How Ipoh's times are computed
For Ipoh (4.60° N, 101.06° E) Hourora computes the sun's position for each date and solves for each prayer: Fajr 18°, Isha 18°, with the authority's precautionary minutes. Asr uses the standard shadow rule. The times are shown in Singapore Standard Time, daylight saving included.
The default is the method usually published in Malaysia: JAKIM, Malaysia. You can choose another method, the Asr rule and the high-latitude rule above; the choice is saved on this device.
