Months

The month is a unit of time derived from the natural orbital period of the Moon revolving around Earth, historically known as the synodic month lasting roughly 29.53 days. In the modern Gregorian calendar, a month is a formal division of the year ranging from 28 to 31 days, averaging approximately 30.4375 days or 2,629,746 seconds. While not an official SI unit, it remains a primary calendar unit for administrative, financial, and civil scheduling.
