Doomsday for 2017 is Tuesday
January 3, 2017
Today, January 3, 2017, is January's "Doomsday" — and it's a Tuesday.
What does this mean?
Well, January's Doomsday is either the 3rd or the 4th, depending on whether it's a normal year (when it's the 3rd), or a leap year (when it's the 4th). So, because 2017 is not a leap year, it's January 3rd, and 2017's Doomsday day of the week is Tuesday.
This, of course, means that February 28, the last day of February, is also Tuesday.
But what does all this mean? What is a Doomsday, anyway?
For one thing, knowing that Doomsday for 2017 is Tuesday tells you immediately that April 4th, June 6th, August 8th, October 10th, and December 12th are also all on a Tuesday this year. Amazing, isn't it?
