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).
Obid created the 365 calendar
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.

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.
The Julian Calendar was a calendar reform by Julius Caesar in Rome, introduced in 46 BC. The Julian Calendar divided the year into 365 days and 12 months, with a leap day every 4 years.
1150 was a common year in the Julian calendar. This means that it had 365 days and was not a leap year. Not only was it a common year, but it also started on a Sunday.
