We would have a specific new year's day that wasn't a part of any other month, and a specific leap day that wouldn't occur in any specific month, either.

I propose a leap day to end some years, and a new year's day to start ever year.

Actually, no, what would be nicer would be a New Year's Eve and a possible leap day before it, which ends each year.
