"Swiss" is not a language.
People in Switzerland speak one or more of the following official languages
* German * French * Italian * Romansh Merry Christmas translates as
* German - Frohe Weihnachten
* French - Joyeux Noël
* Italian - Natale allegro
Someone else may add the Romansh version

Feliz Natal Feliz = happy/merry Natal = Christmas
メリークリスマス Merīkurisumasu
Felice navidad
