Frequently asked questions
When does Rabi' al-Thani 1400 AH start?
Rabi' al-Thani 1400 AH starts on February 18, 1980 (Monday) 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.
