Anno MundiAnno Mundi (from Latin "in the year of the world"; Livryat haOlam), abbreviated as AM or A.M., or Year After Creation, is a calendar era based on the biblical accounts of the creation of the world and subsequent history. Two such calendar eras have seen notable use historically: Since the Middle Ages, the Hebrew calendar has been based on rabbinic calculations of the year of creation from the Hebrew Masoretic Text of the Bible. This calendar is used within Jewish communities for religious purposes and is one of two official calendars in Israel.
Genealogies of GenesisThe genealogies of Genesis provide the framework around which the Book of Genesis is structured. Beginning with Adam, genealogical material in Genesis 4, 5, 10, 11, 22, 25, 29–30, 35–36, and 46 moves the narrative forward from the creation to the beginnings of the Israelites' existence as a people. Adam's lineage in Genesis contains two branches: Chapter 4 giving the descendants of for Cain, and Chapter 5 that for Seth that is then continued in later chapters.
Young Earth creationismYoung Earth creationism (YEC) is a form of creationism which holds as a central tenet that the Earth and its lifeforms were created by supernatural acts of the Abrahamic God between approximately 6,000 and 10,000 years ago. In its most widespread version, YEC is based on the religious belief in the inerrancy of certain literal interpretations of the Book of Genesis. Its primary adherents are Christians and Jews who believe that God created the Earth in six literal days.
ChronologyChronology (from Latin chronologia, from Ancient Greek χρόνος, chrónos, "time"; and -λογία, -logia) is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events". Chronology is a part of periodization. It is also a part of the discipline of history including earth history, the earth sciences, and study of the geologic time scale.
Ussher chronologyThe Ussher chronology is a 17th-century chronology of the history of the world formulated from a literal reading of the Old Testament by James Ussher, the Archbishop of Armagh and Primate of All Ireland. The chronology is sometimes associated with young Earth creationism, which holds that the universe was created only a few millennia ago by God as described in the first two chapters of the biblical book of Genesis. Ussher's work fell into disrepute in the 19th century.
Anno DominiThe terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord" but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ". The form "BC" is specific to English, and equivalent abbreviations are used in other languages: the Latin form, rarely used in English, is Ante Christum natum (ACN) or Ante Christum (AC).
Hebrew calendarThe Hebrew calendar (הַלּוּחַ הָעִבְרִי), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel. It determines the dates for Jewish holidays and the appropriate public reading of Torah portions, yahrzeits (dates to commemorate the death of a relative), and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside the Gregorian calendar.
