Mawlid is the observance of the birthday of the Islamic prophet Muhammad.

Mawlid (Arabic: مَولِد النَّبِي‎ mawlidu n-nabiyyi, "Birth of the Prophet", sometimes simply called in colloquial Arabic مولد mawlid, mevlid, mevlit, mulud among other vernacular pronunciations; sometimes ميلاد mīlād) is the observance of the birthday of the Islamic prophet Muhammad which is celebrated often on the 12th day of Rabi' al-awwal, the third month in the Islamic calendar.

The 12th Day of Rabi' al-awwall is the most popular date from a list of many dates that are reported as the birth date.

The origin of Mawlid observance dates back to the period of the early four Rashidun Caliphs of Islam.

The celebration of this birthday was further initiated by the Fatimids and it was celebrated in lands under their control.
