People around the world have many different traditions and rituals to bring good fortune in the new year. When I lived in China, I was always reminded to wear some new clothes on the first day of the new year (of course, that was the Chinese lunar calendar, not the Gregorian calendar). Because I often forgot about this, I usually bought something at the last minute, and it was usually socks.
To learn more about the many ways the new year is welcomed, have a look at this article from Discovery.com and this one from Business Insider. I particularly like the Columbian tradition on the Discovery list: Run around the block with some empty suitcases if you want your new year to be filled with travel! Come the stroke of midnight on January 1st, you might find me tearing down the streets with some Samsonite!
