   A doomsday device is a hypothetical construction — usually a weapon or weapons system — which could destroy all life on a planet, particularly Earth, or destroy the planet itself, bringing "doomsday", a term used for the end of planet Earth.

   Apr 26, 2020 · Doomsday method: Year code = 0, Century adjustment = 2, so Doomsday was a Tuesday in 1900. Closest Doomsday = Jan. 4 (since 2000 is a leap year), so January 30 (26 = 28 – 2 days later) was a Sunday.

   John Conway is a legendary mathematician who among his many achievements, devised a simple algorithm for figuring out in your head on what day of the week any calendar date would fall. He called it the Doomsday Rule.

   The "Doomsday" of the "Doomsday rule" is not about the end of the world. Every year has so called Doomsdays. A Doomsday is a day whose weekday is known. For every year the Doomsdays have the same weekday. For example: If you know that the November 7th (a Doomsday) was a Saturday - which weekday is November 21st? You know that there's 14 days in bet...

   The Doomsday rule takes advantage of the fact that patterns in calendars repeat every so often. Here's a basic diagram of what the algorithm is actually doing: It basically narrows down the weekday by first looking at the century given, then the year, then the month and finally pinponting the exact date. Let's go through it step-by-step. We'll try ...

   When I first heard about the Doomsday rule, I was baffled. It took me quite some time (and calculating) to understand it, but once I got it, I was amazed by its cleverness. The algorithm isn't too costly either, because it only uses algebra. With some more memory hooks (especially memorizing Doomsdays and anchor days for several years) one can calc...

   The Doomsday rule, Doomsday algorithm or Doomsday method is an algorithm of determination of the day of the week for a given date. It provides a perpetual calendar because the Gregorian calendar moves in cycles of 400 years.

   How to use doomsday device to calculate day of the week?

   • In order to show you how to use your Doomsday Device to calculate the day of the week of any given date, let us first try a simple worked example: Rotate the slotted discs to expose three numbers that add up to the year, 2134. That is, 2100 + 24 + 10. Other numbers might appear in two of the slots. They can be ignored.

   What is a doomsday example?

   • A Doomsday is a day whose weekday is known. For every year the Doomsdays have the same weekday. For example: If you know that the November 7th (a Doomsday) was a Saturday - which weekday is November 21st? You know that there's 14 days in between and you know that a week has 7 days - so it's 14 / 7 = 2.0 14/7 = 2.0 , so 2 whole weeks.

   How do you find the weekday of doomsdays?

   • To figure out the weekday of the Doomsdays of a given year (the so called "Anchor day"), we need to know the so called "Century Anchor day" first. This is the Anchor day of the first year of a given century. Those repeat in a 400 year cycle: If we calculate that back to the year 0, we get a Tuesday.

   Is Doomsday the last day of the week?

   • As a mnemonic for these, Conway suggests remembering that for January it’s the third day 3 years out of 4, and the fourth day every 4th year. And Doomsday is always the last day in February. Doomsday rule: Day of the week for Doomsday = Year Code + Century Adjustment (modulo 7)

   In any given year, there is one particular day of the week that is known as the Doomsday for that year. Our rst task is to determine which day this is. In 1900, Doomsday came on a Wednesday (= 3). Since 365 1 (mod 7), it follows that Doomsday moves forward one day per year, except that it moves forward by 2 days in a leap year. Thus in year
