Why are the days of the week named after Norse gods?
While we might not actively worship them today, the ancient Norse and Anglo-Saxon gods live on every time we check a calendar. Most English days of the week are named directly after these mythological figures.
The Roman Influence
The 7-day week was originally popularized by the Roman Empire, which named the days after their classical planets and associated Roman gods:
- Sol (Sun)
- Luna (Moon)
- Mars (God of War)
- Mercury (Messenger God)
- Jupiter (King of the Gods)
- Venus (Goddess of Love)
- Saturn (God of Agriculture)
The Germanic Adaptation
When the Germanic tribes (including the Anglo-Saxons) adopted the 7-day week, they engaged in interpretatio germanica—matching Roman gods with their own equivalent Norse and Germanic deities based on shared characteristics.
Here is how the Norse gods took over the calendar:
- Tuesday (Tiw's Day): Tiw (or Tyr) was the Norse god of single combat and law, making him the equivalent of the Roman war god Mars.
- Wednesday (Woden's Day): Woden (Odin) was the chief Norse god, associated with wisdom, poetry, and magic, mapped to the swift-moving messenger god Mercury.
- Thursday (Thor's Day): Thor, the thunder god associated with strength and protection, was matched with Jupiter (or Jove), the Roman god of the sky and thunder.
- Friday (Freya's or Frigg's Day): Frigg (or Freyja), the goddess of love, beauty, and fertility, was the natural equivalent to the Roman goddess Venus.
The Exceptions
Not all days follow this Norse pattern:
- Saturday, Sunday, and Monday retained their celestial Roman origins in English, honoring Saturn, the Sun, and the Moon respectively.
Through language and time, the ancient pantheon of the North remains permanently embedded in our daily modern routines.
