Not every year has 365 days. Typically, a year has 365 days, but every fourth year is a leap year with 366 days. Leap years include an extra day, February 29, to keep the calendar year synchronized with the Earth’s orbit around the sun. This adjustment helps maintain the accuracy of our calendar.

FAQs & Answers

  2. How many days are in a leap year? A leap year has 366 days, which is one day more than a typical 365-day year.
