- SunCalc 2.0.1 (BSD-2-Clause) computes every event as a UTC instant from Meeus/NOAA-derived geometry; the page then renders those instants on the clock of the place you picked.
- A geometric ephemeris, not an almanac: about a minute of accuracy for 1900-2100, which is why dates outside that range are refused instead of silently degrading.
- Sunrise and sunset are horizon events. They assume a flat horizon at your coordinates. Hills and buildings shift the moment you actually see.
- Polar day and polar night are named as such, with the phase table honestly showing nulls.
