Kylie Jenner’s Own Calendar Got Her Birthday Wrong

Kylie Jenner Announces Terry Richardson Calendar
Kylie Jenner is stripping down for a personalized calendar.

Kylie Jenner’s 20th birthday will be delayed by 10 days this year … because her own calendar couldn’t even get the date right.

The 2017 edition — sold exclusively on her website — lists her bday as August 20. Kylie was born on the 10th. On a positive note, there’s lots of cake … on Kylie.

The misprint isn’t just a one-off fluke either. We’re told it has appeared on multiple calendars since its release a couple weeks ago … possibly all of them.

See the hilarious mistake over at TMZ…
