Ramadan is a Muslim religious observance that takes place during the ninth month of the Islamic calendar, believed to be the month in which the Qur'an began to be revealed. The name "Ramadan" is taken from the name of this month; the word itself derived from an Arabic word for intense heat, scorched ground, and shortness of rations. It is considered the most venerated and blessed month of the Islamic year. Prayers, sawm (fasting), charity, and self-accountability are especially stressed at this time; religious observances associated with Ramadan are kept throughout the month.

Laylat al-Qadr, which falls during the last third, commemorates the revelation of the first verses of the Qur'an and is considered the most holy night of the year. Ramadan ends with the holiday Eid ul-Fitr, on which feasts are held. During the month following Ramadan, called Shawwal, Muslims are encouraged to fast for a further six days.
