Today is Patriot Day. Americans are asked to volunteer in their community and honor the victims of the 9/11 attacks.
On a much lighter note, it's also Odd Day, a day to marvel at the fact that this is one of only several days this century in which the date consists of three sequential odd numbers (09/11/13).
In honor of this kind of cool occasion, we've put together a roundup of other unusually numbered dates. Behold some of the bizarre days, both past and future, that make us say whoa!
November 11, 2011 – Sure, there were other similar dates (5/5/05, for example), but nothing drew more whoas than 11/11/11. A once-a-century phenomenon that takes place when all six digits of a date are identical. Bonus points to anybody who looked at the clock at 11:11. (Keanu rating: Four out of four whoas.)
July 8, 2009 – The date is pretty cool (7/8/9), but that's just the beginning. Those who had the foresight to check their watches at exactly 12:34:56 on 7/8/9 deserve extra special props. The moment lasted but a second, but the memories, like Bill and Ted's music, will last an eternity. (Three and a half whoas.)
March 14, 2015 – All the mathletes know that 3/14 is Pi Day. You can bet that these guys and gals are going to be extra excited on 3/14/15. Why? Go beyond the two decimal points, and it reads: 3.141592653. So, on 3/14/15 at 9:26:53 in the morning, expect a lot of cheers from your mathiest friends. (If you have a deep love of pi, 3.14 whoas. If you prefer pie, two and a half.)
October 12, 2014 – Who says Odd Todds have more fun? Even Stephens know how to party, too. On 10/12/14, we'll have the second-to-last Even Day of the century. Another will hit on 12/14/16. (Two and a half whoas. Even Day is like a Wyld Stallyns cover band. Nice, but we want the original.)
November 11, 2015 – Odd Day returns. If you forget to honor the occasion this year by using only words with an odd number of letters (not recommended), you can begin prepping your vocabulary for 2015. (Three and a third whoas.)
