The Doomsday rule

BrownStudies explains the Doomsday rule, a nifty way to figure out the day of the week for a given date. Such stuff holds an irresistible appeal for the ten-year-old secret agent in me. Because say you were like stuck on a desert island or something, and you didn’t have a calendar, and you needed to figure out the day of the week that something was going to happen — well, you get the idea.

Last night I challenged my spouse to test me: pick a date, any date. And yes, June 23, 2014, falls on a Monday. It’s the rule.
