why there is no solar or lunar eclipse at full and new moon day?

if you mean like a new moon (solar eclipse) <every new moon, and a full mooon (lunar eclipse) <every full moon:\n\nbecause the earth and moon are not on the same plane, and the moon is in a higher altitude than earth, and the moon only crosses sometimes into the earth's plane with the sun.

new moon, not fullmoon.

I would expand this to say that a lunar eclipse occurs when the earth is positioned directly between the sun and the moon, and their plane of orbits align.\n\nThe last point is critical because you could easily wonder why we don't have lunar eclipses every month when the moon's orbit is such that the earth is in the middle... because the order of the planets is not only important, but that they line up just exact so that the earth's shadow does not fall just above or below the moon, but directly on it.

First, you must picture in your mind the 3 celestial bodies: sun, earth and moon. Picture the moon circling the earth: now it is between the earth and the sun, now it is at the other side of the earth, now it comes back again between earth and sun... As you know it takes about 4 weeks for the moon to make an entire circle around the earth.\nWhat happens when the moon is between us and the sun? well, it receives light from the sun on the face that is turned that way, so  we can't see it at the moment. That's why we can't see the new moon! It's there is the sky, but not lighted in the side facing us!\nThen 2 weeks later the moon is on the opposite side. The face that is facing the sun - and reflecting all that sunlight - is also facing the earth! So we see it fully - full moon.\nBut the path of the moon is not entirely on the same plane as us and the sun, there is a slight angle!!  Only sometimes it happens that the shadow of the earth catches the moon when it's full (and when it is perfectly aligned with the earth and the sun). THAT's your eclipse!!

A total solar eclipse will just graze the island on June 13, 2132.  Needless to say, don't hold your breath.  :(\n\nHere's a great page with lots of eclipse data:\n\nhttp://sunearth.gsfc.nasa.gov/eclipse/solar.html

One of the biggest misconceptions about the Moon is that its phases are caused by the Earth's shadow. The Earth's shadow causes eclipses, but it has nothing to do with phases. Rather, the phases of the Moon are produced by the alignment of the Moon and the Sun in the sky. \nThe orientation of Sun and Moon determines the phase of the Moon. At new moon, the angular distance of the sun and moon is small, less than a few degrees. At first quarter, when the moon is half full, the Moon lies 90 degrees east of the Sun. As an example, if you were to point to the setting sun with one arm and to the moon with the other, the angle between your arms would be 90 degrees. At full, the moon is 180 degrees from the sun and at last quarter, it is 90 degrees west of the sun. \n \n\nThe new moon is essentially invisible because it is between the earth and sun and therefore lost in the glare of the sun. Even on day 2 or 3 it is tough to spot the moon because it is just the tiniest sliver and still very close to the sun. The waxing crescent moon grows till it is about half full in the phase we call first quarter. From there it grows to full moon and then begins to shrink back to third quarter, waning crescent and finally back to new moon. \n\nThe first and last quarter moons mark the halfway points between the new moon and full moon. The first quarter moon is illuminated on the right hand side. The last quarter moon is illuminated on the left hand side. It seems conflicting to call a half full moon first of last quarter, but the quarter refers to the position of the moon in the sky, not it's phase. A quarter moon is one quarter of a full circle (90 degrees) away from the sun. \n\nThe lighted part of the Moon always points the way to the Sun. This means that a waxing crescent moon in the western sky at sunset has the lighted part on the right which is the direction of the Sun. The sequence of the lunar phases always proceeds with the lighted part of the Moon growing from right to left until the moon reaches full. After full moon, the light recedes from right to left until new moon. \n\nThe line boundary between dark and light on the Moon is called the terminator. It is rarely an even line because the surface of the Moon is not smooth. The terminator is closest to a straight line at first and last quarter. Librations affect exactly what portion of the face of the Moon is facing the Earth, during first and last quarter phase, the terminator's exact location may vary. This is illustrated when the terminator does not line up with the Moon's meridian at first and last quarter. In other words, you'd think that during first and last quarter when the Moon is half full, that the meridian (the imaginary line which runs from north to south on the Moon,) would be right on the terminator, but it isn't so. In fact the terminator can be almost 8 degrees off to either side of the meridian.

They are not the same.  During a full solar eclipse, the moon's shadow is only a spot on earth because the moon is much smaller than the earth, you have to be inside that spot on earth to see the full solar eclipse.\n\nDuring a full lunar eclipse, the earth's shadow covers the entire moon, and you don't see the moon no matter where on earth you are.

the moon is always there, but it is probably a new moon, a phase of the moon where the sun doesn't shine light on it at the popsition that we can see it. The other stages include combinations of waning, waxing & gibbious and cresent

Beijing, China will see a total solar eclipse on Saturday, September 1, 2035; Tokyo will just miss totality with 99.5% of the sun obscured.\n\nBefore Tokyo's next total solar eclipse, the city will see three annular solar eclipses (April 7, 2312, October 23, 2386, and August 4, 2502).  Then, on Saturday, August 11, 2762, the sun will be fully covered by the moon for an impressive 6 minutes and 14 seconds.

The full moon did appear very big this month, but that is because of its location relative to the horizon.  The full moon was at its lowest zenith of the year.  Yes, it's technically an optical illusion, but that technicality doesn't make the view any less impressive.\n\nJust as the Sun passes over more Northern latitudes (at least up to the Tropic of Capricorn) in the summer and more Southern latitudes in the winter (to the Tropic of Cancer), the Moon also varies in its elevation.  Except the Moon passes over more Southern latitudes in the summer and more Northern latitudes in the winter.

There are three types of Lunar Eclipse. Penumbral Lunar Eclipse,Partial Lunar Eclipse, and Total Lunar Eclipse.\n\nPenumbral Lunar Eclipse\nThe Moon passes through Earth's penumbral shadow. These events are of only academic interest since they are subtle and quite difficult to observe\nPartial Lunar Eclipse\nA portion of the Moon passes through Earth's umbral shadow. These events are easy to see, even with the unaided eye\nTotal Lunar Eclipse\nThe entire Moon passes through Earth's umbral shadow.\nThese events are quite striking for the vibrant range of colors the Moon can take on during the total phase(due to refracting light thru the earths atmosphere)\nIf the Moon orbits Earth every 29.5 days and lunar eclipses only occur at Full Moon, then why don't we have an eclipse once a month during Full Moon?.The Moon's orbit around Earth is actually tipped about 5 degrees to Earth's orbit around the Sun. This means that the Moon spends most of the time either above or below the plane of Earth's orbit. And the plane of Earth's orbit around the Sun is important because Earth's shadows lie exactly in the same plane. During Full Moon,the moon usually passes above or below Earth's shadows and misses them entirely. No eclipse takes place. But two to four times each year, the Moon passes through some portion of the Earth's penumbral or umbral shadows and one of the above three types of eclipses occurs.

This question could be very easily answered by looking up solar eclipses somewhere such as Wikipedia. \n\nA solar eclipse happens when the moon passes between the Earth and Sun, causing people on Earth to be completely or partially unable to see the sun, because the moon is in the way. This is able to happen in spite of the fact that the moon is much smaller than the sun, because while the sun is about 400 times bigger than the moon, it is also 400 times farther away from the Earth than the moon is. \n\nThe reason that a solar eclipse can only happen during the new moon is that the new moon phase is the only time when the moon is in between the Earth and Sun at all.

New Moon - The Moon's unilluminated side is facing the Earth. The Moon is not visible (except during a solar eclipse).\nWaxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing.\nFirst Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing.\nWaxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing.\nFull Moon - The Moon's illuminated side is facing the Earth. The Moon appears to be completely illuminated by direct sunlight.\nWaning Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing.\nLast Quarter - One-half of the Moon appears to be illuminated by direct sunlight.

full moon.  a lunar eclipse occurs when the earth blocks the light from the sun, so the earth is positioned between the sun and moon - the full moon phase.

A full moon is simply fully visible.  Usually, the earth is between the sun and the moon to some degree.  The curved shadow on the moon is the shadow of the earth.  A full moon is when the moon is slightly to the side of the earth and the sun is shinging on the entire surface with no shadow of the earth on it.\n\nSee the link below for a good explanation.
