The Umm Al-Qura calendar has been issued in three different versions since its founding by the King Abdulaziz Center for Science and Technology. As a result, different information appears in some systems. Some events, such as birth and death, were recorded in different calendars over the past sixty years, and the difference appears upon research.

This program updates the type of Umm al-Qura calendar used, whether it is Q1, Q2, Q3, and with it you can know exactly what date corresponds to any other international calendar.
