A solar eclipse occurs on a new moon day.
True
Solar eclipse occurs on a new moon day when the moon is in between the earth and the sun. An observer on the earth can not see Moon because its illuminated part is facing away from us. A solar eclipse occurs when Moon comes in between Earth and Sun and three celestial objects should be almost in a straight line. Solar eclipse occurs only when the moon is in between Earth and Sun, so it can happen only on a new moon day.
