Ramadan (Arabic: رَمَضَان, romanized: Ramaḍān; Hebrew: רמדאן; Turkish: Ramazan; Urdu: رمضان; Persian: رمضان; Malay: Ramadan) is the ninth month of the Islamic calendar, observed by Muslims worldwide as a month of fasting, prayer, reflection, and community. It is one of the Five Pillars of Islam and lasts twenty-nine to thirty days, from one sighting of the crescent moon to the next. During Ramadan, Muslims fast from dawn to sunset, abstaining from food, drink, smoking, and sexual activities. The fast is intended to teach self-discipline, self-restraint, and generosity while observing the holy month. The end of Ramadan is marked by the celebration of Eid al-Fitr, a festival of breaking the fast, which involves special prayers, feasting, and giving charity to the poor. Ramadan holds significant religious importance as it commemorates the month in which the Quran was first revealed to the Prophet Muhammad.
