Why is 1 January the day of the year we celebrate the beginning of a new year?

Send us Fan MailWho came up with celebrating the new year on 1 January?   Well, for every person who listens to this, it's always been 1 January, but why that day?  Not a historian by any means, but dating back to some 2000 BC and even further back for the Chinese, the beginning of a new year has gone through a few changes which means it's been tossed around a bit from century to century as to when a culture and/or a society decided to celebrate a new year.Leave to the Brintons to mess with it and have a period with two different dates on documents.None of these matters.  Have a blessed and happy new year.
