The custom of exchanging gifts on Christmas has roots in numerous cultural and religious customs.
The biblical account of the Magi, often referred to as the Three Wise Men, who presented the infant Jesus with gifts of gold, frankincense, and myrrh is one of the traditions' main sources. On Epiphany, which is observed on January 6th in some Christian traditions, this story is remembered, and on this day, gifts are frequently given and received.
The Roman celebration of Saturnalia, which was observed from December 17 to December 23, is another root of the custom. People traded gifts and added greenery to their homes to celebrate the occasion during this holiday.
However, it is generally agreed that the custom of exchanging gifts on Christmas dates back to the Victorian era in the 19th century. During this time, Christmas evolved into a festival that was more focused on families and commerce, with gift-giving taking center stage.
It's also important to note that various countries and religions have unique ways of celebrating the holiday season, and giving gifts is a typical custom at this time of year.
