Mawqut is an astronomical prayer timer, it has two operating modes online/offline mode, in online mode it bases on sunrise-sunset.org to get the sunrise, the noon and the sunset which are the base of calculating all prayer times, and in offline mode those times are calculated internally, here is how it does the calculations:
- Al-Fajr is calculated internally based on Hour Angle Equation where by default it takes the astronomical twilight angle 18 degrees, the user can adjust the degree from the Settings screen.
- Al-Dhuhr is at the day noon.
- Al-Asr is calculated internally based on Hour Angle Equation where the solar zenith angle for Shafi’i is when the length of the object’s shadow equals the length of the object’s shadow at the noon plus the object’s height, and for Hanafi is when the length of the object’s shadow equals the length of the object’s shadow at the noon plus twice the object’s height.
- Al-Maghreb is at the sunset.
- Al-Ishaa is calculated internally based on Hour Angle Equation where by default it takes the astronomical twilight angle 18 degrees, the user can adjust the degree from the settings screen.
