What Is the Meaning of July?

July is named after the Roman dictator Gaius Julius Caesar. The month used to be called Quintilis (“the fifth” in Latin) because it used to be the fifth month in the ancient Roman calendar. Quintilis was renamed Julius in 44 BCE to honor Julius Caesar after his death.

History of July

The old Roman calendar started in March. The fifth month was called mens quintilis. In the year 154 BCE, a rebellion forced the Roman senate to change the beginning of the civil year from March to January 1. With this reform, Quintilis officially became the seventh month but kept its name (for the next 110 years).

After the murder of Julius Caesar on the Ides of March in 44 BCE, Rome was on the brink of civil war: Many within the Roman aristocracy wanted Caesar to be condemned as a tyrant who needed to be purged from history while the Roman citizens admired and adored Caesar. To stabilize the situation, the Roman senate chose to side with the people. They gave Caesar’s birth month Quintilis the new name mens iulius, the month of Julius.
