How many eclipses are there in a calendar year?
The answer very much depends on the year. One calendar year has a minimum of four eclipses, which are two solar eclipses and two lunar eclipses. A year can have as many as seven eclipses. So each year is different.
How often are lunar eclipses in the northern hemisphere?
The hemisphere is irrelevant. Lunar eclipses happen, over the long run, about one and a half times a year or so for partial or total lunar eclipses. (if we add penumbral eclipses also, they're a bit more common, but you need special equipment to detect a penumbral eclipse... you can't really tell visually). Lunar eclipses are visible from the entire dark half of the Earth, while solar eclipses are visible only along a narrow path. This makes it SEEM as if solar eclipses are rare, but they are only rare for a specific location. The NASA Eclipse Web Page has a listing of all eclipses from 2000 BCE to 3000 AD. Because a lunar eclipse lasts for some time, a bit over half the Earth gets to see any given one. You can reasonably expect to see slightly under one lunar eclipse per year.
How many lunar eclipse does earth experience each year?
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.
How many years is it between a lunar eclipse?
In the 100 years from 1901 to 2000, there were 228 solar eclipses and 229 lunar ones.So over a long period of time, that's an average of roughly 2.3 of each kind every year.There are typically 2 or 3 of each kind every year. But some years have only one, andoccasionally there can be a year with as many as five.There are generally two lunar eclipses each year. Of those, about half are partial or penumbral, and a lunar eclipse is visible from about one-half of the world. So wherever you live, you can expect to experience one total lunar eclipse about every other year.Depending on the precise alignment of the Sun, Moon and Earth, a lunar eclipse can take anywhere from a few minutes (for a partial eclipse) to three or four hours, from beginning to end.
In how many years does a full lunar eclipse appear?
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.

How often do eclipses happen in Moon and Sun?
About one or two solar eclipses per year, and one or two lunar (Moon) eclipses per year, on average. Go to NASA.com and search it. there will be a map with the spots of eclipses and time/year.
What was the last lunar eclipse?
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.

Can are lunar eclipse be shown 3 times in are year?
There are different numbers of lunar eclipses in different years. I think five (5) is the maximum possible in one year.

How often are total lunar eclipse cycles?
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.

How many lunar eclipse is a day?
Lunar eclipses can occur up to three times a year, but there is never more than one lunar eclipse on a single day. This is because a lunar eclipse happens when the Earth is directly between the Sun and the Moon, which can only occur when the Moon is full. Thus, while multiple lunar eclipses can happen within a year, they are limited to one per day.
What was the last eclipse?

Is it true that a lunar eclipse happen every 400 years?
No. There are generally two solar eclipses and two lunar eclipses each year. This year, 2013, has two solar eclipses and three lunar eclipses. However, the area of the Earth affected during a solar eclipse is pretty small, so there are long periods between two eclipses in the same location. But it isn't a uniform period. For example, there will be total eclipses of the Sun twice in 7 years, in 2017 and 2024, in an area around Carbondale, Illinois. For other locations, there haven't been any total solar eclipses in a couple of hundred years. You can see the 5,000 year catalog of all eclipses between 2000 BCE and 3000 AD on the NASA Eclipse web page at the link below.
