Note about Global Islamic Calendar

The global islamic calender is calculated based on global crescent moon sighting probability in the beginning of each islamic months. It is based on the general direction given by the Prophet Muhammad (peace be upon him) to begin and end islamic months by sighting the crescent moon (hilal). Since the direction was addressed to the whole ummah, then a sighting of the crescent moon in one location, any where on earth, within one particular day, is sufficient to start the new islamic month.

Following this general direction is the only way in formulating a global islamic calendar that can unite the whole muslim populations around the world. Following local moonsighting, on the other hand, will never unite the whole muslim ummah, since there will always be regions where the crescent moon will not be visible on the day it will be visible in other regions.

Technically, the global sighting probability of the crescent moon on particular day is calculated based on the works by scientists and astronomers that studied and collected reliable crescent moon sighting reports from around the world, such as Yallop (1997) and Odeh (2006). The calculations can be visualised as crescent moon visibility maps that show which regions or countries on earth that can see the new crescent moon on particular evening (such as those displayed above). The HilalMap service in this website is dedicated in generating and displaying such crescent moon visibility maps that are useful in determining the beginning of islamic months.

The global islamic calendar dates displayed in this website is based on the following simple rule:

This rule ensures that the calculated beginnings of the islamic month is always accompanied by positive hilal or crescent moon sighting reports from some muslims around the world on the preceding evening of the respective months.
