The very FIRST one? Probably Ugghhh the Caveman, but it probably wasn't very accurate.
The Egyptians and Babylonians had fairly accurate solar calendars; that is, calendars that corresponded more-or-less to the annual cycles of the seasons.
The Romans came up with a fairly good one, which was used in Europe for almost 1600 years; it was attributed to the emperor Julius Caesar, and is called the "Julian Calendar". It measured the year as 365.25 days, and included one leap year and three regular years.
But by the 1500;s, the Julian Calendar had slipped out of synchronization with the solar year by almost 11 days, and the date of Easter was coming too early. So a commission ordered by Pope Gregory devised the current "Gregorian" calendar that we still use today. Over the course of about 100 years, more and more European nations adopted this calendar, which finally included Britain in the mid-1700s.
There are other calendars in use; most common are the Hebrew calendar, which is luni-solar, and the Islamic calendar which is strictly lunar.

Solar Calendar:?
A solar calendar is a type of calendar that is based on the position of the Earth in relation to the sun. This means that the calendar is organized around the length of the solar year, which is the time it takes for the Earth to complete one orbit around the sun. Solar calendars are used to keep track of the seasons and to organize events and appointments throughout the year. Some examples of solar calendars include the Gregorian Calendar, the Julian Calendar, and the Hindu Calendar. The solar calendar is the most widely used calendar system in the world and is the standard for civil and commercial purposes.

Does the luni solar calendar directly relate with the moon and the sun?
A purely solar calendar, such as the Gregorian calendar that is commonly used, has no connection to the cycles of the Moon, and is tied strictly to the solar year. Months are pretty much arbitrary. In a lunar calendar, the month always begins at the new moon, and dates always occur on the same phase of the Moon. A purely lunar calendar (such as the Islamic calendar) does not synchronize with the solar year at all. A luni-solar calendar such as the Hebrew calendar is primarily tied to the Moon, but also adds "leap months" periodically to maintain a rough match with the solar year.
