It happens when the moon is on the opposite side of the Earth from the Sun.
New moons occur every 4 weeks.
There will be a total of 12 Full Moons this year, 2014.
They occur about once a year. Called perigee-syzygy or perigee moons by the astronomical community, they occur when a full or new moon (syzygy) is closest in its orbit to the earth (perigee), when the sun, earth and moon are aligned.
Spring tides occur at full and new moons.

Solar eclipses only happen on New moons when the moon is exactly in orbit between the Sun and the Earth.

On average, one seventh of the full moons occur on a Friday.

The question is a little vague; I'm going to assume you mean full moons. The synodic period (the time between two full moons) averages 29.53 days, which works out to about 12.4 of them per year. In any given calendar year there are either 12 or 13 full moons. 2014 is a "12 full moons" year; 2015 will have 13.
It is because the moon's orbit is tilted with respect to the ecliptic by about five degrees, meaning that at most new or full moons, the moon passes above or below the Earth's shadow, preventing an eclipse.

Full moons occur when the moon is at a point in its orbit where it is opposite the sun relative to the Earth. That happens about once a month. It can be at any time of day or night, depending on where you happen to be on the Earth. However, in most places on Earth, the full moon will not appear above the horizon unless the sun is near or below the horizon. So, the moon can be full any time of day, but you'll only be able to see it at night.
