Mánudagr

Mánudagr is the Old Norse word for Monday. The name derives from Old English "Mōnandæg", meaning "the day of the moon". In Norse mythology, the moon was often associated with the god Máni, a personification of the moon who travels across the sky. Therefore, Mánudagr literally translates to "Máni's day" or "the Moon's day". This naming convention for Monday is shared across many Germanic languages, reflecting a common linguistic and mythological heritage. For example, in German it is Montag, and in Dutch it is Maandag. The concept of naming days after celestial bodies or deities is ancient, and Monday's connection to the moon is a prominent example of this practice in the development of the European calendar and naming conventions.
