Ramadan is the holiest month for Muslims. Every year, Muslims round the world fast during daylight hours.
Ramadan is the ninth month in the Muslim lunar calendar. Healthy adult Muslims fast in Ramadan from dawn until dusk. This includes abstaining from drinking, eating, immoral acts and anger. Other acts of worship such as prayer, reading the Quran and charity are also encouraged during the holy month. Muslims also believe the Quran was revealed in Ramadan.
Since Ramadan is part of the lunar calendar, its date annually changes on the Gregorian calendar. Muslims tend to wait for the new month's moon to appear before they announce the first day of Ramadan. However, they can still estimate the day beforehand.
Fasting is one of the five pillars of Islam. There is also a verse in the Quran that prescribes fasting for all Muslims who are mature and healthy enough to do so for the full day.
So Muslims fast as an act of worship, a chance to get closer to God, and a way to become more compassionate to those in need. Fasting is also seen as a way to learn patience and break bad habits.
Lunar months last between 29 to 30 days depending on when the new moon is sighted. If the moon is not seen on the night of the 29th day, then Ramadan lasts for the full 30 days.
The Eid al-Fitr celebration marks the end of the month when Muslims celebrate a successful Ramadan of fasting and worship.
