Germanic Weekdays: The Gods in the Week

Folklore & Belief Germanic Weekdays: The Gods in the Week placeholder

The seven-day week came from the Roman Empire to the Germani, with days named after planetary gods. The Germani translated these names into their own pantheon – a classic case of the interpretatio Romana in reverse.

From Mars to Venus

So dies Martis (Mars's day) became the day of Tiwaz/Ziu: English Tuesday, German (southern) "Ziestag" → Dienstag. Mercury's day became Wednesday (Woden's day) = day of Wodan. Jupiter's day became the day of Donar: Thursday/Donnerstag. Venus's day became the day of the goddess Frija: Friday/Freitag.

Why not the same everywhere

In German "Mittwoch" (instead of Wodan's day) and "Samstag/Sonnabend" (instead of Saturn's day) stand out – that is Christian influence. The weekdays are thus a quiet, everyday testimony to how deep the old belief in the gods sits in our language.

"Mercury they worship most … also Hercules and Mars."after Tacitus, Germania 9 (public domain, own translation)
What is documented: The adoption of the Roman planetary week and the equation Mars=Tiwaz, Mercury=Wodan, Jupiter=Donar, Venus=Frija (Tacitus, Germania 9; linguistics of the weekday names).
What is interpretation: The exact equation Wodan=Mercury rests on the Roman view; it does not fit in every respect. "Mittwoch" instead of "Wodan's day" is a later church replacement, not an old Germanic name.

The weekdays show the gods in everyday life. Continue with Frija and the interpretatio Romana.
