Yes that is how scientists know when the next solar or lunar eclipse will be. this is due to the rotation of the earth around the sun...
Lunar phases lasts about 3 1/2 days. The moon doesn't change phases fast enough to change on a nightly basis. It takes several days.
It changes continually in time with its orbital motion.
You can use the preposition "during" for lunar phases. For example, you can say "during the lunar phases" to refer to the various stages of the moon as it cycles through its different shapes.

There is no "most common" lunar phase. The moon phases occur regularly on a 28/29 day basis so all phases are equally common as each other.
The lunar orbit, or maybe more precisely, the mutual earth-moon orbit.Orbit
The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.
Lunar phases are tightly related to both kinds of eclipse: -- A lunar eclipse can occur only at the time of Full Moon. -- A solar eclipse can occur only at the time of New Moon.
it is caused by the reflection of light
Moon phases and lunar eclipses both deal with the earth. They are deal with both the sun and the earth.
The word "lunar" in English refers to anything related to the moon, such as lunar phases or the lunar surface.
Not only the earth's rotation , the lunar phases change cyclically as the Moon orbits the Earth, according to the changing positions of the Moon and Sun relative to the Earth.
