Ashtottari Dasha — 108-Year Planetary Cycle

108-Year Cycle

Ashtottari totals 108 years across 8 planet periods: Sun (6), Moon (15), Mars (8), Mercury (17), Saturn (10), Jupiter (19), Rahu (12), Venus (21). Ketu is excluded — a key structural difference from Vimshottari.

Rahu Eligibility Rule

Ashtottari applies when Rahu is in the 1st, 3rd, 6th, 7th, 10th, or 11th house from the Lagna or Moon (depending on classical source). AstroShri computes eligibility from your chart automatically.

Longer Sub-Periods

Ashtottari antardasha periods are proportionally longer than Vimshottari's because the mahadasha allocation differs. Jupiter's 19-year period is the longest in Ashtottari, versus Rahu's 18 in Vimshottari.

Alternative Lens

Charts where Rahu plays a dominant role — particularly those born with strong Rahu configurations — often show better event correlation under Ashtottari than Vimshottari.

Is Ashtottari Dasha applicable to my chart?

Ashtottari applies specifically to charts where Rahu occupies certain houses at birth. The classical condition per Parasara Hora Shastra is that Rahu must be in 1, 3, 6, 7, 10, or 11 from Lagna (with additional conditions per sub-commentary). AstroShri checks this automatically and shows your Ashtottari timeline if the rule is met.

Why is Ketu excluded from Ashtottari?

Ashtottari is an 8-planet system (ashta = eight, uttari = superior), derived from a tradition that treats Rahu and Ketu as a paired node rather than two separate grahas. Rahu's influence covers both nodes' themes in this system. The 8 ruling planets are Sun, Moon, Mars, Mercury, Saturn, Jupiter, Rahu, and Venus.

How does Ashtottari relate to Vimshottari?

They are parallel timing systems computed from different bases. Vimshottari begins from Moon's nakshatra at birth using a 120-year 9-planet cycle. Ashtottari also begins from Moon's nakshatra but uses a 108-year 8-planet cycle with different period weights. When both are active, cross-checking them adds prediction confidence.
