Question

what is a leap year ?​

Answer 1

Answer:

one year in every four, in which February has 29 days instead of 28.

Answer 2

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. ... But approximately every four years, February has 29 days instead of 28. So, there are 366 days in the year. This is called a leap year.

Explanation:

why do we have a leap year?

2020 is a leap year, a 366-day-long year. Every four years, we add an extra day, February 29, to our calendars. These extra days – called leap days – help synchronize our human-created calendars with Earth's orbit around the sun and the actual passing of the seasons.
