Planetary Hours
astroway_calendar_planetary_hoursRead-onlyIdempotent
Calculates Chaldean planetary hours for a date and location, returning 12 daytime and 12 nighttime hours; pass a local time to mark the current hour.
Instructions
Chaldean planetary hours for a date and place: 12 from sunrise to sunset and 12 from sunset to sunrise, so an hour is rarely 60 minutes. startHour and endHour are decimal local hours. Send atLocalHour (decimal local time, e.g. 15.2 for 15:12) to have the hour containing it marked isCurrent; without it no hour carries the field, because the answer is cacheable and a flag from the server clock would be stale by the time it renders.

Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| date | Yes | ||
| latitude | Yes | ||
| timezone | No | IANA zone name such as Europe/Kyiv, or auto to look the zone up from latitude and longitude. The server takes the offset that zone kept at this local date and time, summer time included, and uses it in place of timezoneOffset. A clock time that happened twice takes the first occurrence; one skipped when clocks went forward takes the offset from before the change. Abbreviations such as EST are refused. Before 1970 the tz database is not reliable for every place, so send timezoneOffset when the local clock is known. | |
| longitude | Yes | ||
| atLocalHour | No | Local time of day in decimal hours, e.g. 15.2 for 15:12. When sent, the hour containing it carries isCurrent: true and every other hour carries false. When omitted, no hour carries the field at all: it is not false, it is unasked. | |
| timezoneOffset | No | Hours from UTC at the given moment, not minutes. Fractional zones are hours too: 5.5 for India, 5.75 for Nepal, -3.5 for Newfoundland. Defaults to 0, meaning UTC. Ignored when timezone is sent. |
