What is New Year Day Holiday ?

New Year's Day is observed on January 1st, the first day of the year on the modern Gregorian calendar as well as the Julian calendar used in the Roman Empire.Traditionally, as a date in the Gregorian Calendar of Christendom, New Year's Day liturgically marked the Feast of the Circumcision of Christ, and is still observed as such in the Anglican Church and Lutheran Church. However, with most countries now using the Gregorian calendar as their main calendar, New Year's Day is probably the world's most celebrated public holiday, often observed with fireworks at the stroke of midnight as the new year starts in each time zone
