What is a Year?
The Gregorian year averages 365.25 days (31,557,600 seconds), accounting for the one leap day added every four years (with century corrections). The solar year — one orbit of the Earth around the Sun — takes about 365.2422 days, and the leap-year system keeps the calendar aligned with this astronomical period. Ages, interest rates, and long-range plans are expressed in years. The year 2000 was a leap year; 1900 was not.
What is a Month?
The calendar month averages approximately 30.4375 days (2,629,800 seconds), though individual months range from 28 to 31 days. Months are derived from the lunar cycle (≈ 29.5 days) but are standardized in the Gregorian calendar to produce a fixed 12-month year. Subscription services, utility bills, mortgage payments, and paychecks are all calculated on a monthly basis. February has 28 days in common years and 29 in leap years.
