Fajr and Isha Calculation Methods
Why Fajr and Isha can differ between calculation methods and countries.
Fajr and Isha depend on twilight, so calculation methods use different angles to define when each time enters. A different angle or local adjustment can shift the timetable by several minutes.
Some countries use Muslim World League, Umm al-Qura, Egyptian settings, or local official settings. Showing the method on each city page helps explain the difference.
Why These Two Times Differ More
Fajr before sunrise and Isha after Maghrib are tied to twilight brightness, so method differences are more visible than for Maghrib or Dhuhr.
When comparing two timetables, check city, timezone, and method before treating the difference as an error.
