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.
