Amrit kaal

Amrit kaal: the day's most favourable windows. Returned as a LIST under `windows`, not a single window, because a day can hold two. An empty list is a valid answer - some days have none.

Test Request

Authentication

X-API-Key: yt_live_a1b2c3d4_…
Content-Type: application/json

Request fields

Field	Type	Required	Notes
date_time	string (date-time)	required	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.
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 -89.9 · max 89.9
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
timezone_as_float	number (double)	required	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
dhuma_vyatipata_relation	string	optional	`360_minus_dhumadhuma_plus_53_20`
eccentric_anomaly	number (double)	optional
eccentricity	number (double)	optional
gulika_portion	string	optional	`saturneighth`
gulika_rises_at	string	optional	`beginningmiddleend`
kala_mrityu_rise_at	string	optional	`beginningmiddleend`
keys	array	optional	Which calculations to return, as a list of names. See the key table for this endpoint; an unrecognised name rejects the whole request. One call costs one credit however many keys you ask for, so request everything you need at once rather than making several calls.
mandi_portion	string	optional	`saturneighth`
mandi_rises_at	string	optional	`beginningmiddleend`
mean_anomaly	number (double)	optional
mode	string	optional
nakshatras	string	optional
samvata_type	string	optional
tolerance	number (double)	optional
