(Latin: "in the year of the world
") abbreviated as AM
, refers to a Calendar era
counting from the Biblical creation
of the world.
Years in the Hebrew calendar
are counted from the Creation year
. The system in use today was adopted sometime before 3925 AM
(165 CE), and based on the calculation in the Seder Olam Rabbah
of Rabbi Yose Ben Halafta
in about 160 CE. By his calculation first humans
were created in the year 3761 BCE
. The Jewish year spanning 2008–2009 CE, after Rosh Hashanah
, is 5769 AM
in the Hebrew calendar.
AM was also used by early Christian
chronographers. The medieval historian Bede
dated creation to 18 March 3952 BCE
. The Chronicon of Eusebius
dated creation to the year of 5199 BCE
. Earlier editions of the Roman Martyrology
for Christmas Day
used this date, as did the Irish Annals of the Four Masters
The Etos Kosmou is the corresponding concept in the Byzantine calendar, which dates creation to 1 September 5509 BCE.
James Ussher (1654) dated creation to 23 October 4004 BCE according to the Julian Calendar, which in the Gregorian Calendar would be 21 September 4004 BCE.
Related to this is the Freemasonry's Anno Lucis, which adds 4000 years to the CE date.
