How it Works

The Islamic "night" is defined as the duration between Sunset (Maghrib) and Dawn (Fajr). Unlike the Gregorian day which begins at midnight, the Islamic night is divided into three equal segments to determine the preferred times for voluntary prayers.

Step 1

Find the total duration (in minutes) from Maghrib to the following Fajr.

Step 2

Divide this total duration by three to find the length of each "third".

Step 3

Add two of these "thirds" to your Maghrib time to find when the last third begins.
