Full description

Hijri lunar astronomical calendar for the Qatif Governorate located on the coordinates: 26.57675445 North 49.90406705 East And 8 meters above sea level. The calendar is one of the outputs of the Crescents Calendar, one of the sections of the al-Mustafa astronomical program programmed by Abu Hadi. It relies on the famous Yallop criterion for Dr. Bernard Yallop in calculating the entry of months. We seek with the help of God Almighty to make the calendar as close to the legal calendar as possible, as the calendar may not be compatible with some of the legal new months according to the sighting of the crescent with the naked eye, and the inconsistency may not exceed one month per year, if any.
