Solar eclipse takes place on

Hint: As first step, you could give a good explanation on solar eclipse by listing down the terrestrial bodies taking part in it. Also, another significant point to be mentioned would be the conditions associated with the event. After this, you could give the day on which we could observe a solar eclipse.

Complete step-by-step solution:
In the question we are asked to find the day when a solar eclipse takes place. In order to answer this question, we are supposed to have a basic understanding of the concept of solar eclipse.
A solar eclipse is known to occur when a portion of the Earth gets engulfed in the shadow that is cast by our own natural satellite, the Moon that is responsible for blocking the sunlight partially or fully. Another necessary condition for the event to occur is the alignment of the Earth, the Sun and the Moon.
We could have had total solar eclipses for every new moon if moon’s orbit was perfectly circular. So another necessary condition demands the moon to be close enough to the ecliptic plane during a new moon.
So, if we are asked to give day for this event of solar eclipse, we could say that it takes place on a New moon day. But we should remember that not every new moon day promises you a solar eclipse and this has to do with the moon’s orbit.

Note: In the olden times, eclipses, be it solar or lunar were associated with bad omens as well as supernatural causes. However, now with the advance of science, we know that it is simply a natural phenomenon and has nothing to do with bad omens. However, this misconception is justified by the understanding of the fear that could awaken in people without astronomical knowledge for the sun disappearing during the day by darkening the sky for a few minutes.
