It seems that everyone has something unique that they add to Christmas or other seasonal holiday. These often have a combination between cultural, religious, or ancestral importance to them.
Some have simple traditions such as everyone opens one gift on Christmas eve, or everyone attends midnight mass. In Ireland for example, Christmas lasts from Christmas Eve to the feast of the Epiphany on January 6th. Overall it is more of a religious meaning than social. On the other hand, Bulgarians make Christmas wishes around the fire and eat blood sausage.
What are your unique Christmas Traditions are they rooted in religious symbolism, or is it something that your ancestors passed down from generation to generation. Or it could be something regional such as everyone in the city goes to see the lighting of the community tree. Tell us about your Christmas.
