-d '{"date_time":"2026-09-01T06:00:00+05:30","timezone_as_float":5.5,"latitude":26.9124,"longitude":75.7873}'The shadow points, in the two families they come from. `from_sun` holds the five derived arithmetically from the Sun's sidereal longitude - Dhuma, Vyatipata, Parivesha, Indrachaapa and Upaketu - each a fixed offset from the one before, so they depend only on the moment. `from_day_division` holds the six derived by splitting the daylight or the night into eight planetary parts, including Gulika and Mandi. These depend on the PLACE as well as the moment, which is why the two families are returned separately rather than merged into one list.
| 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 | |
