Wrong day for birthday shown in Contacts linked to Facebook

[tokuzumi]

I was noticing the day of the week is wrong with my contacts birthdays that are linked with facebook accounts. One friend has a b-day today, and it shows Tuesday, Feb 24 (should be Wednesday). Another friend has a b-day of Sun, July 14, when it should be a Wednesday. Finally, I see another friend with a b-day of Friday, April 27, when the 27th is a Tuesday. The facebook app on the phone just displays the date, not the day of the week, which leads me to believe the contacts app is getting the day of the week messed up. My calendar displays the correct month/year.

Edit: I'm stock, non-rooted, by the way
