Christmas Day is an annual holiday celebrated on December 25 that commemorates the birth of Jesus of Nazareth. In America, Christmas season traditionally begins after Thanksgiving holiday on the 4th Thursday November. And the next Saturday, Santa Claus parades in New York to tell everyone Christmas shopping season is coming. That's really so funny, and different from Japan. Also, Christmas in America is a day for spending at home with family. Everyone decorates a Christmas tree with shining tinsel and ornament at home, and cooks gorgeous Christmas dinner and eats them with family. That's really a feeling of hospitality.
