Calendar error after upgrading to iOS 5

Loved the design of the app and how its different from other calendar apps. However, it became unusable after the iOS 5 update, because it apparently skips two days, so all my schedule is messed up. (It shows me that Oct. 20 is a Saturday instead of Thursday.)
