What is the "up and down" in the moon phase? What are they?

In the lunar calendar, "going up to the west and down to the east" is a formula of the lunar calendar, which is convenient for memory. It means:

"Up to the west" means that the first quarter moon appears in the first half of the lunar calendar, facing west and located in the western half of the sky.

"Last quarter moon" means that the last quarter moon appears in the second half of the lunar calendar, facing east and located in the eastern half of the sky.

Moon phase, astronomical terminology. In astronomy, it is the name of the part of the moon that is illuminated by the sun as seen from the earth.

Moon phase change law

1. On the first day of the lunar month, the moon lies between the sun and the earth. People on earth only see the moon deviating from the dark side of the sun, so they can't see the moon on earth (equivalent to the "black moon"), which is called a new moon or a new moon. This moon phase almost rises and sets with the sun, that is, it rises in the morning and sets at dusk, and its existence can only be detected during the solar eclipse.

2. After the new moon, the moon rotates eastward around the earth, leaving the middle between the earth and the sun and leaning to one side, that is, the moon is located in the east of the sun. The half moon illuminated by the sun faces west. On the earth, we can see that part of it is sickle-shaped, and the convex surface faces the western sun, which is called the moth eyebrow moon.

Moths rise after sunrise and set after sunset. She and the sun are in the sky, in the bright sky, so she can't see the moon phase. Only after sunset can you see the moth-eyebrow moon in the western sky.
