Question

Explain in your own words why we have a leap year on every fourth year.​

Answer 1

Answer:

It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.

Answer 2

Answer:

A common year has 365 days and a leap year 366 days, with the extra--or intercalary--day designated as February 29.

Explanation:

A leap year occurs every four years to help synchronize the calendar year with the solar year, or the length of time it takes to complete the Earth's orbit around the sun, which is about 365 days and a quarter of a day.

Hope it helps you.
