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 Phase
The phase of the moon refers to the different positions of the Earth, the Moon, and the Sun. We see the various round and waning shapes of the illuminated part of the moon on Earth. The reason for this was that the moon itself did not emit light and mainly relied on reflecting sunlight. When the moon revolved around the earth, the relative positions of the earth, the moon, and the sun constantly changed regularly, allowing observers to see the parts of the moon illuminated by the sun from different angles, thus forming different moon phases. The phases of the moon were generally divided into the stages of the new moon, crescent moon, first quarter moon, full crescent moon, moon, waning crescent moon, last quarter moon, and waning moon. The first day of the lunar calendar was the new moon. At this time, the moon was between the earth and the sun. The back of the moon was illuminated by the sun, so the moon could not be seen on earth. The moon and the sun rose and set almost at the same time. After the new moon, shortly after sunset, the crescent moon 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 was around the seventh day of the lunar calendar. It appeared in the southwest sky in the early night. From the northern hemisphere, the right half of the moon was illuminated and formed a semicircle. 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 was illuminated and could be seen all night. Around the 22nd of the lunar calendar was the last quarter of the moon. It appeared in the southeast sky in the second half of the night. From the northern hemisphere, the left half of the moon was illuminated. At the end of the lunar calendar, the waning moon appeared in the eastern sky at dawn. The protruding part of the moon faced 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 29.53 days. This cycle was called the lunar month. It was the source of the calendar months and weeks. 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.

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!

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.

The Memory Formula for the Changes of the Moon Phase
The mnemonic chant for the changes in the moon's phase was "up, west, west, down, east." The meaning was that the first quarter moon appeared in the first half of the lunar month, with the moon facing west (with its concave surface facing west) and located in the western half of the sky; the last quarter moon appeared in the second half of the lunar month, with the moon facing east (with its concave surface facing east) and located in the eastern half of the sky. There is also a song about the change of the moon: The new moon is invisible on the first day of the month, only because it is trapped in the sun and the earth; On the seventh and eighth day of the first quarter of the month, half of the full moon faces west; The full moon comes out at the fifteenth and fifteenth days, and the earth carries the sun and moon on its shoulder. On the twenty-third quarter of the month, the moon faces east in the middle of the night. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
Moon Phase Changes, Year Two
The changes of the moon were generally divided into new moon, crescent moon, first quarter moon, full moon, full moon, waning crescent 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. On this day, the moon and the sun rose almost at the same time and set at the same time. 2. Crescent Moon: After the new moon, the moon rises later and later. Soon after the sun sets, the crescent moon that looks like an eyebrow can be seen in the western sky. The protruding part of the moon faces west, forming an inverted C shape. It probably appears on the third or fourth day of the lunar calendar. 3. ** First Quarter Moon **: Around the seventh day of the lunar calendar, the first quarter moon will appear in the southwest sky in the first half of the night. From the northern hemisphere, the right half of the moon will be illuminated, forming a semicircle. 4. [Full and Convex Moon]: Appears around the eleventh or twelfth of the first half of the lunar calendar. It is shaped like a full moon, but slightly less full than a full moon. Because a full moon is about to arrive, it is also called a gradually full and concave moon. 5. ** Full Moon (Wang)**: At 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. 6. ** Waning Convex Moon **: Appears around the 18th and 19th of the second half of the lunar calendar. It is shaped like a full moon but not as full as a full moon. It is also known as a gradually waning Convex Moon. 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 changed from a waning moon to a new moon, and it began a new cycle. If one wanted to draw a moon phase change map for a second grade student, they could simply follow the above order. They could use a simple circle to represent the moon, the illuminated part would be represented by white or yellow, and the unilluminated part would be represented by black. The corresponding lunar date and moon phase name would be marked next to it. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
The law of the moon's phase changes
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.
