In Britain，Boxing Day is usually celebrated on December 26th（61） 　　This means it's not a working day in the whole of Britain．When Boxing Day falls on a Saturday or Sunday，the following Monday is the public holiday．

（62） 　　One of the thoughts is that during the Middle Ages，when great sailing ships were setting off to discover new land，a Christmas Box was placed by a priest（神父） on each ship．Those sailors who wanted a safe return would drop money into the box．（63） 　　

One more thought is about the"Alms Box"placed in every church on Christmas Day．Worshippers （做礼拜的人）put gifts for the poor into it．These boxes were always opened the day after Christmas．（64） 　　Today，many businesses，organizations and families try to keep the traditional spirit of Boxing Day alive by giving away money to Food Banks，providing gifts for the poor，or helping families in need． （65）
