The most common calendar used internationally today is the Gregorian calendar, which is Pope Gregory XIII's 1582 reform of the Julian calendar. Some non-Christian countries use the Gregorian calendar for civil and/or international purposes and another calendar for religious/ internal use. This is because (a) the Gregorian calendar is considered a Christian calendar, since the numbering of its years is based on the wrongly calculated year of the birth of Jesus, and (b) many festivals are based on the phases of the moon, and the Gregorian is neither a lunar calendar, like the Islamic Hijra, nor a lunisolar calendar, like the Hebrew Luach.
