Yes. The mechanics of the process that causes the apparent shape of the moon
to change also guarantees that a lunar eclipse can only occur at Full Moon, and
a solar eclipse can only occur at New Moon.
There are two "eclipse opportunities" each year, when the Moon passes the ecliptic (the plane of the Earth's orbit around the Sun) at the new or full moon. And normally, we see either a solar or a lunar eclipse - or both - each time. Occasionally, if the arrangement is off just a bit, we see two partial or penumbral eclipses instead of one total eclipse.
This year, for example, we saw a total solar eclipse at the new moon on July 22, 2009, and a penumbral lunar eclipse two weeks later, on August 6.
Of the two solar eclipses each year that we should expect, about half are partial; one quarter are annular, and a quarter are total. (These are approximations, of course.) Of the two lunar eclipses that we expect each year, about 1/3 are total, and the rest either partial or penumbral.
The NASA Eclipse Web Site lists all eclipses from 2000 BC to 3000 AD; you can look up the exact time and date, and where it was/will be visible.
Yes. So can you. Just look at the moon once or twice a day for 29 days, and make
a sketch of what you see each time you look. There on your paper is your prediction.
The moon will take on all of those same shapes, in the same order, repeatedly. After
the last sketch on the paper, it will go back to the first one on the paper.
The minimum would be 14.5 days; the maximum would be about 195 days.

On earth there are 2 eclipses, Lunar and Solar eclipses
Lunar eclipses were created by our shadow.
There was 2 lunar eclipses in 2008.
Total lunar eclipses occur between 0-3 times per year.
There are between 1 and 4 lunar eclipses per year. Between the years 1901 and 2000, the average was 2.29 of them each year.

yes there are full and partial lunar eclipses
there are at least two lunar eclipses in a year
none to 3 lunar eclipses a year

Solar eclipses occur when the Moon is in the direct path between the Sun and Earth. Lunar eclipses occur when the Earth is in the direct path between the Sun and the Moon.
Total lunar eclipses occur between 0-3 times per year.
There are between 1 and 4 lunar eclipses per year. Between the years 1901 and 2000, the average was 2.29 of them each year.
Lunar eclipses are fairly common sights. There are generally two solar eclipses and two lunar eclipses each year.
it's quite rare, but it's possible to have no lunar eclipses at all in a year, if the geometry between the Earth, Moon and Sun doesn't quite work out. The maximum possible number, again VERY rare, is five. Typically, we have two lunar eclipses per year.
