One of the most common questions Muslims face when traveling or moving to a new city is: how do I find accurate prayer times? The answer depends on understanding how prayer times are actually calculated.

How Are Prayer Times Calculated?

Islamic prayer times are based on the position of the sun relative to your geographic location. The five daily prayers correspond to specific solar events:

  • Fajr — Dawn, when the sun is a specific number of degrees below the horizon
  • Dhuhr — Solar noon, when the sun reaches its highest point
  • Asr — Afternoon, when the shadow of an object equals its length (or twice its length)
  • Maghrib — Sunset
  • Isha — Night, when darkness sets in

Why Are There Different Calculation Methods?

Different Islamic scholarly bodies around the world have set slightly different angular values for Fajr and Isha. The most widely used are:

  • University of Islamic Sciences, Karachi — Used in Pakistan, Bangladesh, India, Afghanistan
  • ISNA (North America) — Used in the USA and Canada
  • Muslim World League (MWL) — Used in Europe, Far East, parts of America
  • Egyptian General Authority — Used in Africa, Syria, Lebanon, Malaysia
  • Umm Al-Qura (Makkah) — Used in Saudi Arabia

Which Method Should I Use?

Use the method adopted by Islamic scholars in your country or region. If you are unsure, the University of Islamic Sciences Karachi method is widely accepted across South Asia, while MWL works well for most of Europe.

Asr Time: Shafi and Hanafi Difference

There is a well-known difference between the Shafi/Maliki/Hanbali madhabs and the Hanafi madhab regarding Asr time:

  • Standard (Shafi) — Asr begins when the shadow of an object equals its own length
  • Hanafi — Asr begins when the shadow equals twice the object's length

This can result in a difference of 30 minutes to over an hour depending on your location and season. Follow your madhab accordingly.

Get Prayer Times Based on Your Exact Location

The most accurate way is to use GPS coordinates. The DuaSalaam Prayer Times page calculates Salah times based on your exact location with support for 14 different calculation methods.

Traveling? Here Is What to Do

When traveling, always recalculate prayer times for your current location — prayer times change significantly with latitude and longitude. Also remember that a traveler (musafir) covering more than 77–88 km may combine and shorten prayers according to the Sunnah.
