Doomsday

Given a random date, can you determine the weekday of that date? Conway's Doomsday rule provides a simple set of steps to calculate the weekday of any date in the Gregorian calendar. This tool will help you practice the algorithm by giving you random dates to test on. Set this as your homepage to get yourself to practice this every day.
