Get Planetary Hours API

What it does

Planetary Hours gives you the 24 unequal Chaldean hours for a specific latitude, longitude, and date. Send a date plus lat and lng, and you get the local day ruler, sunrise and sunset in UTC, and a full hour-by-hour schedule.

Each hour item includes its index, period (day or night), ruling planet in Chaldean order, and start_utc / end_utc timestamps. The response also echoes back the input date, lat, and lng, so you can store or audit the calculation without keeping the original request separately.

Use Planetary Hours when you need location-aware timing for astrology tools, ritual planners, or any application that depends on sunrise/sunset-based day partitions. Because the hours are unequal, the schedule is derived from the actual daylight and nighttime length at the requested coordinates rather than a fixed 60-minute clock.

It is a good fit for apps that need a deterministic planetary timetable for a given place and date, with enough detail to render a calendar, timeline, or hourly planner from the API response.
