About two per year, since the Moon formed. So, around 4000 solar eclipses (and 4000 lunar eclipses) since the year 1. You can check the list of all eclipses since the year 2000 BC on the NASA Eclipse Web Page at the link below.
Globally, solar eclipses are slightly more frequent. But a lunar eclipse can be seen from any place where the Moon is above the horizon, whereas a solar eclipse can only be seen from a narrow strip of land. So, for any particular fixed observer, solar eclipses - and especially total solar eclipses - are quite rare. During the 100 years of the 20th Century, there were 228 solar eclipses and 229 lunar ones. So over the long term, you can figure on equal numbers, at the rate of around 7 of each every 3 years.
An eclipse of the moon happens when the shadow of the earth falls across the moon. This happens on a recurring basis and thus your question is meaningless - as eclipses of the moon have happened in the far past and will continue to happen into the fare future - counting them is impossible!
Eclipses of the moon are more frequent than eclipses of the sun. This is because a lunar eclipse can be seen from anywhere on the nighttime side of the Earth, while a solar eclipse is only visible along a narrow path on the Earth's surface.
The frequency of eclipses depends on the specific type of eclipse. On average, there are about 2-5 solar eclipses and 2-4 lunar eclipses per year that are visible from different parts of the Earth. So, you may not have to wait very long to witness an eclipse event.
On average, there are about 2-4 lunar eclipses each year. These can vary in type, with some being total eclipses and others being partial or penumbral eclipses.

There are eclipses of the sun (solar), and eclipses of the moon (lunar). At different places on the Earth, each of those may be total or partial. Sometimes only a partial eclipse is visible anywhere.
There are two general types of eclipses: solar eclipses and lunar eclipses. Solar eclipses occur when the moon passes between the sun and the Earth, blocking the sunlight. Lunar eclipses occur when the Earth passes between the sun and the moon, casting a shadow on the moon.
In general, there are two lunar eclipses and two solar eclipses each year. On average, about half are total and half are partial, so you can expect, over a span of years, to see one total lunar eclipse every other year. There are sometimes cycles of eclipses. In 2014-2015, there will be four sequential total lunar eclipses, with no partial eclipses in between; this cycle is called a "tetrad" and it isn't all that unusual. There will be eight such tetrads in the 21st century; this will be the second tetrad of the century.
the total numbers of an eclipses in one year is no more than seven
The time in between each eclipse can vary. There are approximately 2-7 solar eclipses every year and 2-5 lunar eclipses, but they don't happen at regular intervals. Solar eclipses are more rare to observe than lunar eclipses.
There are generally two lunar eclipses and two solar eclipses each year. Sometimes you will see two partial eclipses instead of one total eclipse; in 2011, there will be four partial solar eclipses, and no total or annular solar eclipses. Since lunar eclipses happen on the Moon, they are visible from the entire night half of the Earth. Solar eclipses, when the Moon's shadow hits the Earth, affect very small areas of the Earth, and so they seem to be more rare. The next total lunar eclipse will happen on December 21, 2010, and will be visible from any point in North America.
A lunar eclipse can occur multiple times a year, but the frequency can vary. On average, there are about two to four lunar eclipses each year. Lunar eclipses can be partial, total, or penumbral, with total eclipses being less common.
During the 100 years of the 20th Century, there were 228 solar eclipses and 229 lunar ones. So over the long term, you can figure on equal numbers, at the rate of around 7 of each every 3 years.
It varies. During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 229 lunar ones, for an average of about 2.3 per year. Any one year may have 2 - 5 of each.
Check the link to http://eclipse.gsfc.nasa.gov/eclipse.html. Looks like the last total eclipse of the Moon was on August 1, 2008. There are generally two solar eclipses and two lunar eclipses each year. Depending on the precise alignment of the Earth-Moon system, we sometimes get two partial eclipses instead of one of the total ones; 2009 is such a year. This year, we get three penumbral and one partial lunar eclipses.
