Christmas in Korea is very different from Christmas in North America or Europe. There are some superficial similarities, such as Christmas decorations in shop windows, but look beyond that and the differences become very apparent.
The good news is that Christmas is a national holiday in Korea. That means that if you work in an office, school, or factory that isn’t owned by the local scrooge, then you are likely to have the day off.
Unlike many Asian countries, a large proportion of Koreans are Christian, which explains why the day is a national holiday. It also means that there are special Christmas services in churches around the country.
However, Christmas isn’t one of Korea’s big traditional holidays like Seollal or Chuseok, so there isn’t a mad rush of everybody trying to make it back to his or her hometown for Christmas.
