The mean tropical year is approximately 365 days, 5 hours, 48 minutes, 45 seconds.

One sidereal day is the time it takes for a star (in our case 'the sun') in the sky to come back to the same place in the sky. Because, for all intents and purposes, the sky is "fixed", a sidereal day is when the earth rotates 360°.

A sidereal day is 23 hours 56 minutes and 4.09 seconds long.

So a tropical year is 365.242 mean solar days long and 366.242 Sidereal days long.
