The exact year that Christmas was made is unknown. However, it is believed to have originated in ancient Rome, where a festival called Saturnalia was celebrated in mid-December. The celebration honored the god of agriculture, Saturn, and included gift-giving, feasting, and decorating with evergreen trees and wreaths. Over time, the festival evolved into the Christian holiday of Christmas, which celebrates the birth of Jesus Christ. The first recorded Christmas celebration in the United States occurred in 1610.
