Have you ever thought about Tuesday? How do you rate it in your Days of the Week ranking, how did the seven-day week come to be, or even considered just HOW did the days of the week get their names? Let’s begin our journey with the Babylonians, who marked time with lunar months.
Perhaps the greatest legacy to modern western astronomy was left to us by the Babylonians. We still use many of their original constellations, and the records they kept of astronomical occurrences allow us a glimpse into their view of the heavens.
The Babylonian calendar, a chronological system used in ancient Mesopotamia, was 12 complete cycles of phases of the Moon. Their lunar year was about 354 days. They reconciled it with the solar year, or year of the seasons, by the occasional insertion of an extra month. Their regular activities were curtailed during several days of the month:
- first – the first visible crescent
- seventh – the waxing half-moon
- fourteenth – the full moon
- nineteenth – dedicated to an offended goddess
- twenty-first – the waning half-moon
- twenty-eight – the last visible crescent
- twenty-ninth – the invisible moon
- thirtieth (possibly) – the invisible moon
The Naming of the Days
The Greeks named the days week after the sun, the moon and the five known planets, which were named for the gods Ares, Hermes, Zeus, Aphrodite, and Cronus. They 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 in turn substituted their gods for the Roman gods, Tiu (Twia), Woden, Thor, Freya (Fria), but did not substitute Saturn.
Sunday – Sun’s day
Middle English sone(n)day or sun(nen)day
Old English sunnandæg “day of the sun”
Germanic sunnon-dagaz “day of the sun”
Latin dies solis “day of the sun”

Monday – Moon’s day
Tuesday – Tiw’s day

Woden is the chief Anglo-Saxon/Teutonic god. Woden is the leader of the Wild Hunt. Woden is from wod “violently insane” + –en “headship”. He is identified with the Norse god Odin.
Mercury is the Roman god of commerce, travel, thievery, eloquence and science. He is the messenger of the other gods.
Hermes is the Greek god of commerce, invention, cunning, and theft. He is the messenger and herald of the other gods. He serves as patron of travelers and rogues, and as the conductor of the dead to Hades.

Friday – Freya’s day
Middle English fridai
Old English frigedæg “Freya’s day”

Germanic frije-dagaz “Freya’s (or Frigg’s) day”

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