True. A leap year occurs every 4 years to help synchronize the calendar year with the solar year, or the length of time it takes the Earth to complete its orbit around the Sun. This means adding an extra day, February 29, to the calendar every fourth year. Years divisible by 100 are not leap years unless they can also be divided by 400. Therefore, the year 2000 was a leap year, but 1900 was not.
FAQs & Answers
- Why do we have a leap year every 4 years? A leap year occurs every 4 years to add an extra day, February 29, helping synchronize the calendar year with the Earth's orbit around the Sun.
- Are all years divisible by 4 leap years? Not all years divisible by 4 are leap years. Years divisible by 100 are not leap years unless they are also divisible by 400, like the year 2000.
- Why was the year 1900 not a leap year but 2000 was? The year 1900 was not a leap year because it is divisible by 100 but not by 400, while 2000 is divisible by both 100 and 400, making it a leap year.
