Yes, Christmas is celebrated in Korea, but it is not a public holiday and is not widely observed. It is a relatively new holiday in the country and is mainly celebrated by Christians. Many people still celebrate the Lunar New Year, which is considered the most important holiday in Korea. However, Christmas has become more popular in recent years, with people exchanging gifts and enjoying festive meals. In some parts of Korea, there are also Christmas markets where people can shop for holiday decorations and gifts.
