Day of Year
Day of Month
Month Names
Month Numbers
Leap year


Each day is labeled with the day-of-the-year as well as the day-of-the-month. This helps when you use the the ISO-8601 standard http://www.ft.uni-erlangen.de/~mskuhn/iso-time.html . For example, the 2 standard formats for Monday, March 3, 2000 A.D. are:

	2000-061
	2000-03-03
.

Royal Greenwich Observatory http://www.ast.cam.ac.uk/RGO/leaflets/leapyear/leapyear.html which would appear to be the authoritative reference on calendars, says "Pope Gregory XIII, in 1582, instituted the Gregorian calendar, which has been used since then. ... 1800 and 1900 are not leap-years whereas 2000 will be."

2000/01/01 THE YEAR 2000 starts. Saturday. 2000/02/29 leap day 2000/12/31 366th day of year.

an example of a nice calendar with both day-of-year and days-remaining-in-year (Jan 1 is day 1/364) (Dec 31 is labeled 364/1). http://pgh.nauticom.net/cgi-bin/execute/babylon/webcal.pl/

day of the week http://www.geocities.com/SiliconValley/2499/code.html has 2 nifty procedures for calculating the day-of-week for any year-month-day, one for humans (in your head, without paper), and one for machines.
