The average is 14.75 days from the Earth for "day" and the same for "night".

The moon doesnt rotate like the earth, a lunar day is the period of time it takes for the Moon to complete one full rotation on its axis with respect to the Sun. Equivalently, it is the time it takes the Moon to make one complete orbit around the Earth and come back to the same phase. It is marked from a New Moon to the next New Moon.
With respect to the stars, the Moon takes 27 d 7 h 43.2 min to go around in its orbit, but since the Earth-Moon system has advanced around the Sun in the mean time, the Moon must keep going a while longer to get back to the same phase. On average, this synodic period is 29 days, 12 hours, 44 minutes and 3 seconds long.

A 'day' is defined as the time it takes for a body in space (a planet or moon etc) to rotate once on its axis. It takes about 28.5 'Earth days' (684) hours to do this, so you could say a Moon day is 684 hours long.
However, if by 'day and night' you mean 'light and dark', you can see by watching the moon that any one particular spot is light for half a month and dark for the other half. So you could equally say that a Moon day is 342 hours long (about two weeks), as is a Moon night.

Since bladecrimson did not cite the article from which he/she got his answer, I am providing it below.
The Moon always has the same face facing the Earth due to tidal locking. Unlike what religious people want you to believe, this is no miracle.
