The Vimshottari cycle compressed into a single varshaphal year: each lord holds the same SHARE of the year that it holds of the 120-year cycle, so the Sun receives eighteen days where it receives six years. Returns all eighty-one sub-periods - nine lords, nine sub-lords each - with the start of each as an ISO timestamp and its length in days. The whole cycle sums to roughly 360 days. WORTH KNOWING: this is read INSIDE the annual chart and is not a second opinion on the natal Vimshottari at /api/astro/dasha/vimshottari/. The two will not agree and are not meant to - one divides a life, the other divides a year.

Content-Type: application/jsonRequest 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 -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 |
| ayanamsa | string | optional | |
| 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 |
| year | integer | optional | Year of birth as a number, e.g. 1990. Four digits. min 1900 · max 2200 |
