New Year's Day

holiday on January 1st which celebrates the beginning of a new year

New Year's Day is the first day of the year, in the Gregorian calendar, falling exactly one week after Christmas Day of the previous year. In modern times, it is January 1. In most countries, it is a holiday. It is a holy day to many of those who still use the Julian calendar, which includes followers of some of the Eastern Orthodox churches, and is celebrated on January 14 of the Gregorian calendar due to differences between the two calendars. It is usually celebrated with Fireworks, from London at 0:00 to America, at 0:00.
