How to Use the Tahajjud Calculator

A Tahajjud Calculator is a digital tool that helps Muslims determine the best time to wake up and pray Tahajjud — a voluntary night prayer performed during the last third of the night, between Maghrib and Fajr.

What Is Tahajjud?

Tahajjud is one of the most spiritually rewarding prayers in Islam, often prayed after sleeping for a portion of the night. The Qur’an and Hadith emphasize its immense reward, particularly in the final third of the night when Allah is closest to His servants.
