The months of the Julian calendar are the months we use today. We use the Gregorian calendar, which is a slightly modified version of the Julian calendar. The month July is named after Julius Caesar. August is named after Augustus.
No, there are not thirteen months in a standard calendar year. Most calendars, including the Gregorian calendar widely used today, consist of twelve months. However, some alternative calendars, like the International Fixed Calendar, propose a thirteen-month system, but these are not commonly adopted.
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.
Julius Caesar made up the Julian calendar complete with the 12 months everybody knows way back in the day of the Roman Empire. Many centuries later, Pope Gregory decided to make some small changes to the Julian Calendar and the Gregorian calendar is now the (unofficially) global standard calendar that pretty much everybody today uses.
The months of January and February were added to the Roman calendar.
