Unless you know all the dates in the set are from the same year.
Sure, but no such assumption was stated by the OP. An equally valid assumption would be "next occurrence" of the given dates - one might for instance have to order dates for soccer matches of the coming season.

My meta point of course is that if people post problems here, they shouldn't hide essential knowledge about the problem (I do assume the OP knows which years the dates are supposed to have).

In reply to Re^3: sort based on date by JavaFan
