When And Where Was The First Christmas Celebrated?

Christmas is celebrated worldwide as the birth of Christ. The name Christmas is derived from the word "Christ's mass". Christmas was celebrated on many different dates before the 200 A.D. The first Christmas is said to be celebrated on many dates before settling on the 25th of December. It is said that the first Christmas was celebrated in the 15th century in Victorian Britain.
The idea of celebrating Christmas on the 25th of December as Jesus Christ's birthday was first made famous by 'Sextus Julius Africanus' somewhere in 221 AD. In the European countries Christmas is economically one of the most important festive seasons.
Although worldwide Christmas is celebrated on the 25th of December, some Catholic and Protestants in Eastern Europe celebrate it on the 7th of January as it is considered to be the official date set by the orthodox churches. This date is determined by the Julian calendar which was introduced in the year 46 BC and was put into practice from 45 BC.
