Lunar Eclipses (the darkening of a full moon by the shadow of the Earth) occur every 6 months, and total lunar eclipses normally come in sets of three, followed by three partial eclipses.
The lunar eclipse of June 26, 2010 is a partial eclipse visible mainly in Australia. There will be total lunar eclipses on December 21 (2010), June 15 (2011), and December 10 (2011).
Solar Eclipses (shadow of the Moon partially or fully blocking the Sun) can occur two to five times a year, but the majority are partial eclipses. Total eclipses occur about once every 18 months, and affect a very limited area. The maximum coverage of the solar disk lasts between 6 and 7.5 minutes.

Solar eclipse:
From 1901 to 2000 (100 years), there are 228 solar eclipses.
Average in the century: 2.28 per year.
Lunar eclipse:
From 1901 to 2000 (100 years), there are 229 lunar eclipses.
Average in the century: 2.29 per year.
One reason we think of lunar eclipses as being much more common is that slightly over half the earth gets to see each lunar eclipse, while solar eclipses are only visible on a relatively small portion of the globe.
The maximum duration of a total solar eclipse is about 7 minutes, but can be as short as a few seconds. Total lunar eclipses are about 1.5 hours.
every ten years
Because for any given point on Earth, lunar eclipses are visible more often than solar eclipses.
There are two main types of eclipses: solar and lunar. Lunar eclipses occur every 6 months. Solar eclipses occur 2-5 times per year. Eclipses can be partial or total. Partial eclipse covers only part of the sun or moon, while total covers the full entity.
On earth there are 2 eclipses, Lunar and Solar eclipses
Solar eclipses can only occur at the new moon, while all lunar eclipses happen at the full moon.
Both solar and lunar eclipses generally occur 2 times a year. Some years you will have fewer, or more. For example, there will be NO solar eclipses at all during 2011! The maximum possible number of solar or lunar eclipses per year is five.

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.
i believe evry 1oo years but I'm not sure

Lunar eclipses occur more frequently than Solar eclipses. About 70 eclipses take place in regular cycles lasting 18 years and 8 or 9 days; usually 41 of these eclipses are solar and 29 are lunar.
Because the moon phase is irregular
Lunar eclipses and solar eclipses happen EQUALLY often; about two of each kind per year. However, solar eclipses are visible only across a small path on the Earth, while lunar eclipses are visible from the entire nighttime hemisphere of the planet.
It can cause lunar eclipses, and solar eclipses.
