How long does it take the earth to revolve around the sun in solar year?

Answer 1

Earth takes 365.256 days to complete one orbit of the sun. To make things easier, we assume 365 days, with an extra day every four years (a leap year) which comes from the fraction left over.

Answer 2

It takes approximately 365.25 days for the Earth to revolve around the Sun, which is equivalent to one solar year. This is why we have a leap year every four years to account for the extra quarter day, making the average year 365.25 days long.
