Well, other celenders had been invented before the Romans but the one we use today is the one they developed and which Julius Caesar perfected. Only one major change has been introduced since Roman times, the use of leap years.
Of course they did! The calender we use is actually the same one the Romans invented and had. Julius Caesar reformed it. So you know, this is what all the names of the months mean:
January: Janus--god of doors and beginnings and endings
February: Latin word februare which means "to purify"
March: Mars--the God of War
April: Latin word aperire which means "to open"
May: Maia--goddess of spring
June: Juno--goddess of marriage; protector of women; wife to Jupiter
July: Julius--Julius Caesar was honoured by having his name in it
August: Augustus--the grandnephew of Caesar (later to be called Augustus) and the first emperor of Rome.
September: Latin septem "seven"
October: Latin octo "eight"
November: Latin novem "nine"
December: Latin decem "ten
Yes, he "invented" the Julian calendar. The Roman calendar had been a lunar calendar up until Caesar's time. The priests who were responsible for maintaining it had let it slip horribly out of date. Spring festivals were celebrated in winter and vise versa. Caesar, along with Egyptian astronomers, devised a solar calendar, which was more accurate. There is very little difference between the Julian calendar and the Gregorian calendar which we use today and some Christian religious festivals are determined by the Julian calendar.
