Why is it called Boxing Day?

We know it as boxing day because rich people used to box up a gift to give it to poor. This day was usually a day off for servants, needy people, poor and the day when they received a special Christmas box from their masters or from one special and rich person. The servants would also go home on this day to give Christmas boxes to their families and enjoy this precious time of his life with them.
