Many happy returns!

[From http://en.wikipedia.org/wiki/Many_Happy_Returns_(greeting):

Many Happy Returns is a greeting which is usually reserved for birthdays. It is more common in British English than in American English.

The term itself refers to the passing year. Since the 18th century this has been used as a salutation to offer the hope that a happy day being marked would recur many more times. It is now primarily used on birthdays; prior to the mid 19th century it was used more generally, at any celebratory or festive event.

Current usage is often as a more formal option than 'Happy Birthday'. It is also often to be found on greetings cards.]
