The Hijri date may differ by one day depending on the moon sighting and the official announcement in your country.

Frequently asked questions

• When does Rabi' al-Thani 1451 AH start?

  Rabi' al-Thani 1451 AH starts on August 12, 2029 (Sunday) and lasts 29 days, according to the official Umm al-Qura calendar.

• Why does a Hijri month have only 29 or 30 days?

  A Hijri month is lunar: it begins with the birth of the crescent and ends at the next one. A lunar cycle takes about 29.5 days, so months alternate between 29 and 30 days.

• Why might the first day of the month in my country differ by one day?

  This calendar follows Umm al-Qura, adopted in Saudi Arabia. Other countries rely on crescent sighting or other tabulations, and their month may start one day earlier or later.
