What is a Pratyantar Dasha Calculator?
A Pratyantar Dasha Calculator is a tool that gives the sub-sub periods inside a Vimshottari Antardasha (Bhukti). Each Pratyantar refines the timing of results within its Antardasha, which itself runs inside a Mahadasha, so this third level shows much finer timing than the Mahadasha or Antardasha alone.
The formula is: each Pratyantar duration = (MD years x AD years x PD years) / 14,400 years, at 365.25 days per year. The nine Pratyantars run in Vimshottari order starting from the Antardasha lord: Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, in a 120-year cycle. This calculator uses the 365.25-day year method and states it openly.

Frequently Asked Questions (FAQs)
What is Pratyantar Dasha?
It is the third level of the Vimshottari dasha system - the sub-sub period running inside an Antardasha (Bhukti), which itself runs inside a Mahadasha. Each level refines the timing of results.
In what order do Pratyantars run?
They start from the Antardasha lord itself and then follow the fixed Vimshottari order - Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury - totalling 120 years over a full cycle.
How long is one Pratyantar?
From a few days to about a year, depending on the lords: duration = MD years x AD years x PD years / 14,400 years. Long-period lords like Venus and Saturn give longer Pratyantars.
Do different astrologers get the same dates?
Small differences are possible because some use a 365.25-day year and some a Savana (360-day) year for dasha conversion. This calculator uses 365.25 days and states the method openly.
