About this dataset
Civil twilight, sunrise, sunset, moonrise, moonset by location. Sun/moon rise-set and civil/nautical/astronomical twilight times from the USNO RSTT one-day API (aa.usno.navy.mil) by coordinates; several in-app surfaces (dashboard widget, flight briefings, night-currency) also compute the same events locally from a solar-position algorithm as an offline fallback. Night-currency planning + AI sun-times tool.
Where this feed reaches
- Global — no regional boundary applies
A region on this list means we fetch it. It is not a promise of station density: a listed region can still have sparse or no reporting sites near a given airport.
