​
Understanding Calculation Angles

The calculation angles represent the sun’s position below the horizon:
  • Fajr: When the sky begins to lighten before sunrise
  • Isha: When the sky becomes completely dark after sunset
  • Maghrib: Typically calculated as minutes after sunset or angle below horizon
Different scholarly opinions and geographic locations lead to different angle preferences. Choose the method recommended for your region or consult with local Islamic authorities.
Changing calculation methods will affect all prayer times. Ensure you select the method appropriate for your location and scholarly tradition.
