Why Some Years Have 366 Days
Earth takes approximately 365.2422 days to orbit the Sun. To keep the calendar aligned with Earth's orbit, we add a leap day (February 29) roughly every 4 years. Without leap years, seasons would gradually shift out of sync with calendar months.
How to Know If a Year Is a Leap Year
The Gregorian calendar uses these rules: A year is a leap year if it is divisible by 4, except for century years (divisible by 100), which must also be divisible by 400. So 2024 is a leap year, 1900 was not, and 2000 was a leap year.
