Quiz Yourself on John Conway's Doomsday Rule

The Numberphile podcast on legendary mathematician John Conway talks about his ability to figure out which day of the week any date you give him falls on. He trained himself by having his computer quiz him on a number of random dates whenever he logged in. Conway was able to perform this calculation in only 2 seconds.  The method for working out which day of the week any date in the Gregorian calendar falls on is known as the Doomsday rule.


I programmed the Doomday rule using MicroPython on a TinyPICO. It uses my modified HT16K33 module to display random dates challenging you to guess on what day of the week they fall.
