Is it Happy New Year or Happy New Year's?

Answer:
Happy New Year would be proper since it's a new year not new YEARS.

On the eve or the first day of the new year, wishing one a Happy New Year's Eve or Happy New Year's Day would be appropriate; however, if the eve or day isn't specified, Happy New Year is correct.
