A sidereal year (from Latin sidus "asterism, star") is the time taken by the Earth to orbit the Sun once with respect to the fixed stars. Hence it is also the time taken for the Sun to return to the same position with respect to the fixed stars after apparently travelling once around the ecliptic. It equals 365.25636 SI days for the J2000.0 epoch.
A year is the time between two recurrences of an event related to the orbit of the Earth around the Sun. In astronomy, the Julian year is a unit of time, defined as 365.25 days of 86,400 SI seconds each (no leap seconds), or 31,557,600 seconds total.
