As the HyWy and I were driving home this evening she pointed out something that I had never thought about: the purpose of New Year's celebration. It seems obvious, but why celebrate the new year? I'm not trying to rain on people's parade, but just trying to understand this a little more. The HyWy had a more philosophical point, which hopefully she can elaborate on or correct me on in the comments. However, I think her point was that the Western calender is not particularly rooted in any cosmic change (like the Lunar calender) so what is the significance of January 1? We both also agreed that if it wasn't for the presence of calenders then the passage of time would be minimally focused on. By demarcating a single day as the end of one measure of time and the start of another we also create an idea of past and future, which leads people to look to the future and look back upon the past. I have read articles about rural tribal cultures, which have no measure of time beyond the sunrise and sunset so when meeting someone they just wait at the appointed location (which sometimes works out to be several days). The mere idea of waiting at a location for someone for more than 1 hour is near appalling to most of us. Anyways back to my original point, which is in our current calender where did the significance of January 1 come from? My research has led me to conclude that January 1 was decreed the start of a new year during the rule of Caesar and the Romans. There are two reasons as I understand it: one corresponds to first day consuls would enter office and the second says that Caesar felt the start of the year should be in the month of January, which is named after the Roman god Janus. Janus, the god of doors and gates, had two faces, one facing forward and the other backward, and thus would be symbolic as we 'enter' a new year. Interestingly during the Middle Ages it seems that the start of the year corresponded to a major Christian date (birth of Christ, Easter, etc.), but William the Conqueror moved the date back to January 1. Ultimately the Gregorian calender was adopted by decree of Pope Gregory XIII (hence the name) and that differs slightly from the Julian Calender (of Julius Caesar, hence that name), but the both agree on the start of the year.
So after that slightly abbreviated history lesson I find it interesting that we celebrate a day, which is an arbitrary assignment for the start of the year to correspond with government officials taking their offices 2000+ years ago, a god in an ancient religion that is no longer practiced, and without any true significance to modern society.
