I have synchronized the birthdays of my Contacts via Facebook (Hermes) and some of them with my Google Account (Exchange, but restored from a backup, so now only local). But when I look at my calendar all birthdays are 1 day too late (Birthday on 26 of October, shown is 27th of October), Does anybody know how to fix the issue or a workaround (except change birthdays of 200 contacts ) ?

Thanks

Robin
