Hi List,

Well I have a formula for figuring out what day of the week a particular 
date falls on.

1.  figure out how many years the desired date if forward or backward from 
the current year.
2.  Figure out the number of leap years between the current year and the 
desired year.
3.  Add the 2 results from step 1 and 2.
4.  Divide the result from step three by the number 7.
5.  If there is no remainder, then the day of the week that the desired date 
falls on is the same as that date in the current year.
6.  If there is a remainder, count the number of days forward or backwards 
(depending on whether your desire date is in the past or in the future) from 
the day the date falls on in the current year and that day of the week will 
be the day of the week on which the desired date falls in the desired year.

This method is sure to work back to 1682 for countries who adopted the 
Gregorian calendar in that year.  There is a way to go back further than 
1682, but I forget the additional steps.

Quite simple: I do it all the time in my head!

Hi there.

If you think my date figuring is interesting, just wait until next month, if
I remember it.
