millennium (redirected from millennially)

millennium [Lat.,=1,000 years], the period of 1,000 years in which, according to some schools of Christian eschatology, Christ will reign again gloriously on earth. Belief in the millennium, based on Rev. 20, has recurred in Christianity since the earliest times. Today it is held and taught by the Adventists and some other conservative evangelical bodies. Belief in the millennium is called chiliasm by historians of the ancient church. See Judgment Day.

millennium

Period of 1,000 years. The Gregorian calendar, put forth in 1582 and subsequently adopted by most countries, did not include a year 0 in the transition from BC (years before Christ) to AD (those since his birth). Thus, the 1st millennium is defined as spanning years 1–1000 and the 2nd years 1001–2000. Although numerous popular celebrations marked the start of the year 2000, the 21st century and 3rd millennium AD began on Jan. 1, 2001.
