Early? Naw. It's already been next year for an hour and a half, in Vladivostok*. Another half hour, it'll be next year in Tokyo. So party already!
(Here, it's getting on toward sunrise Dec 31st, so there's plenty of partying time left. Or, for me, plenty of time to ignore all the partying.)
* The Russians are ahead of us!**
** We must not allow a New Year's gap!
