I'm not sure exactly what this means, but the answer may be:
The Umbra and the Penumbra
== == An eclipse occurs because one heavenly body moves between another body and the Sun. For the Moon to be eclipsed, the Earth must be between the Moon and the Sun. For the Earth to be eclipsed, the Moon must be between the Earth and the Sun. Because the Moon orbits the Earth every four weeks, it will be on the opposite side of its orbit in two weeks. Therefore, a total eclipse of the Sun can be followed in two weeks by a total eclipse of the Moon.
There are generally two solar eclipses and two lunar eclipses each year. Of the lunar eclipses, about 40% are "total"; the remainder are partial or penumbral. A lunar eclipse is visible from one-half of the Earth's surface. So on average, and weather permitting, you will see a total lunar eclipse about every third year.
The least common type of lunar eclipse in North America is a hybrid eclipse, which is a combination of a total and annular eclipse. This type of eclipse occurs when the moon transitions between being partially obscured by the Earth's umbra and then by its antumbra. Hybrid eclipses are rare and may not always be visible from North America.
If you're referring to complete lunar eclipses (a lunar eclipse when the moon is full) then unlikely....but any other lunar eclipse (any other moon phase) usually happens atleast twice a year.
There is the total Eclipse, where the moon totally covers the sun. Then there is a partial eclipse, where the moon passes across the sun, but not right through the middle - so we just see a 'bite' out of the sun at most. Then there is an annular eclipse, where the moon goes directly in front of the sun, but the distance is such that it is not able to cover the sun completely - the moon appears too small and the sun shines around it to make a ring. There is also a hybrid, which is where at some points on earth a total eclipse may be seen, but in other locations an annular eclipse may be seen. These are all four types of solar eclipse, there is also the lunar eclipse where the earth obscures light to the moon.
IN a lunar eclipse, the Earth is in the middle, casting a shadow onto the Moon.
There are two types of eclipse : 1)Lunar eclipse 2)Solar eclipse Lunar eclipse is a situation, when the earth comes between sun and moon.

There are two types of eclipse : Lunar eclipse (moon), Solar eclipse (sun) . Lunar eclipse is a situation, when the earth comes between sun and moon.
you question is when do you see lunar eclipes?, you see lunar eclipse at least two times a year , each year. you question is when do you see lunar eclipes?, you see lunar eclipse at least two times a year , each year. you question is when do you see lunar eclipes?, you see lunar eclipse at least two times a year , each year.
eclipse is of two kinds- solar eclipse and lunar eclipse
Solar and lunar
There are, on average, two solar eclipses and two lunar eclipses each year. In 1999, there was an annular solar eclipse on February 16, and a total solar eclipse on August 11. For lunar eclipses, there was a penumbral lunar eclipse on January 21 and a partial lunar eclipse on July 16. You can look up all eclipses from 2000 BC to 3000 AD on the NASA Eclipse web page.

Every nation on the world sees a lunar eclipse on an average of every two or three years. The next total lunar eclipse will be on December 21, 2010 and will be visible from any place in North America. (Weather permitting, of course!)
