What is Monday named after?

Mondays are the start of the work week for many people around the world. But have you ever wondered where the name “Monday” comes from and what it means? As it turns out, Monday has an interesting history and origin story.

The Origins of the Names of the Days of the Week

The names of the days of the week in English are based on the names used by the Romans in ancient times. The Romans named the days of the week after the seven celestial bodies known to them – the Sun, the Moon, and the five planets Mercury, Venus, Mars, Jupiter and Saturn. Here is how each day got its name:

  • Sunday – Named after the Sun
  • Monday – Named after the Moon
  • Tuesday – Named after Mars (Martis in Latin)
  • Wednesday – Named after Mercury (Mercurii in Latin)
  • Thursday – Named after Jupiter (Jovis in Latin)
  • Friday – Named after Venus (Veneris in Latin)
  • Saturday – Named after Saturn

So Monday was named after the Moon, which is why in Spanish it is called “Lunes” coming from the word “Luna” meaning Moon. In Latin, the word for Moon was “Luna” and the word for day was “Dies”. So Monday was called “Dies Lunae” meaning “Day of the Moon”.
