Answer 1

Explanation:

In every year 1 quarter day will increase. After 4 years the 4 quarters makes a day so that leap year comes.

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. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
