Ramadan is not uniformly observed globally — the start date can vary by country or even be different mosque to mosque in the same city for a variety of reasons. But it all starts with a sighting of the crescent moon.

February 28 marks the 29th of Shaban. If the moon is sighted today, the first Roza will be on March 1; otherwise, fasting will begin on March 2.

The holy month of Ramadan will start on March 1 in Saudi Arabia with the sighting of a new crescent moon. In the Islamic calendar, a new month begins with the crescent moon, which is when the moon appears as a thin sliver.
