Monday is an unusual yet intriguing given name, derived from the Latin dies Lunae and the Old French moandaie, both of which mean "day of the moon." This name has been used as a first name since the 19th century but gained more popularity in recent decades, likely influenced by its use as a character's name in various works of fiction. It is often associated with the day of the week that shares its name, Monday, which is the first day of the traditional workweek. However, it remains a unique choice, offering parents an alternative to more common names like Luna or Mona while still having a celestial and somewhat mystical connection.
The name Monday appears to have been popular among parents for their newborns across several decades, with a noticeable spike in the late 1960s and early 1970s. However, it seems that this popularity has waned over time, as there were no recorded births named Monday between 1975 and 1992, and only one each in 1992 and 2020. Overall, the name Monday has been given to a total of 35 newborns across these years.
