The Islamic holy month of Ramadan will begin tomorrow in Saudi Arabia, the land of the religion's two holiest sites, authorities said.
The start date is set by both lunar calculations and physical sightings which determine when the last day of one lunar month ends and a new one begins.
Traditionally, many Muslim-majority countries have followed the dates set by Saudi religious authorities, but in recent years many have used their own astronomical calculations.
Ramadan is a holy month for the world's nearly 1.5 billion Muslims, many of whom practise the ritual of dawn-to-dusk fasting and prayers.
Tradition holds that it was during Ramadan that the Prophet Mohammed started receiving revelations of the Muslim holy book, the Koran.
Ramadan is one of the five "pillars" of Islam.
