Gregorian Calendar

The Gregorian calendar is a solar calendar with 12 months of 28–31 days each. A regular Gregorian year consists of 365 days, but in certain years a leap year, a leap year has 366 days, with the 29th of February as an intercalary day. The Gregorian calendar is a modification of the Julian calendar first used by the Romans. The Julian calendar, proposed by Julius Caesar in 46 BC, had a regular year of 365 days divided into 12 months, with a leap day every fourth year. Leap days were added to the month of February. In 1582, Pope Gregory XIII introduced a refinement to the Julian calendar, reducing the number of leap years and correcting for a small error in the computation of the length of the solar year. The Gregorian calendar has since been adopted by most countries for civil purposes. The Gregorian calendar is a solar calendar.
