Dwisaptati Sama dasha

The 72-year conditional cycle, with equal periods. Another equal-period system. Its brevity relative to Vimshottari means a chart moves through lords quickly, which is part of why it is read where it applies. This is a CONDITIONAL dasha: the classical texts apply it only when a particular configuration holds in the chart, so it is not a reading that is admissible for everyone. Call /api/astro/dasha_applicability/ to test which conditional dashas a given chart actually admits before you show one.

Request fields

Field	Type	Required	Notes
latitude	number (double)	required	Latitude of the place, in decimal degrees. Positive is north, negative is south. Example: 26.9124 for Jaipur, 40.7128 for New York. Minutes and seconds are not accepted - convert first. min -90 · max 90
longitude	number (double)	required	Longitude of the place, in decimal degrees. Positive is east, negative is west. Example: 75.7873 for Jaipur, -74.0060 for New York. Note the sign: a missing minus puts New York in China. min -180 · max 180
dasha_direction	string	optional	`forwardbackward`
dasha_start	string	optional	Which cycle the timeline opens on. `currentnextprevious`
date_time	string (date-time)	optional	The moment to calculate for, ISO 8601. ALWAYS include an offset or a trailing Z - a value with no zone is read as Asia/Kolkata (UTC+05:30), not UTC, and can return the previous day's result with a 200. '2026-09-01T06:00:00Z' and '2026-09-01 06:00:00' are different instants and give different answers.
datetime	string (date-time)	optional	The moment to calculate for, ISO 8601. ALWAYS include an offset or a trailing Z - a value with no zone is read as Asia/Kolkata (UTC+05:30), not UTC. Same meaning as date_time, which other endpoints call the same thing by a different name.
days_in_year	number (double)	optional	Year length the periods are measured in. 360 for the classical savana year, 365.25 for the Julian year. min 360 · max 365.256364
levels	integer	optional	How deep to nest: 1 mahadasha only, 2 adds antardasha, 3 adds pratyantardasha. Capped at 4 because the response grows roughly tenfold per level. min 1 · max 4
node	string	optional	Lunar node model. Required by the rashi parent, which does not default it; defaulted here. `truemean`
timezone_as_float	number (double)	optional	UTC offset of the place, in hours, as a decimal. Example: 5.5 for India (UTC+05:30), -5 for New York in winter, 5.75 for Nepal. This is NOT validated against date_time - if the two disagree you get a successful response for the wrong moment, so derive both from the same source. Use the offset in force on that date, not today's: a summer birth in a country with daylight saving needs the summer offset. min -12 · max 14
