- January
- February
- March
- April
- May
- June
- July
- August

Each month has a varying number of days, with February being the shortest month with 28 or 29 days in a leap year, and the rest having 30 or 31 days. The names of the months are derived from various sources, including Roman gods, Roman numbers, and Latin words.

The Gregorian calendar, named after Pope Gregory XIII, who introduced it in October 1582, is a refinement of the Julian calendar. It was designed to better approximate the tropical year, the time it takes Earth to complete a full orbit around the Sun, which is about 365.2425 days.
The months in the Gregorian calendar have a mix of 30 and 31 days, except for February, which has 28 days in common years and 29 days in leap years. A leap year occurs every four years, except for years that are divisible by 100 but not by 400. For example, the year 2000 was a leap year, but the year 1900 was not.
