For Christmas, the Federal Association of Interpreters and Translators offers every year a small but nice service. On it’s webpage, Christmas greetings are translated …
… into more than 80 languages. Alongside such universal languages like English, Spanish or French, the data base also includes Christmas messages in less frequent languages such as Estonian or Javanese.
In English, people would commonly wish each other a: MERRY CHRISTMAS! HAPPY CHRISTMAS! or MERRY X-MAS!
The German language offers at least three ways of expressing good wishes for Christmas: FRÖHLICHE WEIHNACHTEN!, FROHE WEIHNACHTEN! and FROHES FEST!
In Spanish, the Christmas greetings that are used most both in Spain and Latin America are: ¡FELIZ NAVIDAD! and ¡FELICES FIESTAS!
