Ramadan is an Islamic religious observance of the ninth month of the Islamic lunar calendar. It begins with the sight of the new moon and continues for about 30 days. For Muslims, Ramadan is considered the holiest month of the Islamic year.

Across the world, Muslims fast each day for the entire month of Ramadan, abstaining from food and drink from dawn to dusk. That means around 15 hours without food, water, cigarettes or caffeine.

Fasting is aimed at drawing worshippers closer to God through self-control, remembrance and humility. The challenge of fasting for many is also a chance to reset spiritually and physically, kick bad habits and purify the heart.

During the day, Muslims must also abstain from sex, gossip and cursing, and are encouraged to focus on meditative acts like prayer, reading the Quran and charity.
