The Law of Moon Phase Changes
The law of the change of the moon phase children's song: the first day of the new moon is invisible, only because it is trapped in the sun and the earth; On the seventh day of the eighth month, half of the full moon faces west; The full moon appears in the fifteenth and fifteenth days, and the earth carries the sun and moon on its shoulder; Twenty-two or three last quarter moon, the moon faces east in the middle of the night. There was also the formula "Up, Up, West, Down, Down, East", which meant that the first quarter moon appeared in the first half of the lunar month in the middle of the night. The moon faced west and was located in the western half of the sky (the concave side faced east). The last quarter moon appeared in the second half of the lunar month in the middle of the night. The moon faced east (the concave side faced west) and was located in the eastern half of the sky. The novel New Moon is equally exciting. Everyone is welcome to click and read it!

Changes in the Moon Phase
The changes of the moon were generally divided into the stages of the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, waning moon, and so on. 1. New Moon (New Moon): On the first day of the lunar calendar, the moon moves between the earth and the sun. The back of the moon is illuminated by the sun and people on earth can't see it. The moon and the sun rose and set almost at the same time. 2. Crescent Moon: After the new moon, it appears around the third or fourth day of the lunar calendar. Shortly after the sun sets, a crescent moon shaped like an eyebrow can be seen in the western sky. The protruding part of the moon faces west, forming an inverted C shape. 3. ** First Quarter Moon **: Around the seventh day of the lunar calendar, it appears in the southwest sky in the middle of the night. From the northern hemisphere, the right half of the moon is illuminated, forming a semicircle. 4. ** Full and Convexed Moon (Gradually Full and Convexed Moon)**: Appears in the first half of the lunar calendar, around the eleventh and twelfth of each lunar month. Its shape is similar to that of a full moon, but it is slightly less full than a full moon because it is about to usher in a full moon. 5. ** Wang (Full Moon)**: On the 15th and 16th of the lunar calendar, the Earth is located between the Sun and the Moon. The side of the Moon facing the Earth will be illuminated, and the round moon will be visible all night. However, on the 14th, 15th, 16th, and even 17th of each lunar month, there might be a full moon. 6. ** Waning Convexed Moon (Waning Convexed Moon)**: Appears in the second half of the lunar calendar, around the 18th or 19th of each month. It is shaped like a full moon, but slightly less full than a full moon. Because the full moon has passed, it begins to wane. 7. ** Last quarter moon **: Around the 22nd of the lunar calendar, a semi-circular last quarter moon can be seen in the southeast sky in the second half of the night. From the northern hemisphere, the left half of the moon is illuminated. 8. ** Waning Moon **: At the end of the lunar month, the waning moon can be seen in the eastern sky at dawn. The protruding part of the moon faces east, like the letter "C". The moon's phase returned from the waning moon to the new moon and began a new cycle of changes.

Diagram of Moon Phase Changes
Diagram of the Moon Phase Changes
The law of the moon's phase change was: new moon (On the first day of the lunar calendar, the moon is located between the sun and the earth, so it is difficult to see the moon from the earth) → Emei Moon (On the third or fourth day of the lunar calendar, a thin silver hook-like moon can be seen in the western sky) → First Quarter Moon (On the seventh and eighth day of the lunar calendar, the moon can be seen in the middle of the night. It comes out from the west of the sky, and the moon faces west) → the crescent moon (The upper crescent moon appears on the 11th and 12th of each lunar month; the lower crescent moon appears on the 18th and 19th of each lunar month) → the full moon (on the 14th, 15th, 16th, or even 17th of each lunar month, the moon and the sun are on both sides of the earth, and the moon seen on earth is the roundest) → the last quarter moon (on the 22nd and 23rd of each lunar month, visible in the middle of the night, the moon faces east) → the waning moon → the new moon, and so on. The main reason for this was that the moon itself did not emit light and was not transparent. Moreover, the relative positions of the moon, the earth, and the sun were constantly changing, causing the parts of the moon that were illuminated by the sun to present different images.

Diagram of the changes in the moon phase of the watch
The cycle of the moon's phase was about 29.53 days, which was called a lunar month. The order of the moon's phase change was: New Moon, Crescent Moon, First Quarter Moon, Convex Moon, Full Moon, Convex Moon, Last Quarter Moon, Waning Moon, New Moon, and so on. On the watch, the moon phase function was a simulation of the changes in the moon phase. There were three common ways to display the moon phase on a watch: a single moon, a double moon, and a pointer moon. The most common one was a single moon. A single moon usually had a moon phase disk set at 6 o'clock or 12 o'clock on the dial, which appeared as a white moon that was blocked by the lower disk to form a crescent moon, but sometimes it would appear at different positions such as 10 o'clock or 2 o'clock. The bimonthly moon phase would have two moons, which was mainly designed to take into account the different appearances of the moons seen by the wearer in different positions in the northern and southern hemisphere. However, it was difficult to provide a special watch and moon phase change diagram based on the current reference materials. The novel New Moon is equally exciting.

The complete memory of the changes in the moon phase
The mnemonic chant for the changes in the moon's phase was "up, west, west, down, east." Its meaning was: the first quarter moon appeared in the first half of the lunar month in the first half of the night, the moon facing west (the concave side facing east), located in the western half of the sky (the concave side facing east); the last quarter moon appeared in the second half of the lunar month in the second half of the night, the moon facing east (the concave side facing west), located in the eastern half of the sky (the concave side facing west). There was also a song about the changes of the moon: "On the first day of the lunar month, the new moon cannot be seen, only because it is trapped in the sun and the earth. On the seventh day of the lunar month, the first quarter of the moon, half of the full moon faces west. The full moon appears at the age of 15 or 16, and the earth has the sun and moon on its shoulders. The moon faces east at the end of the night." The novel New Moon is equally exciting.

A summary of the law of the moon's phase change
Changes of the Moon Phase from the First to the Fifteenth
The changes of the moon from the first day to the fifteenth day were as follows: The first day of the first lunar month: This is the new moon, also known as the new moon. The moon moved between the earth and the sun. The back of the moon was illuminated by the sun, so people on earth could not see the moon. The moon and the sun rose and set almost at the same time. Starting from the second and third day of the lunar month: Shortly after the sun sets, a crescent moon shaped like an eyebrow can be seen in the western sky, which is the crescent moon. The protruding part of the moon faces west, forming an inverted C shape. Around the seventh day of the lunar month, the first quarter moon appeared in the southwest sky in the early night. From the northern hemisphere, the right half of the moon was illuminated, forming a semicircle. After that, until the 15th, a full moon would appear. Its shape was similar to that of a full moon, but it was slightly less full than a full moon. This was because the illuminated part of the moon facing the Earth was constantly increasing, gradually approaching the full moon. 15: It is called "Wang", also known as "Full Moon". Earth was located between the sun and the moon. The side of the moon facing the earth would be illuminated, and the round moon could be seen all night. The novel New Moon is equally exciting.

Changes in the moon's phase within a month
Within a month, the moon was generally divided into the stages of the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, waning moon, and so on. The first day of the lunar calendar was the new moon. The moon moved between the earth and the sun. The back of the moon was illuminated by the sun, so people on earth could not see it. The moon and the sun rose almost at the same time and set at the same time. After the new moon, a crescent moon would appear around the third or fourth day of the lunar calendar. Shortly after the sun set, a crescent moon shaped like an eyebrow could be seen in the western sky. The protruding part of the moon was facing west, forming an inverted C shape. The " first quarter moon " appeared around the seventh day of the lunar calendar. The first quarter moon would appear in the southwest sky in the first half of the night. From the northern hemisphere, the right half of the moon was illuminated, forming a semicircle. Around the 11th and 12th of the lunar calendar, there would be a "full moon". Its shape was similar to that of a full moon, but it was slightly less full than a full moon. Because it was about to usher in a full moon, it was also called a gradually full moon. The 15th and 16th of the lunar calendar was the full moon. The Earth was located between the sun and the moon. The side of the moon facing the Earth would be illuminated, and the round moon could be seen all night. Around the 18th and 19th of the lunar calendar, there would be a " waxing and waxing moon." This was the stage where the moon began to wane after the full moon. The " last quarter moon " appeared around the 22nd of the lunar calendar. In the southeastern sky in the second half of the night, a semi-circular last quarter moon could be seen. From the northern hemisphere, the left half of the moon was illuminated. At the end of the lunar month, a "waning moon" would appear. At dawn, it could be seen in the eastern sky. The protruding part of the moon was facing east, like the letter "C". After that, the moon returned to the new moon and began a new cycle of changes. The cycle of the moon's phase change was about 29.53 days. The novel New Moon is equally exciting.
