FreeWhat is Shashtihayani Dasha?
Shashtihayani Dasha uses a 60-year cycle — "Shashtihayani" means "sixty years" in Sanskrit. This cycle length is astronomically significant because it approximates the Jupiter-Saturn conjunction cycle (approximately 59.6 years), which has been considered the most important planetary cycle in both Vedic and Western astrology for millennia.
The system distributes 60 years across the planets with the following allocations: Jupiter (10), Sun (10), Mars (10), Mercury (10), Venus (10), Saturn (10). Each of the 6 planets receives equal 10-year periods.
Shashtihayani is applied as a conditional dasha when specific birth conditions are met. Its 60-year cycle also corresponds to the traditional Hindu calendar system (Samvatsara cycle), which runs in 60-year cycles with each year having a unique name.
