›› Definition: Millennium

A millennium is a period of time equal to one thousand years. There are two main viewpoints about naming millennia and there was a popular debate leading up to the celebrations of the year 2000 as to whether 2000 was the beginning of a new millennium. Historically, there has been debate around the turn of the millennium, centuries and decades before.


›› Definition: Year

The mean tropical year is defined as the period of time for the mean ecliptic longitude of the Sun to increase by 360 degrees. Since the Sun's ecliptic longitude is measured with respect to the equinox, the tropical year comprises a complete cycle of the seasons; because of the biological and socio-economic importance of the seasons, the tropical year is the basis of most calendars.

The International Union of Pure and Applied Chemistry and the International Union of Geological Sciences have jointly recommended using defining the annus, with symbol a, as the length of the tropical year in the year 2000:

a = 31556925.445 seconds (approximately 365.24219265 ephemeris days)

We default to using the Gregorian year on this site, but you can select a specific type of year by entering the full name like "tropical year".
