The 365 day calendar was technically first invented by the ancient Egyptians. They had a 360 day calendar that had 12 months with 3 seasons (Akhet - June 15 to October 15, Proyet - October 15 to February 15 and Shomu - Februray 15 to June 15). The calendar corresponded with the flooding of the Nile River which occurred around June 20th, not long after the star Sirius (from the constellation Canis Major) reappeared on the eastern horizon. Five extra days were added at the beginning of each year and during these days, the birthdays of the gods were celebrated. Thus, bringing their calendar to 365 days. However, they did not compensate for the leap year as we do today so the calendar and seasons drifted out of line. This eventually lead to a 5 month discrepancy at the end of the Old Kingdom.

Several early civilisations adopted the 365 day calendar. Notably the Ancient Egyptians. Certainly before 3000 BC
The Mayan civilization!
Rome, I believe.
Obid created the 365 calendar
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).
The Egyptian
It is not know precisely who or where the first 365 day calendar was invented or used. Many cultures on many continents used and invented it independently.
No. The Aztecs are credited with making the 365-day calendar.
so they could keep track of the days and special event and holidays they had
Egypt were the first ones to use the 365-day calendar
It was a 365-day calendar similar to our present-day calendar.
The ancient Egyptians had a 360 day calendar, but i do believe they were the founders of the 365 calendar. Hope it help :)
One common example would be the Mayans. They invented the 365 day calendar.
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.
a superwhore day to day calendar
The ancient Olmecs invented both things, although so did others in other parts of the world independently.
