RIYADH: The crescent moon was not sighted on Tuesday evening in Saudi Arabia and Thursday, March 23, will be the start of the holy month of Ramadan, the Kingdom’s Supreme Court has said.  The court called on all Muslims in the Kingdom to look for the Ramadan crescent on Tuesday evening that corresponds to Shaban 29, 1444. The Ministry of Justice announced it has launched an electronic system for crescent sighting “with the aim of automating and governing the moon sighting processes, and unifying work procedures between the courts of first instance and the Supreme Court.”  The service aims to unify the data source of the observatory through a robust electronic system that provides speed and integration with the relevant authorities, raising the quality of the observatory operations, and speeding up the issuance of the Supreme Court’s decision regarding new moon sightings. 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.
