Just so, who invented the calendar of 365 days?
The Egyptians were probably the first to adopt a mainly solar calendar. This so-called 'heliacal rising' always preceded the flood by a few days. Based on this knowledge, they devised a 365-day calendar that seems to have begun in 4236 B.C.E., the earliest recorded year in history.
Subsequently, question is, when did Year 1 start? In some ways, yes. When Julius Caesar introduced his calendar in 45 B.C.E., he made 1 January the start of the year, and it was always the date on which the Solar Number and the Golden Number were incremented.
Thereof, who made the first calendar?
In 1582, when Pope Gregory XIII introduced his Gregorian calendar, Europe adhered to the Julian calendar, first implemented by Julius Caesar in 46 B.C. Since the Roman emperor's system miscalculated the length of the solar year by 11 minutes, the calendar had since fallen out of sync with the seasons.
