Why do I have duplicate contact birthdays on Android calendar? I deleted all of my contacts from Google and from my HTC incredible so that I could reload them all in just Google. As a result, the calendar on my phone has 2 entries on the "contacts birthdays and events" calendar on my phone. The calendar in my Google account only has 1 entry. The android calendar even has a birthday for a contact I deleted.

Has anyone else seen this and have a fix?

Hey Guys,

I had to clear the Calendar Data for the Bday to show on my calendar. This is what I did,
Go to Settings-Applications-Manage applications, then select Calendar Storage then "delete data". After doing this the screen (HTC EVO) will reboot (white screen with the HTC Logo).

After clearing the data, go to the calendar setting and add the Bbay.

Hope this work for you.
