How Kerman's times are computed
For Kerman (30.30° N, 57.08° E) Hourora computes the sun's position for each date and solves for each prayer: Fajr 17.7°, Isha 14°, Maghrib 4.5°. Asr uses the standard shadow rule. The times are shown in Iran Standard Time, daylight saving included.
The default is the method usually published in Iran: Institute of Geophysics, University of Tehran. You can choose another method, the Asr rule and the high-latitude rule above; the choice is saved on this device.
