Our calendar is the Gregorian Calendar. It is named after Pope Gregory XIII who took 11 minutes of the day of the Julian calendar and made some other minor modifications in 1582. This means that our calendar is a slightly modified version of the Julian Calendar.
All of the English month names are based on the Latin names of the Roman months. The calendar we use is the Gregorian calendar. It derives its name from Pope Gregory XIII who introduced some minor modifications to the Julian calendar in the 16th century. This means that we use a slightly modified version of the calendar introduced by Julius Caesar.
The western world (as well as most of the rest of the world) uses the Gregorian calendar. The calendar is of Christian and Roman pagan origins. The months and days of the week are named after Roman pagan gods and goddesses, and the calendar's epoch date (starting point) is 1 AD, the year Jesus Christ is estimated to have been born. The calendar has 365 days.
Answer The Mayans were the first to develope the calendar. Since then other tribes and groups of people have used it as a way of keeping up with the days, week, month and year. It has changed quite a bit too. Now into the modern calendar we use today. Hope I helped.
Julius Caesar reformed the Roman calendar, and added July (Julias Caesar) and August (Augustus Caesar)
It's not, it's called the Gregorian Calender. Julius Caesar reformed and improved the old Roman calender in the first century B.C. and thus it was called the Julian Calender. His reform was very good but it did not allow for the fact that a year is actually 365.25 days long. It had the year being exactly 365 days. Thus by the Middle Ages the calendar was off by eleven days. Pope Gregory the Great revised it by just cutting out eleven days one year, so the calender would "catch up" with the actual position of the sun and stars in the sky, and adding leap years so that it would not get out of alignment again. Thus we now have the Gregorian Calender.
