Total lunar eclipses occur between 0-3 times per year.
There are two lunar eclipses in most years; however, there can be anywhere from zero to three in any given year.
There are at least two partial lunar eclipses per year.
Once every 33 months
The "next" one of anything is a continually moving target. Any set answer will be out of date when the "next" event occurs. For the date and parameters of the "next" eclipse, check the NASA Eclipse page (at the link below) to see the particular details for any eclipse between the years 2000 BCE to 3000 AD._________________________________________________________ AnswerThe next total lunar eclipse is December 21, 2010, and will be visible from anywhere in North America.According to Astronomy Essentials and Earth Sky, the next lunar eclipse should arrive on April 25th, 2013. It's only a partial eclipse, and it will only last 27 minutes.
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.
2 Every Year.
Typically, lunar eclipses occur once or twice a year. Because more than half of all lunar eclipses are partial, and because lunar eclipses are visible only from the side of the Earth where the Moon is up, you would generally be able to see a total lunar eclipse every other year or every 3rd year from your location. The rest of the eclipses would be either partial, or not visible from your location. You can check the NASA Eclipse Web Page to see the catalog of all eclipses from 2000 BCE to 3000 AD at the link below.

4.1 Solar eclipse; 4.2 Lunar eclipse
Lunar eclipses can happen a maximum of twice per year, and only at the time of the full moon. Sometimes the alignment is just right, and we get a total lunar eclipse. If the alignment isn't exact, we might get a partial or a penumbral eclipse instead of a total eclipse.
They are about equal in number. The difference is in how many people SEE the eclipse. During a solar eclipse, only people along the path of totality can see the eclipse, and that's a pretty narrow track. For a lunar eclipse, everybody on the night side of the Earth can see it.
none to 3 lunar eclipses a year
If the moon's orbital plane coincided with the earth's orbital plane, there would still bea maximum of one lunar eclipse and one solar eclipse in each lunar cycle.The difference would be that they would occur in everylunar cycle. We would have a totaleclipse every two weeks, with lunar and solar alternating.And that would just be the natural order of things. We wouldn't think any more about itthan we marvel today at the rising and setting of the sun.
about 5 times a year, during the new moons
During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 13 times lunar eclipses.
Well if its a lunar eclipse with a full moon on a solctice then it is 84 years. I dont know about a reagular lunar eclipse though.

If the orbit of the Moon was level with the orbit of the Earth around the Sun, there would be a solar eclipse at every new moon, and a lunar eclipse at every full moon.
About 2. The lunar tidal cycle is 12 hours & 25 min. (Note that not all tides are lunar.)
