Background: The issue date of the Egyptian stamp (16 September 1994 in the Gregorian calendar) corresponds to Friday 10 Rabī’ al-Thānī 1415 A.H. in the Hijri or Islamic calendar (Anno Hijri or AH). The Islamic (Hijri) year consists of twelve (purely lunar) months; Rabī’ al-Thānī is the fourth month of the Islamic calendar.

The Islamic calendar or Muslim calendar or Hijri calendar is a lunar calendar based on 12 lunar months in a year of 354 or 355 days, used to date events in many Muslim countries (concurrently with the Gregorian calendar), and used by Muslims everywhere to determine the proper day on which to celebrate Islamic holydays and festivals. Its first year was the moon year during which the Hijra, i.e. the emigration of the Islamic prophet Muhammad from Mecca to Medina, occurred. Each numbered year is designated either H for Hijra or AH for the Latin anno Hegirae (in the year of the Hijra). A limited number of years before Hijra (BH) are used to date events related to Islam, such as the birth of Muhammad in 53 BH.

According to calculations, the Hijra corresponded to Friday 16 July 622 (even though the actual emigration took place in September). Because of the Hijra event, the calendar was named the Hijri calendar.
