What is the Astronomy and Time API?

Accurate astronomical calculations — moon phases, sunrise/sunset, twilight, seasons, zodiac signs, and eclipse calendars for any date and location. No external API dependencies.

Astronomy and Time API is available on the JoJ API marketplace. Subscribe with a single JoJ API key, call it through one gateway, and pay from one wallet — no separate account or contract with the provider.

Frequently asked questions about Astronomy and Time API

What can this API calculate?

Moon phase and illumination for any date, sunrise/sunset and civil, nautical and astronomical twilight for any GPS coordinates, equinoxes and solstices, the zodiac sign for a date, and eclipse calendars.

How do I get sunrise and sunset for my location?

Call GET /sun/today?lat=X&lon=Y for today, or GET /sun?lat=X&lon=Y&date=YYYY-MM-DD for any date. It returns sunrise, sunset, solar noon, day length and all three twilight phases.

Do you rely on any third-party services?

No. All results are computed locally from astronomical algorithms (JPL ephemeris–based), so responses are deterministic, dependency-free and returned in milliseconds.
