Kathen is one of the most important festivals in Cambodia . It is not a national ceremony, but it is religious festival because we celebrate it in the pagoda. Usually we celebrate Kathen from the middle of October to the middle of November. It lasts a month. In fact, every pagoda must hold Kathen once a year. We can also celebrate Kathen at home to collect the presents for the monks by Inviting the monks to pray in our houses and some times we invite one or two of the monks to preach for the people. In the next moming,we take the presents to the pagoda with guests. In the pagoda, for the night on the first day,we go to the pagoda to play and listen to the monk's sermon and after that we sometimes enjoy watching a play or a film in the next moming, the people gather in the pagoda again and some people come from city or town to join this festival. It is really exciting during the Kathen.
