Christmas (December 25) was first officially recorded in the Gregorian calendar in the year 336 CE. That year, the Church of Rome designated December 25 as the day to commemorate the birth of Jesus. Prior to this, various festivals were celebrated throughout the Roman Empire, but the official recognition of December 25 as Christmas was established by the Western Church in 336 CE. This decision came at a time when the Roman Empire was experiencing significant religious and social changes, with Christianity gradually gaining official and widespread status. The choice of December 25 coincided with traditional Roman winter festivals such as Saturnalia, and over time, this date became one of the most important Christian observances. In the following years, Christmas developed a variety of customs and symbols and spread throughout the Christian world. Today, it is observed in many countries as a public holiday, marked by religious ceremonies, family gatherings, and the exchange of gifts. December 25, 336 CE was added to the Gregorian calendar as the first official Christmas to unify Christian practices and establish a fixed date for celebrating the birth of Jesus.
