You might find this discussion about "

New Years" interesting.

If you consider the new year as beginning at or around the Winter Solstice, then we probably start the new year about a week late. However, the point of leap years, leap seconds, and etc is to base the length of day on the rotation of the earth, so the sun is overhead at noon, and on the opposite side of the earth at midnight (not counting daylight savings time).

The year is based on the axial tilt of the planet, so that the solstices and equinoxes occur at the same time each year.

Our current

Gregorian Calendar is only a few centuries old, but it is very similar to the

Julian Calendar from 45 BC.

The primary problem with the Julian Calendar was an error in the number of leap years. According to Wikipedia, the two calendars are

out of sync by 13 days. The Russians Orthodox Christmas takes into account this shift in leap years, and considers Christmas to be on January 7, rather than December 25.

Anyway, by now we would be in 2014 in both the Gregorian and Julian Calendars.

Of course, the start date of 2014 years ago is arbitrary, and many other cultures have different years and start dates. See the list under the
