The Abu Dhabi-based International Astronomical Centre predicted most Islamic countries will begin the holy month of Ramadan on March 1.
The Director of the Centre, Mohammed Shawkat Odeh, said the crescent may be visible by telescope in some parts of the Islamic world on February 28.
Given that the conjunction occurs before sunset and the moon sets after sunset in all Islamic regions, it is expected that most Islamic countries will declare March 1 the first day of Ramadan.
The UAE is awaiting official confirmation on the start date of Ramadan by the moon-sighting committee.
