The Waning Gibbous phase: After the greatest phase of a full moon, the brightness begins to diminish, which is known as the waning gibbous phase. This phase will remain till the end of the third quarter. The lights gradually fade after the third quarter until the New Moon, when they are fully gone. This is the phase of the declining crescent.
The waning gibbous phase starts at midnight on the night of the full moon and lasts 30 days.
The waning gibbous phase ends at midnight on the night of the new moon.
This phase is related to birth processes and the ending of life cycles. It is believed that if someone has an illness or injury that prevents them from being able to see their own shadow, then they can still be alive during this phase.
People who are alive during the waning gibbous phase will experience changes in their environment due to the presence of this invisible body. They will be able to see the night sky as bright with stars as ever, but the moon will look different. Instead of seeing a full moon, they will see a waxing gibbous moon that grows smaller each day until it is completely vanished at the beginning of the next lunar cycle.
In some cultures, people believe that during this phase you can communicate with ghosts, so this knowledge could help survivors get through these periods safely.
Which moon phases can we view during the day? Except for the fresh and complete phases, you can see them all. During the day, you may view the following phases: waxing crescent, first quarter, waxing gibbous, waning gibbous, last quarter, and waning crescent.
You cannot see the full moon during the day, but if it is visible from where you are, it will appear half-silvered by sunlight reflected off of Earth's atmosphere. The word "half-moon" comes from this phenomenon.
The crescent Moon appears as a thin, curved shadow that grows longer as the Moon waxes (increases in size). Since the curve is opposite that of the Earth, near the horizon, the end of the shadow points down south (unless, of course, the Moon is rising or setting). The beginning of the shadow points up north. At its closest approach to the Earth (about 30 miles), the crescent Moon passes through the center of our planet's shadow. Everywhere on Earth other than at the poles, daytime temperatures fall by about 5 degrees Fahrenheit.
At its most distant (about 510 miles), the crescent Moon disappears behind the Earth's edge. From there on out, night falls again until the next new moon.

Full 7. The moon is rising or setting when it passes the western half of the horizon plane (circle one). 8. The moon is rising or setting when it passes the eastern side of the horizon plane (circle one). 9. The moon is either rising or setting when it reaches its zenith (highest point).
10. The moon is either rising or setting when it reaches its nadir (lowest point). 11. The moon is rising when it enters a new phase from west to east. 12. The moon is setting when it enters a new phase from north to south. 13. The moon is neither rising nor setting when it crosses the center of the sky.
14. The moon is either rising or setting when it reaches its highest point after midnight. 15. The moon is either rising or setting when it reaches its lowest point before midnight.
16. The moon is rising when it is first seen in the morning sky and setting when it is last seen at night.
17. The moon is rising when it leaves the southeast and setting when it enters the southwest.
18. The moon is rising when it reaches its greatest distance from the Earth and setting when it comes closest to the Earth.
However, it seems to rise and set as a result of the Earth's revolution on its axis. Every 24 hours, one complete turn is completed. It takes a left turn and heads east. The sun appears to be going west while the Earth rotates toward the east. This is called "apparent motion." Night falls when the sun is west of the Earth, not when it is directly over the center of the planet.
The Earth's axial rotation causes the daily cycle of light and darkness to occur even if nothing moves. If we were living on the surface of the Earth, we would see the Sun rise every morning in the east and set every evening in the west. But since we live in a spaceship, we need some kind of device to tell us what time it is. The Earth's shadow is about 30 miles long, which is why we get daytime and nighttime cycles even if nothing is moving. Even though we aren't walking around, the Earth's shadow still sweeps across the face of the planet each day.
We call this mechanism that tells us what time it is "clock". A clock uses an object that moves back and forth like the hands of a watch or timer. However, a clock needs something to measure off these swings - something that can mark different times. In the case of a traditional mechanical clock, these different times are marked by the passage of water or oil through a system of rotating wheels or gears.
