FAQs & Answers

  1. What is a leap year? A leap year is a year that has an extra day, February 29, to help synchronize the calendar year with the solar year.
  2. Why is a year not exactly 365 days? The Earth's complete orbit around the Sun takes about 365.25 days, which is why we adjust with leap years.
  3. How often do leap years occur? Leap years occur every four years, but exceptions exist for years divisible by 100 unless they are also divisible by 400.
