How is years measured?

Answer 1

A year - is the time taken for a planet to orbit once around the sun.

Answer 2

Years are typically measured based on the Earth's orbit around the sun, which takes approximately 365.25 days. A calendar year commonly consists of 365 days, with a leap year occurring every four years to account for the extra 0.25 days. This system of measuring years is the most widely used and recognized globally.

Answer 3

On Earth we regard one rotation of our planet around our sun to be one year. Other planets revolve around the sun at different speeds and so have different lengths of years compared to us.
