Dates for Math Lovers

If you ever find yourself making wishes when the clock hits 11:11 or 12:34, you may want to take notice of 13 December 2014 (12/13/14), as it’s the last sequential calendar date of the 21st century. After that, we’ll have to wait another 89 years until we can revel in the nonsensical wonder of the next sequential occurrence on 2 January 2103. Luckily, Smithsonian Magazine has compiled a list of other upcoming numerical arrangements to celebrate for those of us who can’t wait (or won’t be here) for 01/02/03.
