“Happy New Year” is probably the most well-known and intelligible congratulation on New Year’s Eve. Due to the fact that English is spoken worldwide, knowing this expression has become a normality. So if you are in another country on New Year’s Eve, where you do not know the language of the locals and think English is intelligible for them, then don’t hesitate to wish “Happy New Year” to everyone.
