Our current calendar comes for the Julian calendar, the calendar introduced by Julius Caesar. In the 15th century pope Gregory XIII shortened the day of that calendar by about 11 minutes. Apart from that, our calendar is the same as the one introduced by Julius Caesar. Because of this, the name of our current calendar is Gregorian calendar. 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 Julian Calendar was a further reform of the Roman calendar. Two months were renamed after Julius Caesar and Augustus. This is the origin of the names of the months of July and August. The names of the other months came from the older Roman calendar.
