Why do we have leap years?

We have leap years to keep our calendar synchronized with the Earth's orbit around the Sun. The Earth's orbit takes approximately 365.24 days, so adding an extra day every four years helps to account for the extra fraction of a day.

What is the significance of February 29?

February 29 is the extra day that is added to the calendar during a leap year. It occurs every four years, except for years divisible by 100 but not by 400.

Was the year 2000 a leap year?

Yes, the year 2000 was a leap year. Because it was divisible by 400, it followed the exception to the divisible-by-100 rule.
