The Roman calendar was divided into months and the name of the months we use today are derived from the names the Romans used. For a short while at the beginning of their history, the Romans had calendar with 10 months. Soon after that, it was reformed and lengthened to 12 months.

The names of the other months came from the older Roman calendar.
