It is new year's eve today. Tomorrow will bring about a whole new year for us to blunder through.
We use the Gregorian calender to keep track of time. The Gregorian calender is a far better alternative to the ones that we previously used. England (and all her colonies - including America at the time) switched over from the Julian calender to the Gregorian calender in 1752. To make this switch, the world lost 11 days. The good citizens went to bed on the evening of September 3rd and woke up the next morning on September 13th (except for those who were in the taverns - they had an 11 days and nights of carousing). Some of the more simple minded folks rioted in the street believing that the government had chopped 11 days off of their natural lives.
The Gegorian calender divides our time into 12 months which comprise a year. Since the world revolves around the sun at a rate of once every 365.242374 days, our years are 365 days long, except every fourth year, which is 366 days long UNLESS it's a year that is divisible by 100, in which case, the fourth year will only have 365 days UNLESS that year is divisible by 400, in which case the fourth year WILL have 366 days UNTIL the year 4000, which will only have 365 days. Pretty simple.
This all sounds very orderly, and it's designed to keep our equinoxes occuring at the same time very year. There is however a slight problem with the Gregorian calender though because as precise as it may seem, by the year 10,000 we will have gained a full day and our calenders will be one day behind.
This, however, will not be my problem.
Happy New Year everybody, best wishes for 2011 (which will have 365 calender days).
