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.
Common EraCommon Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year.
AlexandriaAlexandria (ˌælᵻɡˈzændriə,_-ˈzɑːn- ; الإسكندرية; Ἀλεξάνδρεια) is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in 331 BC by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. Called the "Bride of the Mediterranean" internationally, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez.
BedeBede (biːd Bǣda ˈbæːdɑ, Bēda ˈbeːdɑ; 672/3 - 26 May 735) was an English monk and an author and scholar. He was one of the greatest teachers and writers during the Early Middle Ages, and his most famous work, Ecclesiastical History of the English People, gained him the title "The Father of English History". He served at the monastery of St Peter and its companion monastery of St Paul in the Kingdom of Northumbria of the Angles. He is also known as Saint Bede, The Venerable Bede, and Bede the Venerable (Beda Venerabilis).
JesuitsThe Society of Jesus (Societas Iesu; abbreviation: SJ), also known as the Jesuit Order or the Jesuits (ˈdʒɛʒu.ɪts,_ˈdʒɛz(j)u,_ˈdʒɛs-; Iesuitæ), is a religious order of clerics regular of pontifical right for men in the Catholic Church headquartered in Rome. It was founded in 1540 by Ignatius of Loyola and six companions, with the approval of Pope Paul III. The society is engaged in evangelization and apostolic ministry in 112 nations. Jesuits work in education, research, and cultural pursuits.
Holocene calendarThe Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans shifted from a hunter-gatherer lifestyle to agriculture and fixed settlements. The current year by the Gregorian calendar, AD , is HE in the Holocene calendar.
Byzantine calendarThe Byzantine calendar, also called the Roman calendar, the Creation Era of Constantinople or the Era of the World (Ἔτη Γενέσεως Κόσμου κατὰ Ῥωμαίους, also Ἔτος Κτίσεως Κόσμου or Ἔτος Κόσμου, abbreviated as ε.Κ.; literal translation of Ancient Greek Roman year since the creation of the universe), was the calendar used by the Eastern Orthodox Church from c. 691 to 1728 in the Ecumenical Patriarchate. It was also the official calendar of the Byzantine Empire from 988 to 1453 and of Kievan Rus' and Russia from c.
Date of EasterAs a moveable feast, the date of Easter is determined in each year through a calculation known as computus. Easter is celebrated on the first Sunday after the Paschal full moon, which is the first full moon on or after 21 March (a fixed approximation of the March equinox). Determining this date in advance requires a correlation between the lunar months and the solar year, while also accounting for the month, date, and weekday of the Julian or Gregorian calendar.
Before PresentBefore Present (BP) years, also known as "time before present" or "years before present (YBP)", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale.
Regnal yearA regnal year is a year of the reign of a sovereign, from the Latin regnum meaning kingdom, rule. Regnal years considered the date as an ordinal, not a cardinal number. For example, a monarch could have a first year of rule, a second year of rule, a third year of rule, and so on, but not a zeroth year of rule. Applying this ancient epoch system to modern calculations of time, which include zero, is what led to the debate over when the third millennium began.
