Months

The month is a unit of time derived from the Moon's orbital period (approximately 29.53 days per synodic cycle). The Gregorian calendar uses months of 28, 29, 30, or 31 days. In science, the average calendar month is often approximated as 30.44 days (365.25/12). Financial calculations, loan amortisation schedules, and rental agreements are almost universally structured around calendar months.

Years

The year is based on Earth's orbital period around the Sun. The Julian year used in astronomy is exactly 365.25 days (31,557,600 seconds). The Gregorian calendar approximates the tropical year as 365.2425 days through its leap year rule, achieving accuracy to within 26 seconds per year. In geology, time spans are expressed in millions of years (Ma) or billions of years (Ga).
