mil-len-ni-um (n). A span of one thousand years.

According to the United States Naval Observatory, the nation's official time keeper, the end of the second millennium and the beginning of the third will be reached on January 1, 2001. This date is based on a calendar created in Rome, in 526 Anno Domini (A.D.), now recognized globally. Rather than starting with the year zero, the calendar begins with the date January 1, 1 A.D. Consequently, the next millennium is not officially reached until January 1, 2001. Despite this fact, much of the world is planning to celebrate on December 31, 1999, when the calendars flips to the year 2000.

During the millennium year (January 1, 2000 to January 1, 2001), the White House will lead a national Millennium Program that will engage Americans in a wide variety of activities and initiatives designed to highlight our heritage and celebrate our creativity. Visit this countdown clock to see the time remaining to the year's start.
