FAQs & Answers
- What exactly is a leap year? A leap year is a year that contains an extra day, February 29, making the year 366 days long. It usually occurs every four years to keep the calendar year synchronized with the astronomical year.
- Why does February sometimes have 29 days instead of 28? February has 29 days during leap years to compensate for the fact that a solar year is approximately 365.25 days, not exactly 365. Adding a day every four years keeps the calendar aligned with Earth's orbit.
- Are all years divisible by 4 leap years? Not all years divisible by 4 are leap years. If a year is divisible by 100, it is not a leap year unless it is also divisible by 400. For example, 2000 was a leap year, but 1900 was not.
