A millennium is a period of time equal to one thousand years. There are two main viewpoints about naming millennia and there was a popular debate leading up to the celebrations of the year 2000 as to whether 2000 was the beginning of a new millennium. Historically, there has been debate around the turn of the millennium, centuries and decades before.

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).
