[edit] 1900 date format
Please explain the "1900 date format". Is it something unique to Microsoft? — Joe Kress 19:40, 24 July 2005 (UTC)
- I have a related query. It says currently: In Microsoft Excel, the day 0 of the 1900 date format is January 0, 1900. However, as the fact that 1900 was not a leap year in the Gregorian calendar is ignored, it actually corresponds to 30 December 1899.
- Q.1 Why doesn't it correspond to 31 December 1899, being the day preceding 1 January 1900?
- Q.2 What does this have to do with leap years? Leap years only make their mark on 29 February, ie. 29 February 1900 in this case. How could this possibly affect dates in the preceding December/January? JackofOz 00:32, 1 December 2005 (UTC)
