Vimshottari Dasha Explained — The 120-Year Planetary Timeline
Vimshottari is the most widely used Dasha system in North Indian Jyotish. It divides life into planetary periods ruled by Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, and Mercury — each activating different houses and themes in your Janma Kundali.

How Vimshottari Dasha is calculated
Dasha calculation begins with your birth Moon Nakshatra. Each of the 27 Nakshatras is ruled by a planet in a fixed sequence. The proportion of the Nakshatra already completed at birth determines how much of the starting Mahadasha remains.
For example, if you were born late in Rohini (ruled by Moon), you may have only a few years of Moon Mahadasha left before Mars period begins. Software like AstroReeti uses precise lunar longitude — not approximate tables — so your Dasha start dates match professional Jyotish software.
Mahadasha, Antardasha, and sub-periods
Mahadasha is the major lord period lasting years (Saturn 19, Mercury 17, Jupiter 16, etc.). Within each Mahadasha, every planet rules an Antardasha sub-period proportional to its Mahadasha length. Finer Pratyantardasha and Sookshma divisions exist for event-level timing.
Interpretation combines the Dasha lord’s house ownership, placement, aspects, and strength (Shadbala, dignity). A strong Jupiter Mahadasha activating the ninth and tenth houses may bring education and career growth; an afflicted Saturn Antardasha may emphasise discipline, delay, or health themes depending on chart context.
Using Dasha in prediction
Dasha tells you which planet’s significations are “online.” Transits trigger events — especially when transit Saturn or Jupiter aspects Dasha lords or their houses. Marriage often appears during Venus or Jupiter sub-periods when seventh house conditions support union. Career shifts may cluster in Sun, Mercury, or tenth-house activations.
Dasha never overrides free will or practical choices. It is a timing lens Jyotishis have used for centuries to prepare clients for productive or cautious phases. AstroReeti visualises your full timeline and lets Reeti explain each period in conversational language tied to your actual chart.
