How it works
Given latitude, longitude and date, we compute the hour angle of the sun using orbital mechanics. Solar noon is when the sun crosses the local meridian; sunrise and sunset are when the sun is 0.833° below the horizon (accounting for atmospheric refraction).
Formula
Sunrise/sunset zenith angle: 90.833° (accounts for refraction + sun disk)
