I have an HTC Desire and a Mac (10.6, if that matters) and I sync them via Google Contacts.

Many of my contacts in Apple's Address Book.app have a birthday set, but it does not transfer to Google Contacts and thus not to my Android Contacts.

If I create a new contact on Google Mail/Contacts and set a birthday, it is immediately synced to my Android phone, complete with birthday, but in Address Book.app the birthday is missing.

How can I get my birthdays in sync?

If a proper sync is not possible, it would be nice to have at least a calendar that is synced, but I don't know how to add the calendar that Address Book.app can generate automatically to my Google account to sync.

I have seen icalbirthdays but I don't think it can help me. I would like to avoid kludges like creating a calender from Address Book in iCal, publishing that to a third server and subscribing in Google Calendar...)

  • That's a tricky one. You say you sync Address Book with Google Contacts. How are you doing that? The setting in Address Book itself?

  • You might also want to consider asking on apple.stackexchange.com as this is also a Mac related question

  • @Al: Yes, I use the sync provided in Address Book: Accounts, "Synchronize with Google". @Bryan: thanks for the suggestion

Okay, I am admittedly not an Apple guy, but it looks like you might need a third-party solution.

According to some comments I found here, non-support of birthdays is a known thorn. To get around it, the commenter used Spanning Sync but also mentioned SyncMan.

Spanning Sync offers a 15-day trial, after which it costs $25 for a one-year subscription or a $65 one-time purchase. The commenter referenced above did mention that he chose this because birthdays were not being sync'd.

SyncMan offers a 30-day trial, after which you can purchase it for $14.99. On the support page it specifically mentions birthdays as one of the things it syncs that the native Google sync in Address Book doesn't.


I personally used Missing Sync, it's quite a good app for Mac
