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.
My teacher said that he invented the calendar. He used his name Julius as July and Octiavan as October and Augustus as August. He sounded pretty clever didn't he! Well I hope my answer helps!!!
The calendar was technically first invented by the Ancient Egyptians.
Julius Caesar is credited with changing the Roman calendar from 355 days to 365 days and for adding leap year days every few years (and for changing the name of Quintilis to July in honor of himself).
Historians do not know who or when mankind invented the first calendar, probably early man when he first carved a notch into a stick or a bone which marked the passing of each full moon. Notched bones used to record moon phases have been found in Africa and Europe dating back to about 20,500 BC. There are many different calendars invented by different cultures to suit their needs. The mayans created a calender, but I believe the calendar we use is based off of the Romans. Some also believe that the Sumerians invented the 12-month 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 calendar we use was invented/made by the Romans in about 46 AD. August is named after Julius Caesar from his death while some the months and days come from Roman gods.
the roman calendar was made by Julius Caesar.
