iOS: Birthdays Calendar does not display Birthdays starting more than 77 Years ago
iCal, iOS 4, and MobileMe all offer a Birthdays Calendar. This calendar is automatically generated from birthday information found in your Address Book contacts. Contacts whose first birthday is more than 77 years ago do not display when viewed in the Birthdays Calendar on an iOS Device, such as an iPhone, iPod touch, or iPad.
The Birthdays Calendar can be synced via cable (USB) in iOS 4 or earlier versions. In iOS 4, the Birthday Calendar is available directly on the device, either from contacts stored on the iOS Device or synced with MobileMe. This issue occurs regardless of whether the Birthdays Calendar was created on the iOS Device or synced to it via MobileMe or iTunes.
