It is observed annually after the sighting of the new moon and lasts for 29 or 30 days until the next new moon appears. The observance is regarded as one of the five pillars of Islam along with belief, worship, charitable donation and the pilgrimage to Mecca.
The Muslim holy book explains: "The month of Ramadan in which was revealed the Koran, a guidance for mankind and clear proofs for the guidance and the criterion [between right and wrong]."
Ramadan concludes with Eid ul-Fitr, when morning prayers are followed by feasting and celebrations.
