha and current antardasha together, since classical timing prediction is generally read from the combination of the two, not the maha-dasha alone: a naturally difficult maha-dasha lord running through a supportive antardasha lord's sub-period often plays out quite differently than the same maha-dasha's more challenging antardashas.

We also report your current pratyantar-dasha, a finer sub-division within the current antardasha, again following the same fixed nine-planet cycle proportionally scaled down one level further. Some traditions consider timing predictions down to the pratyantar level for especially specific questions (a particular month rather than a particular year), though the maha and antar levels together are what most general readings rely on.

This calculator also lists your next two upcoming antardashas with their start and end dates, so you can see not just where you are now but what is coming next in your timeline without having to compute the whole 120 year cycle by hand. A dasha or antardasha change is one of the most classically significant timing markers in a reading, since a shift from one planetary period to another is read as a genuine change in life theme, even when nothing external has visibly changed yet.

Because your entire dasha timeline is anchored to your Moon's nakshatra and its precise unelapsed fraction at birth, an inaccurate birth time is one of the most common reasons a computed dasha timeline turns out to be wrong: even a birth time error too small to shift your nakshatra itself can measurably shift the exact balance of years remaining in your first maha-dasha, and that error compounds forward through every later period since each one is calculated relative to the last. This is why, like lagna, this calculator will not guess a dasha result from an unknown or noon-placeholder birth time.

A dasha lord's effect is also read differently depending on where that planet actually sits in your own chart: its own house, its dignity, and which houses it rules for you specifically. The same Saturn maha-dasha plays out differently for a chart where Saturn sits strong in a supportive house than for one where it sits weak or afflicted, which is exactly why a dasha calculator that only names the current period, without the rest of the chart behind it, can tell you what time it is but not fully what that time means for you.
