Ramadan (Arabic: رمضان Ramaḍān, Arabic pronunciation: [rɑmɑd̪ˤɑːn]) (also written Ramazan, Ramzan, Ramadhan, Ramdan, Ramadaan) is the ninth month of the Islamic calendar. It is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking, that is in excess or ill-natured; from dawn until sunset. Fasting is meant to teach the Muslim patience, modesty and spirituality. Ramadan is a time for Muslims to fast for the sake of God (Arabic: الله, trans: Allah) and to offer more prayer than usual. During Ramadan, Muslims ask forgiveness for past sins, pray for guidance and help in refraining from everyday evils, and try to purify themselves through self-restraint and good deeds. As compared to the solar calendar, the dates of Ramadan vary, moving backwards about ten days each year as it is a moving holiday depending on the moon. Ramadan was the month in which the first verses of the Qur'an were said to be revealed to the Islamic Prophet Muhammad.
