Steph: Is it “New Years” or “New Year’s”?
It will be my title for a collection of poems about a new year’s party.

is it “new years” (no apostrophe) or “new year’s”?

thanks! =]
there’s not going to be any “party” in the title..?

I’d say it’s new year’s party because the party belongs to the new year.
