In the United States people bang pots and pans together when Midnight comes to signal the new year. It's REALLY annoying! I don't know if anyone else does that in other countries though.

Hey Jimmy. In my state India, we don't celebrate new year except in cities. In cities on 31th night people gather with music and dance.

Hey, Jimmy! I'm Mario, from Brazil! Here we celebrate the New Year's Eve in a very contagious form, with great joy. Usually jumped 7 waves. Here it is a form of luck for the new year. Some people here eat certain foods for the night, and most use white.
