One fun fact about Friday that people may not know is that the word "Friday" has its roots in Norse mythology. In Old English, Friday was named after the Norse goddess Frigg, who was associated with love and fertility and was considered the wife of Odin, the chief god. The day was originally called "Frīgedæg" in Old English, meaning "Day of Frigg."

In Romance languages, Friday is named after the Latin phrase "dies Veneris," which means "day of Venus." Venus was the Roman goddess of love, beauty, and fertility. So, whether you look at it from a Norse or a Roman perspective, Friday has interesting mythological connections.
