Basically, yes, they did, although Julius Caesar gets the historical credit for it. Caesar used the Egyptian astronomers to help calculate and reform the out of date calendar that the Romans were using.
The flooding of the nile
The ancient Egyptians developed the 365-day calendar around 4236 BCE. This calendar was based on their observations of the solar year and was divided into 12 months of 30 days each, with an additional five days added at the end of the year. This innovation helped them align their agricultural activities with the annual flooding of the Nile River.

The Aztec calendar recognised 365 days
The earliest recorded in ancient history calendar was the "Egyptian calendar" around 4236 B.C.E. They devised a 365-day calendar basing on the moon's cycles or what is called the solar calendar.
The ancient Egyptians had a 360 day calendar, but i do believe they were the founders of the 365 calendar. Hope it help :)
Several early civilisations adopted the 365 day calendar. Notably the Ancient Egyptians. Certainly before 3000 BC

ancient egyptians :D There has always been 365 1/4 days in a year. Thats a physical fact, that no one can alter. How it is divided up into months, is arbitary. Our modern calendar was formulated by pope Gregory and is known as the Gregorian calendar.
