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.

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.
The Romans had three calendars over the 1,200 years of their history. Only the first one, the Romulean calendar created by Romulus, Rome's first king, had 10 months and this lasted only for about 40 years. The second king of Rome, Numa Pompilius, reformed the calendar and created one with 12 months (the calendar of Numa). The Julian calendar, created by Julius Caesar, also had 12 months. Caesar also switched from a lunar to a solar calendar.

The original Roman calendar was said to be invented by Romulus, the first king of Rome, at around 753 BCE (Before Common Era). The calendar started the year in March (Martius) and consisted of 10 months, with 6 months of 30 days and 4 months of 31 days. The winter season was not assigned to any month, so the calendar year only lasted 304 days with 61 days unaccounted for in the winter. The Romulean calendar was short lived. The second king of Rome, Numa Pompilius, reformed the calendar. The Calendar of Numa had twelve month. It had 6 months of 29 days and 6 months of 31 days. it remained a lunar calender.
