Background

The Umm Al-Qura calendar is the lunar Hijri calendar officially adopted by Saudi Arabia for administrative purposes. It was originated from Umm Al-Qura newspaper, the official newspaper of government of Saudi Arabia. The newspaper is published weekly and its first issue was on Friday, 15 Jumada al-Ula 1343 AH (12 December 1924 CE). However, the calendar has been printed and distributed separately by the Saudi government since 1346 AH (1927 CE).

The calendar is widely used in Saudi Arabia, especially by the public sector. Official documents, political letters, health care records, and education certificates, are just examples of many other documents that are dated by the Hijri calendar.

However, the Gregorian calendar is the calendar used in most of the world, and it has been implemented as the default calendar in nearly every computer and database.
