Saudis use a telescope to monitor the new moon of Ramadan as astronomers and scholars of Islam debate when the holy Muslim month of Ramadan begins, in the Saudi city of Taif on Thursday, July 19. The start of the fasting month, when the faithful abstain from eating from dawn to sunset, is determined by the sighting of the new moon.
On the eve of Ramadan, astronomers and scholars consult the sky to determine the precise starting date. Since the Muslim holy month starts at the sighting of the new moon, the exact date is not known far in advance. This has caused issues for some European Muslims. Jordanians begin Ramadan on Friday, while Muslims in the West Bank began Thursday.

Ramadan begins around 11 days earlier each year. Its start is calculated based on the sighting of the new moon, which marks the beginning of the Muslim lunar month that varies between 29 or 30 days.
