Vimshottari Dasha — Your Planetary Timeline
The classical Vedic period system: which graha holds the timeline right now, at every nested level, and when the next shift arrives. Anchored to the Moon’s sidereal nakṣatra at birth, computed by the engine on JPL DE440.
The 120-Year Vedic Planetary Lifecycle
In traditional Indian astrology (Jyotish), the Vimshottari Dasha system maps a life onto a 120-year cycle of nine planetary rulers, each holding the timeline for a fixed span. It is a traditional period model — a way of naming chapters — not a deterministic account of a person’s life.
The Lunar Starting Anchor
The starting lord and its balance come from the Moon’s sidereal longitude within one of 27 nakṣatras (13°20′ each). The lord of the birth nakṣatra rules first; the fraction of the nakṣatra still ahead of the Moon sets how much of that lord’s period remains at birth.
The Nine Major Periods
The cycle follows an invariable order, summing to 120 years:
Nested Fractal Time
Each Mahādaśā subdivides into nine Antardaśās, starting with its own lord and proportional to each lord’s share of 120 years; each Antardaśā subdivides the same way into Pratyantardaśās. A long period can therefore hold short interludes of a very different tone.
Ayanamsha Systems & Boundary Sensitivity
A nakṣatra spans 800 arcminutes, so 1′ of lunar longitude moves the birth balance by 1/800 of the starting lord’s full period — about 3 days for the Sun’s 6 years and about 9 days for Venus’s 20. Every later boundary inherits that offset, so time input and ayanamsha policy matter more than they first appear to.
Lahiri is a widely used ayanamsha associated with Chitra Paksha conventions. Moira applies its documented formula and reduction inputs; an ayanamsha remains a selected sidereal reference policy, not a uniquely proven zodiac.
Only the birth balance depends on the Moon’s position. Every later boundary is fixed arithmetic on the declared year basis, shown with your results. The resulting precision remains bounded by the kernel, time input, ayanamsha, and that policy.
Near a Nakshatra boundary, a small change in time or policy can change the starting ruler. Compare the displayed Moon longitude with the boundary and test plausible input uncertainty; do not treat rectification as mechanically proven.
Test and compare your timeline against Krishnamurti (KP), Raman, Fagan-Bradley, and Yukteshwar ayanamshas to evaluate how slight fiducial differences alter sub-period boundaries.
Frequently Asked Questions
- Which Ayanamsha should I select?
- Moira defaults to Lahiri and also exposes other admitted ayanamsha policies. Choose the convention required by your practice or comparison source; the options are not claimed to be interpretively equivalent.
- Does a Saturn or Rahu Mahadasha always indicate hardship?
- No. In Jyotish, the outcome of any period depends strictly on the dignity, house ownership, and yogas formed by that planet in your chart. For Taurus or Libra ascendants, Saturn is a beneficial Yogakaraka planet capable of delivering remarkable professional authority and enduring accomplishments.
