Request fields

FieldTypeRequiredNotes
latitudenumber (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

longitudenumber (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_directionstringoptional
forwardbackward
dasha_startstringoptional

Which cycle the timeline opens on.

currentnextprevious
date_timestring (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.

datetimestring (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_yearnumber (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

levelsintegeroptional

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

nodestringoptional

Lunar node model. Required by the rashi parent, which does not default it; defaulted here.

truemean
timezone_as_floatnumber (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.
