Question

Why is one full day added to the month of February after every four years​

Answer 1

Answer:

leap year exists because one extra day is added to the calendar every four years to make it synchronize with the actual solar year. The Earth's orbit around the sun actually takes around 365.25 days - there is an extra one-fourth day.

Answer 2

Nearly every four years, we add an extra day to the calendar in the form of February 29, also known as Leap Day. Put simply, these additional 24 hours are built into the calendar to ensure that it stays in line with the Earth's movement around the Sun.
