A millennium (plural millennia) is a period of time equal to one thousand years (1,000)—from the Latin phrase mille, thousand, and annus, year—often but not necessarily related numerically to a particular dating system.
For example, a millennium could start at the beginning of the year 289 and finish at the beginning of the year 1289.
Sometimes, it is used specifically for periods of one thousand years that begin at the starting point (initial reference point) of the calendar in consideration (typically the year "1"), or in later years which are whole number multiples of a thousand years after it. The term can also refer to an interval of time beginning on any date. Frequently in the latter case (and sometimes also in the former) it may have religious or theological implications (see millenarianism). Sometimes in religious use, such an interval called a "millennium" might be interpreted less precisely, i.e., not always being exactly 1000 years long.
