Today is the Last Sequential Date of the Century

Today, December 13, 2014, is the last day this century that the date as rendered by Americans will read in sequential order: 12/13/14.

The next time you’ll be able to write the date in the United States by simply counting up won’t come until January 2, 2103: 01/02/03. That’s 89 years from now—probably outside the lifespan of anyone reading this now but certainly a goal worth striving for. In any case, not to worry. Smithsonian has a nifty write up of upcoming dates of mathematical significance that some of us may yet live to experience.

In countries outside the U.S. where the date is rendered Day/Month/Year, this auspicious occasion passed last year on 11 December 2013: 11/12/13.
