The Month of Augustus

The meaning of August comes from ancient Rome: Augustus is Latin and means “the venerable one” or “the great one.” It was the title given to the first Roman emperor, Gaius Caesar. The Roman senate decided in 8 BCE to name a month in honor of the emperor. They chose the old Roman month of Sextilius and renamed it Augustus.

History of August

In the ancient Roman calendar, August was initially called mens sextilius, the sixth month, because the Roman calendar started in March. Sextilis had 31 days. Around the year 700 BCE, the Roman king Numa Pompilius expanded the calendar from ten to twelve months by introducing January and February. Sextilis was reduced to 29 days.

In 154 BCE, a rebellion forced the Roman senate to change the beginning of the civil year from March to January 1st. With this reform, Sextilis officially became the eighth month.

In the year 46 BCE, Julius Caesar introduced a new calendar system—the Julian calendar. He added ten days to the year and introduced the leap day. In the new Julian calendar, Sextilis was expanded to 31 days.

In the year 8 BCE, the Roman senate then renamed Sextilis to honor the first Roman emperor, Augustus Caesar. Augustus was not the emperor’s name but his title. It means “the great” or “the venerable.” The Roman senate gave this title to the emperor Gaius Caesar Octavius in the year 27 BCE because of his military and political victories that founded the Roman empire.
