Debate over millennium celebrations
There was a public debate leading up to the
celebrations of the year 2000 as to whether the beginning of that year should be understood as the beginning of the “new” millennium. Historically, there has been debate around the turn of previous decades, centuries, and millennia. The issue arises from the difference between the convention of using

The first convention is common in English-speaking countries, but the latter is favoured in, for example, Sweden (''tvåtusentalet'', which translates literally as the ''two thousands period'').
Those holding that the arrival of the new millennium should be celebrated in the transition from 2000 to 2001 (i.e., December 31, 2000, to January 1, 2001) argued that the

the first millennium BC was from the year 1000 BC to the end of the year 1 BC.

supported celebrating the arrival of the new millennium in the transition from 1999 to 2000 (i.e., December 31, 1999, to January 1, 2000), in that the change of the hundreds digit in the year number, with the zeroes rolling over, is consistent with the vernacular demarcation of decades by their 'tens' digit (e.g. naming the period 1980 to 1989 as "the

The start of the 21st century and 3rd millennium was
celebrated worldwide at the start of the year 2000. One year later, at the start of the year 2001, the celebrations had largely returned to the usual ringing in of just another new year, although some welcomed "the real millennium", including America's official timekeeper, the
