yea, thanks, but... i'm sure many of us already know the length of a moon, that it is the amount of time for the phases to cycle

The lunar orbital period is changing versus time, but I odn't remember which way. The moon drags on the earth (causing the tides) and the earth drags on the earth. Eventually their orbits will "lock" or be in synch. Meaning that one lunar orbit around the earth will be the same as a day on the earth. But this would be a combination of the earth changing its day and the moon changing its orbital period. Mercury is close to this "lock" with the Sun (a day on Mercury is almost the same as its year) and the Pluto Charon system is in a similar position.

No, shorter. The moon used to be much closer in, and therefore orbited the Earth much faster. In fact, months are are lengthening a little bit even now.

It's a month long. Approximately.
