Use this if you want to know what day of the week it was/will be a certain date.

The program is based on mathematics, NOT a yearbook...

It uses the Gregorian calendar, which is correct from about year 1500 A.D in Catholic nations, (with others nations using it a couple of decades later) untill now.

It does, though, have to be corrected with one day about each 4000 years - meaning this program might be incorrect for dates after about 5000 A.D

For the interested one: there is a leap year every 4:th year except every 100:th year, but every 400:th year it will be leap year anyway.
That is why 2000 was a leap year, while 2100 won't be.
