I'd go with Christmas here. It's warm and sunny, backyard cricket, catching up with the family, no other holiday beats it (apart from birthday, maybe, but that wasn't in the poll). I have no idea what Hanuaka is (the Jewish Christmas?), Halloween and Thanksgiving aren't celebrated in Australia, Easter is a hassle as my family is Catholic (and I am not) so I'm usually dragged down to church, and for the past two New Years I've either been working or grounded, so no fun there.
