JavaScript Tutorial 12 Doomsday Algorithm

Video Sponsor : [ Free AI, Crypto, & Cybersecurity Videos ]

In this part I continue my JavaScript Tutorial and cover the Doomsday Algorithm. I’ll make a JavaScript app that can find the weekday for and date in history and display the steps.

John Conway discovered the Doomsday Rule. He realized that certain dates in every year all share the same week day. If you can then calculate what each years Doomsday is you can then easily find any weekday for any date.

With a little practice you can perform these calculations in your head and then amaze your friends. I made this JavaScript app to help you practice while at the same time learn more about making fun JavaScript apps.
