Christmas Girls

The word Christmas originated as a compound meaning "Christ's Mass". It is derived from the Middle English Christemasse and Old English Cristes mæsse, a phrase first recorded in 1038. "Cristes" is from Greek Χριστός Christos and "mæsse" is from Latin missa (the holy mass).
Celebration
Christmas Day is celebrated as a major festival and public holiday in countries around the world, including many whose populations are mostly non-Christian. In some non-Christian countries, periods of former colonial rule introduced the celebration (e.g. Hong Kong); in others, Christian minorities or foreign cultural influences have led populations to observe the holiday. Countries such as Japan and Korea, where Christmas is popular despite there being only a small number of Christians, have adopted many of the secular aspects of Christmas, such as gift-giving, decorations and Christmas trees. Notable countries in which Christmas is not a formal public holiday include People's Republic of China, (excepting Hong Kong and Macao), Japan, Saudi Arabia, Algeria, Thailand, Nepal, Iran, Turkey and North Korea. Christmas celebrations around the world can vary markedly in form, reflecting differing cultural and national traditions.
