Get Moon Phases & Void-of-Course Windows

What it does

Moon Phases & Void-of-Course gives you the upcoming lunar schedule in one call — no input required. It returns the next 12 upcoming Moon phases (new, first quarter, full, last quarter) and the next upcoming void-of-course windows, starting from right now.

The response includes two top-level sections: phases (with its own count) and voc_windows (with its own count). Each phase item gives you phase and exact_utc. Each void-of-course window gives you start_utc, end_utc, leaving_sign, and entering_sign — marking exactly when the Moon makes its last aspect before going void, and when it ingresses into the next sign to end the void period.

Use this endpoint when you need lunar-timing awareness for scheduling, publishing, or ritual-planning logic — for example, showing the upcoming phase calendar while also flagging void periods to avoid for launches, signings, or important decisions. Because both datasets are forward-looking from "now" with zero setup, it's a drop-in feed for dashboards, astrology apps, and calendar integrations that need the full near-term lunar picture without stitching together two separate calls.
