How Aleppo's times are computed
For Aleppo (36.23° N, 37.17° E) Hourora computes the sun's position for each date and solves for each prayer: Fajr 18°, Isha 17°. Asr uses the standard shadow rule. The times are shown in UTC+3, daylight saving included.
The default is the method usually published in Syria: Muslim World League. You can choose another method, the Asr rule and the high-latitude rule above; the choice is saved on this device.
