Pope Gregory XIII in 1582.
The Gregorian calendar is the most widely used calendar system in the world today. It was introduced by Pope Gregory XIII in 1582 as a reform of the Julian calendar.
We currently use the Gregorian calendar, which was introduced by Pope Gregory XIII in 1582 to reform the previous Julian calendar. It is the most widely used calendar system in the world today.
The Mayans, Egyptians, Babylonians, and Chinese all had calendars in the ancient days. The calendar we use to today was first developed by the Romans, under Julius Caesar (the Julian Calendar). That was modified by the Gregorian Calendar (named for Pope Gregory XIII), which we still use today
Pope Gregory mandated the use of the Gregorian calendar on February 24, 1582.
Julius Caesar improved the calendar by revising it and turning the old lunar calendar into a solar calendar. The solar calendar more accurately reflects the seasons. Pope Gregory made a few minor changes to Caesar's basic calendar and the Gregorian calendar is what we use today. However the Julian calendar, the one which Caesar produced, is still used in some instances today, especially religious ones.
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.
Apart from some minor changes introduced by Pope Gregory XIII in 1478,the calendar we still use today is the calendar which was created by Julius Caesar. Caesar reformed the Roman calendar, switching from a lunar to a solar one.
The Sumariens created the calendar that we use today.
