A Kick-Ass Calendar

The official calendars of the ancient Roman Republic don't show the days of the week. But by the early imperial period, Romans used seven gods' names (Sol, Luna (Moon), Mars, Mercury, Jove (Jupiter), Venus, and Saturn) to delineate the individuals days, although the Roman week itself actually varied in its number of days. It's worth noting that the gods' names are in the Genitive Singular case.

  • dies Solis
  • dies Lunae
  • dies Martis
  • dies Mercurii
  • dies Iovis
  • dies Veneris
  • dies Saturni

Below is a table showing the Latin name for the day of the week, followed by the corresponding modern name in French, Spanish, and Italian. This follows the convention in Italy, etc., of naming Monday first. Please notice that the modern name for Sunday is not connected with the sun god himself, but is related to the word for "Lord," and Saturn's day refers to a Sabbath in the Romance language names for the days of the week, although English uses the Roman deity's name.
