More than 1.9 billion Muslims around the world will mark the holy month, during which believers abstain from eating, drinking and smoking from dawn until sunset.

Saudi Arabia has announced that Ramazan will start on Thursday after the moon was not sighted on Tuesday.

Saudi Arabia’s supreme court ruled on Tuesday evening that Shaban will end on Wednesday, meaning Ramazan will begin the following day, the official Saudi Press Agency reported.

The official Crescent Sighting Committee in neighbouring Qatar also announced Thursday as the first day of Ramazan, the official Qatar News Agency said on Twitter.

 Saudi Arabia’s King Salman on Tuesday sent his best wishes for Ramadan to citizens of the Kingdom and Muslims everywhere, expressing his hope that the holy month will bring hope and peace to Muslims and the entire world.

He instructed authorities involved in providing services for visitors to the Two Holy Mosques to continue to work with the highest levels of efficiency and excellence to ensure that pilgrims can perform their rituals with ease and tranquility, the Saudi press Agency reported.

The king was speaking as he chaired the weekly Cabinet session at Irqah Palace in Riyadh, after the Supreme Court announced that Ramadan would begin on Thursday.
