How this calculator works

This calculator uses the SunCalc library, which implements the astronomical algorithms from Jean Meeus' book "Astronomical Algorithms" (1991). Calculations incorporate atmospheric refraction (0.833 degree correction) at the horizon.

Accuracy

The calculator is accurate to within 1 minute for most locations below 70 degrees latitude. For polar regions (above 70 degrees), accuracy may decrease.
