Ramadan is the ninth month of the Islamic lunar calendar during which Muslims fast from dawn to sunset. Fasting is one of the five pillars of Islam and involves abstaining from food, drink, and other pleasures. The start and end dates of Ramadan shift each year based on the lunar calendar. During this month, Muslims prepare spiritually through prayer and good deeds. Fasting is meant to bring humility and draw people closer to Allah through self-control and reflection on faith.
