What Are Athan Calculation Methods and Which One Should I Use?

Athan calculation methods determine Islamic prayer times based on the sun’s position. The main difference between methods lies in how they calculate Fajr and Isha, which vary due to twilight conditions in different regions.

Have you ever wondered why prayer times differ slightly depending on which app or website you use? The answer lies in the various Athan calculation methods. Here’s everything you need to know about how these methods work and how to choose the right one for you.

How Athan Calculation Works

Islamic prayer times are based on the sun’s position throughout the day:

  • Fajr: Begins when dawn breaks (15°–18° below horizon)
  • Sunrise: When the sun appears on the horizon
  • Dhuhr: Midday, when the sun passes its peak
  • Asr: When an object’s shadow equals its height (Standard) or doubles it (Hanafi)
  • Maghrib: Sunset, when the sun disappears below the horizon
  • Isha: When twilight fades (15°–18° below horizon or a set time after Maghrib)

Popular Athan Calculation Methods

Here are the most widely recognized methods globally:

  • Muslim World League (MWL): Fajr at 18°, Isha at 17°, common worldwide
  • ISNA: Fajr and Isha at 15°, best for North America
  • Umm al-Qura (Makkah): Fajr 18.5°, Isha fixed 90 mins after Maghrib
  • Egyptian General Authority: Fajr 19.5°, Isha 17.5°, used in Africa & Middle East
  • University of Karachi: Fajr & Isha 18°, common in South Asia

Why Do Methods Differ?

The variation mainly affects Fajr and Isha because twilight conditions differ by geography. Each method was developed based on regional observations and calibration, leading to slight differences in timing.

How to Choose the Right Method

  • Follow Local Authority: Use the method recommended by your mosque or Islamic center
  • Regional Fit: ISNA for North America, Umm al-Qura for Saudi Arabia, etc.
  • Madhab Consideration: Choose Standard or Hanafi Asr calculation based on jurisprudence
  • High Latitudes: Use dynamic adjustments for regions with extreme daylight variations
