millennium

Time period of 1000 years

A millennium is a period of one thousand years, sometimes called a kiloannum (ka), or kiloyear (ky). Sometimes, the word is used specifically for periods of a thousand years that begin at the starting point of the calendar in consideration and at later years that are whole number multiples of a thousand years after the start point. The term can also refer to an interval of time beginning on any date. Millennia sometimes have religious or theological implications.
