Kylie Jenner's Official Kylie Jenner 2017 Calendar is a hot item for Kylie merch kollectors, any fans of a butt and a boa constrictor hanging out together, those in the market for some important-date-marking wank material and anyone willing to look past calendar photographer Terry Richardson's deeply problematic history of alleged sexual harassment on the job. It is not, however, a good way to keep track of when Kylie's birthday is, because as TMZ points out, the date is off by ten days on her official calendar.

As any true Kylie fan knows, Kylie Kristen Jenner was born on August 10, 1997. But in the August pages of Kylie's official calendar — decorated with a photo of the cosmetics mogul and reality star mostly nude and covered in strategically-placed cake — it says "Kylie's Birthday" on August 20, with "20 today!" written in what's supposed to be Kylie's handwriting. Oops.

Given that Kylie is just one woman, it's not surprising that she outsourced the layout of her calendar and all its important dates to a secondary party. But one would think a klose Kylie kompatriot — such as her assistantVictoria Villarroel, or hands-on Kardashian-Jenner matriarch Kris Jenner — would have caught what so many sets of eyes apparently missed?

Kylie's fans definitely caught the error when they received their calendars. Check out some reactions below — maybe a reprint will fix the error by the time you order yours on Kylie's website (please note that "all sales are final").
