New Year's Day

New Year's Day, celebrated on January 1, is the first day of the calendar year in the Gregorian calendar, and is observed as a public holiday in many countries. The day has its roots in ancient Rome, where it was dedicated to Janus, the god of gateways and beginnings, and was celebrated as a time for family gatherings and celebrations. The Roman calendar initially began the year on March 1, but was later changed to January 1 after the Roman Empire adopted the Julian calendar in 45 BC, which became the predominant calendar in the Western world for over 1,600 years.learn more on wikipedia
