Question

Why solar eclipse does not take place on each no moon day?

Answer 1

Heya mate here is ur answer...
An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon's shadow happens to fall upon Earth's surface at that time, we see some portion of the Sun'sdisk covered or 'eclipsed' by the Moon.So it doesnot occur in no moon day.
hope it may helpful...

Answer 2

Eclipses take place when the moon is located within 0.5  degrees on the ecliptic plane in a position when the sun, earth and the moon all lie in a straight line.

So only when the moon passes through the ascending and the descending nodes, eclipse is likely to occur.

Solar eclipse occurs only on a new moon day when the moon is adjacent to one of these nodes.

That is why solar eclipse does not take place in every new moon day.
