Lunar phase - Wikipedia
Because the Moon is tidally locked to Earth, the cycle of phases takes one lunar month and moves across the same side of the Moon, which always faces Earth. In common usage, the four major phases are the new moon, the first quarter, the full moon, and the last quarter.

Lunar Phases: The 28-Day Cycle of Light and Shadow
By observing the Moon’s phases, we gain insight into the mechanics of orbits, the behavior of light, and the relationships between celestial bodies. The cycle has also played a crucial role in human history. Many early calendars were based on lunar phases, using the Moon as a natural timekeeper.
