Anno Mundi
Anno Mundi (AM, "in the year of the world") refers to a Calendar era counting from the creation of the world. An example is the Hebrew calendar which considers creation to have taken place in the year 3760 BC. Thus, as it is after Rosh Hashanah, the Hebrew calendar calls the current year 5767 AM.
AM was also used by early Christian chronographers. The medieval historian Bede dated creation to 18 March 3952 BC.
The Aetos Kosmou is the corresponding concept in the Byzantine Greek Calendar, which dates creation to 1 September, 5509 BC.
James Ussher (1654) dated creation to 23 October, 4004 BC.
Related to this is the Anno Lucis of Freemasonry, which adds 4000 years to the AD date; and the Julian day number, counting the days that have elapsed since noon Greenwich Mean Time (UT or TT) on Monday, January 1, 4713 BC.
The date inferred from the Roman Martyrology [1] is 25 March, 5198 BC.
