Becuse the orbit of the moon around the earth is tilted about 5 degrees from the orbit of the earth around the sun. Eclipses only happen around the time of year when the mon, sun, and earth are colinear. It is in March and October when the moon passes through the plane of the earth's rotation. At all other times of year, the earths shadow or the moon's shadow fall past the other body. You need a new moon at the right time of year for a soalr eclipse (moon between earth and sun) or a full moon at the right time of year for a lunar eclipse (earth's shadow falls on the moon).

If you mean... why isn't there a solar eclipse during every new moon, the moon doesn't fall into alignment on every new moon. The moon's orbit around the earth is not in the same plane as the earth's orbit around the sun. Check out this link:

There is either a partial or full eclipse every time the moon passes between the earth and the sun.

because maximum circumstances the Moon is going slightly north or south of precisely between the Earth and solar. yet about 2 circumstances a year it strikes precisely between, and the shadow of the moon falls on earth.

It has to be in an exactly precise spot for an eclipse to occur and the orbits are not that perfect.
