- Aqrbaul-Ayyam: i.e. the last day when 18 degree time is available is used until 18 degrees becomes available again
- Nisful-Layl: which means that if the time between sunset and (the next) sunrise is split into two parts, the last portion will be considered as Subh Sādiq i.e. the beginning of Fajr. This is the mirror of Dhuhr start so if your Dhuhr is at 13:12 then your Fajar is 01:12
- Standard Hanafi Madhab: Pray 30 minutes or so before sunrise
