when was christmas made

Christmas is a holiday that has a long and complex history. The roots of the holiday can be traced back to ancient pagan festivals that celebrated the winter solstice, which is the shortest day of the year and the longest night. These festivals marked the end of the dark winter months and the beginning of the return of the light. Over time, these pagan traditions were absorbed into the Christian calendar and transformed into the Christmas we know today. The celebration of Christmas as a religious holiday began in the 4th century with the conversion of Emperor Constantine.
