On This Day - December 31st 1999
Millennium celebrations are held around the world.
A millennium is a period of one thousand years. Because the Western calendar lacks a year numbered zero and begins instead with the year 1, there are two main viewpoints about naming millennia: whether each one begins on the year ending in '000' (e.g. the years 1000 and 2000) or whether the new millennium commences with the year ending in 001 (e.g. 1001, 2001). Australian Prime Minister John Howard made a point in favour of celebrating the millennium at the end of 2001, and was named "the party pooper of the century" by local newspapers.
Regardless of the semantic debate, the majority of millennium celebrations around the world were held on the evening of 31 December 1999. Celebrations began at 1000 GMT as the Chatham Islands, Tonga, Fiji and Kiribati experienced the new millennium first. The millennium arrived last of all in Samoa, 25 hours after arriving in Greenwich.
