Seasons beginning March 1
In Denmark, spring begins on March 1, while in Australia autumn begins on March 1. Meteorological spring in the Northern Hemisphere also begins on March 1; meteorological autumn in the Southern Hemisphere also begins on March 1.
Year beginning March 1
- Historically, March 1 was considered to be the beginning of the Roman 'work year'; The numerical Latin names of some months reflect this. (September = Seventh, October = Eighth, November = Ninth, December = Tenth). (see New Year).
If one begins each year on March 1, till the next March 1, then each date will have the same day number in this year, regardless of whether it is a leap year or not (e.g. December 25 is always day 300), unlike counting from January 1. This is due to the fact that the Gregorian and Julian calendars are based on the old Roman Calendar, which had March 1 as the first day of the year. The addition of the leap day of February 29 (which is what causes the days of leap years to fall on different day numbers) is a continuation of the February placement of the old Roman calendar's Mensis Intercalaris (a shortened extra month inserted to bring the 355 day long calendar into rough alignment with the seasons).
Also the months follow a regular 5-month cycle of 153 days, till the end of February. This can be seen by listing the number of days in the months thus:
Mar 31 Aug 31 Jan 31 Apr 30 Sep 30 Feb 28/29 May 31 Oct 31 Jun 30 Nov 30 Jul 31 Dec 31
This regularity is sometimes used in calendar calculations.
