Julius Caesar created the modern calendar in 46 BC, and it was adopted by Rome in 45 BC.
His Julian Calendar of 365.25 days added winter months that were previously inconsistent, and used leap days to keep the seasons and the calendar in alignment.
The current form is also called the Gregorian Calendarfor Pope Gregory XIII, who in October 1582 introduced the adjustment of the Julian calendar by skipping 10 calendar days, recognizing that the year was actually slightly shorter than 365.25 days. This calendar removes the leap days from end-of-century years (e.g. 1800, 1900) unless the first 2 digits are evenly divisible by 4.
