New Year's Day
Résumé
In the Gregorian calendar, New Year's Day is the first day of the year; 1 January. Whilst most solar calendars (like the Gregorian and Julian) begin the year regularly at or near the northern winter solstice, cultures that observe a lunisolar or lunar calendar celebrate their Lunar New Year (such as the Chinese New Year and the Islamic New Year) at less fixed points relative to the solar year.
In pre-Christian Rome under the Julian calendar, the day was dedicated to Janus, god of gateways and beginnings, for whom January is also named. From Roman times until the middle of the 18th century, the new year was celebrated at various stages and in various parts of Christian Europe on 25 December, on 1 March, on 25 March and on the movable feast of Easter.
In the present day, with most countries now using the Gregorian calendar as their civil calendar, 1 January according to that calendar is among the most celebrated public holidays in the world, often observed with fireworks at the stroke of midnight following New Year's Eve as the new year starts in each time zone. Other global New Year's Day traditions include making New Year's resolutions and calling one's friends and family.
The ancient Babylonian calendar was lunisolar, and around the year 2000 BC began observing a spring festival and the new year during the month of Nisan, around the time of the March equinox. The early Roman calendar designated 1 March as the first day of the year. The calendar had just 10 months, beginning with March. That the new year once began with the month of March is still reflected in some of the names of the months. September through to December, the ninth through to the twelfth months of the Gregorian calendar, were originally positioned as the seventh through to the tenth months. (Septem is Latin for "seven"; octo, "eight"; novem, "nine"; and decem, "ten") Roman mythology usually credits their second king Numa with the establishment of the two new months of Ianuarius and Februarius.
