Ramadan is the ninth month of the Islamic calendar where Muslims fast from dawn to sunset. It commemorates the first revelation of the Quran to Muhammad. The end of Ramadan is marked by the holiday of Eid al-Fitr, where Muslims celebrate fasting successfully for a month and are permitted to eat and drink during the day again. Eid al-Fitr falls on the first day of Shawwal after sighting the new crescent moon and involves special prayers, acts of charity, greeting others, and showing forgiveness.
