Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
date | string | yes | Date for the Tamil panchanga, YYYY-MM-DD. |
lat | number | yes | Latitude in decimal degrees, north positive. |
lon | number | yes | Longitude in decimal degrees, east positive. |
timezone | string | no | IANA timezone of the location. |

What it covers
The three periods are eighths of the daytime from sunrise to sunset by the Tamil weekday table. The emagandam key is the Tamil spelling of Yamagandam and repeats the same period. For tithi, nakshatra and the full timings use asterwise_get_panchanga.
Workflow
BEFORE: asterwise_geocode — when you only have a place name.
AFTER: asterwise_get_panchanga — the day's limbs and other timings.
Input
date (YYYY-MM-DD), lat, lon, timezone (IANA, default Asia/Kolkata).
Output contract
data.date, data.sunrise, data.sunset (HH:MM local), data.tamil_month, data.rahu_kalam, data.yamagandam, data.kuligai, data.emagandam (same as yamagandam): start, end, duration_minutes, is_active. data.nalla_neram[]: start, end.
Errors
INVALID_PARAMS (local): bad date or coordinates. INTERNAL_ERROR: upstream failure.
Do not confuse with
asterwise_get_rahu_kaal — the same three periods without the Tamil month or Nalla Neram.
asterwise_get_panchanga — the full panchanga day.
