Determine the day of the week for any date

There are two modules in this distribution. DateDoomsday calculates doomsday for a particular year. DateDayOfWeek uses the doomsday algorithm to calculate the day of the week for any given date.

Doomsday is a cute little idea invented by Dr John Conway that makes it very easy to figure out the day of the week for any date.

For more information about the origins and mathematics surrounding doomsday, see the following web sites
