Kinda like a christian who says that Thor's day is the 5th day of the week.
Counting from Sunday then I guess... I count Monday as the first day of the week. Anyway...
...it does not stop with Thor:
Tuesday -
Tyr's Day
Wednesday -
Woden's (Odins) Day
Thursday - Thor's Day
Friday -
Freyja's Day
And the meaning is also preserved in German, Dutch, Afrikaans, Danish, Norwegian, Swedish, Icelandic (besides some exceptions in German and Icelandic; for instance Wednesday is called "midweek" in German and Icelandic) and might very well be in other Germanic languages like Faroese and Frisian etc. Finish, which is not a Germanic language, has also these references to pagan gods in the weekdays.
Monday and Sunday are celebration to the Moon and the Sun which always been very important in almost any ancient religious systems... Saturday is in English the ancient roman god
Saturn but in Scandinavian languages Saturday refers to the day of the week when you was washing (I find this deviation interesting as most Germanic people, with their pagan beliefs, never accepted the Roman occupation and their culture and in particular as the Gothic people of Scandinavia was never under any ancient Roman rule ...)
Then of course we have the reference to ancient Roman gods and culture in the moth names... and not to mention a lot of pagan symbols during x-mass with North Germanic people.
Jesus was for well over a thousand years just another god, seen by some as more powerful, to sacrifice to in order to gain victory in war and other conflicts. Christianity, I would say in my limited knowledge of this, was formed, shaped and merged into an already present deep rooted ancient pagan religions in European Roma occupied countries - just in the same way Christianity got it first grip of the Romans.
