Happy new year means Frohes neues Jahr in German.

On a Party, when midnight has come and everyone's clinking glasses and hugging, it's common to say "Frohes Neues!" (short form of Frohes Neues Jahr) or "Prost Neujahr!" (Prost = Cheers, Neujahr = New Year's Day).

The more common translation of Happy New Year is Glückliches Neues Jahr
Glückliches Neujahr!
you would say:(this might be hard to read) glücklich neue Jahr meinen Freunden.
