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](http://www.smithsonianmag.com/science-nature/last-sequential-date-century-121314-fun-math-lovers-180953413/?no-ist) 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. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3632688/sequential-date-century/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3632688/sequential-date-century/"},"headline":"Today is the Last Sequential Date of the Century","datePublished":"2014-12-13T15:52:57.000Z","dateModified":"2026-04-13T07:15:18.329Z","description":"12/13/14.
