This is not necessary. Solar eclipse occurs when moon is between the sun and earth and lunar(new moon day) eclipse when earth is between sun and moon(full moon day). Moon takes around 29 days for a rotation so gap is minimum 14 days.

The reason we don't have eclipses every new and full moon is that the moon's orbit is tilted about 5° relative to the Earth's orbit around the sun. There are two points, called nodes, where the moon's orbit crosses the plane of Earth's orbit. If the new moon is close enough to a node, the moon comes directly between Earth and the sun and we have a solar eclipse. When the full moon is close to a node, the Earth is directly between sun and moon and we see a lunar eclipse. The nodes move very slowly, so a full moon and the next new moon are often each close enough to one of the two nodes to have an eclipse. It can also happen the other way around, with a solar eclipse following a lunar eclipse.

A lunar eclipse occurs during a full moon, when the earth is between the sun and the moon. A solar eclipse occurs during a new moon when the moon is between the sun and the earth. A full moon and a new moon are about 2 weeks apart.

Two weeks means 14 days. The moons takes 15 days to revolve halfway around the Earth.This keeps it opposite its initial position.When lunar eclipse occurs, the moon will be at one end and the sun will be at onother.This means that the moon, before 15 days, was between the sun and the earth (solar eclipse)

Because it takes the Moon about 2 weeks to orbit half-way around the Earth ☺
