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).
There are 12 Julian months in a Julian year, and the Julian year is 365.25 days long, so the Julian month is 30.4375 days in length.
We default to using the Gregorian month on this site, but you can select any type of month by entering the full name like "Julian month".
