Months have a certain number of days because calendars were designed to align with the Earth's orbit around the sun. Most months have 30 or 31 days to roughly match the lunar cycle, but February has 28 or 29 days to adjust for the solar year's slight inaccuracy (365.25 days). This structure helps in organizing agricultural, financial, and social activities throughout the year.
