The sidereal month is defined as the Moon's orbital period in a non-rotating frame of reference (which on average is equal to its rotation period in the same frame). It is about 27.32166 days (27 days, 7 hours, 43 minutes, 11.6 seconds). The exact duration of the orbital period cannot be easily determined, because the 'non-rotating frame of reference' cannot be observed directly. However, it is approximately equal to the time it takes the Moon to pass twice a "fixed" star (different stars give different results because all have proper motions and are not really fixed in position).
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.
We default to using the Gregorian year on this site, but you can select a specific type of year by entering the full name like "Julian year".
