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.
Historians would use calendars all the time. They are a major part of their work. They are constantly using dates and checking up on them, so calendars are essential to them. They could not work without calendars.

Greece invented democracy and really how did you not know that LOL
