Where does December come from?

In the 10-month Roman calendar, which started with March, December was the tenth month. When Julius Caesar took control of Rome, he changed the length of some months and added new ones because January was falling in autumn due to the calendar’s inaccuracies. He added Quintilis, later to become July (named after Julius), and Sextilis, which would later become August (named after Augustus Caesar). This is how December went from being the tenth month to the twelfth. Our Gregorian calendar is based on this Julius calendar.
