Ramzan, the ninth month of the Islamic lunar calendar, is observed as a fasting period by Muslims who abstain from food and water from sunrise to sunset and it culminates in Eid-ul-Fitr celebrations.
The month honours the Angel Gabriel's revelation of the Koran, the holy scripture of Islam, to the Prophet Mohammed about 1,400 years ago.
During Ramadan, Muslims offer special prayers called Taraweeh at the end of their usual five-times prayers.
