Seven Gods of the Weekdays

The Seven-Day Week and the Meanings of the Names of the Days

The Babylonians marked time with lunar months. They proscribed some activities during several days of the month, particularly the

  • first — the first visible crecent, which shows at sunset
  • seventh — the waxing half moon, which rises approximately at noon
  • fourteenth — the full moon, which rises as the sun sets
  • nineteenth — dedicated to an offended goddess, Bau or Gula, invoked to curse those who trample upon the rights of rulers or those who do wrong with poisonous potions. special “evil day”, the “day of anger”, because it was roughly the 49th day of the (preceding) month, completing a “week of weeks”
  • twenty-first — the waning half moon, whis rises approximately at midnight
  • twenty-eigth — the last visible crescent, which shows at sunrise
  • twenty-nineth — the invisible moon, and
  • thirtieth (possibly) — the invisible moon. These are “dark” moons because the moon rises at the same time as the sun, and therefore, is too pale to be seen, unless there is an eclipse.

The major periods are seven days, 1/4 month, long. This seven-day period was later regularized and disassociated from the lunar month to become our seven-day week.

The Naming of the Days

The Greeks named the days week after the sun, the moon and the five known planets, which were in turn named after the gods Ares, Hermes, Zeus, Aphrodite, and Cronus. The Greeks called the days of the week the Theon hemerai “days of the Gods”. The Romans substituted their equivalent gods for the Greek gods, Mars, Mercury, Jove (Jupiter), Venus, and Saturn. (The two pantheons are very similar.) The Germanic peoples generally substituted roughly similar gods for the Roman gods, Tiu (Twia), Woden, Thor, Freya (Fria), but did not substitute Saturn.

Sunday — Sun’s day

Sunna, Norse goddess of the sun

Sunna, Norse goddess of the sun, chased by wolves

Sunna was the Norse goddess of the sun in her chariot.

Ancient Greek hemera selenes “day of the moon” Not much is said of Mani, other than his being the Man in the Moon. Other cultures see other images, such as rabbits.

It’s unusual for the Sun to be seen as female and the Moon as male, which may show the relatively strong position that women had in the Norse cultures. Freya was the leader of the Valkyries, for example, and she got her pick of fallen warriors first. Other sun goddesses are Brigid, Aine, Olwen and Saule. Amaeterasu is venerated today as the sun goddess in Japan.

Wednesday — Woden’s day

In some interpretations, Wodin took over the pantheon and assumed Tyr’s place. Woden is associated with two crows, Hunin and Munin, Thought and Memory.

Germanic frije-dagaz “Freya’s (or Frigg’s) day”
Latin dies Veneris “Venus’s day”
Ancient Greek hemera Aphrodites “day of Aphrodite”

Freo is identical with freo, meaning free. It is from the Germanic frijaz meaning “beloved, belonging to the loved ones, not in bondage, free”.

Freya (Fria) is the Teutonic goddess of love, beauty, and fecundity (prolific procreation). She is identified with the Norse god Freya. She is leader of the Valkyries and one of the Vanir. She is confused in Germany with Frigg. her name means “Lady”. She had a magical cloak of falcon feathers that allowed her to fly and she sometimes rode her wild boar  Hildisvíni

Cronus was the ancient Greek god of time. He is often represented with a scythe and an hour glass, and is show here with a chariot pulled by flying snakes.

I wonder if this day name comes about due to the Roman invasion of Britain by Julius Caesar, since it’s the only non-Germanic day name? We’ll probably never know.

  1. Very interesting! I knew about the rest, but Freya’s day is something new. Thanks for sharing!

  2. Interesting information … thanks for a little bit of education this morning 🙂

    Nice breakdown. I’m not sure the “dangerously insane” etymology for Odin/Wotan/Woden is entirely accurate — I thought the derivation was more closely related to the idea of religious ecstasy and fury of storm winds … more Zeus than the Joker. 😉

    Great details on all these entries — good job.

    • Odin/Wotan learned the female-only shamanism of seidr, and he gave up an eye in order to gain the runes, at least according to some folks. He wasn’t a trickster in the sense of Loki. I took the etymology to mean “leader of the wild hunt” but he was also the leader of the AEsir, who overtook and subsumed the elder Vanir, of whom Freya was a member. It’s been fun putting these posts together.

  5. Great information and so interesting… I had never thought about where the names came from- though I did have a discussion with my son about what we thought the days of the week should be named:)

    • It’s pretty clear that the Indo-Europeans spread along the path from Inda to Greek and Rome and then north, as the belief systems line up so carefully. But the stories don’t line up. Only the Norse have the idea of Ragnarok, the end of the gods. It’s not at all similar to the Second Coming. Fascinating stuff that leaves traces in our daily lives.

    In the following versions of these myths, Hemera is synonymous with the goddess Eos.
