New Year’s Day , also called simply New Year’s or New Year ,  is observed on January 1 , the first day of the year on the modern Gregorian calendar as well as the Julian calendar. In pre-Christian Rome under the Julian calendar, the day was dedicated to Janus, god of gateways and beginnings, for whom  January also named. As a date in the Gregorian calendar of Christendom, New Year’s Day liturgically marked the Feast of the Naming and Circumcision of Jesus, which is still observed as such in the Anglican Church and Lutheran Church.In present day, with most countries now using the Gregorian calendar as their de facto calendar, New Year’s Day is probably the most celebrated public holiday, often observed with fireworks at the stroke of midnight 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 reason for celebrating day is that it is the first day of the new year, such as beginning of a new year and the prayer of success in work, in learning or in the desire for fellowship with loved ones , with everyone, where all the relatives gather together to celebrate, with their families
