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.

The sequence of changes in the moon's phase within a month was: new moon (Also known as New Moon, the first day of the lunar calendar, when the moon is not visible on Earth) → Emei Moon (The moon rises after sunrise and sets after sunset. It is in the sky with the sun. It is not easy to see it in the bright sky. It can only be seen in the western sky for a period of time after the sun sets.) → The first quarter moon (On the seventh and eighth day of each lunar month, observers on Earth see the western half of the moon bright, facing west, in a semicircle shape. The moon rises at noon in the middle latitudes of the northern hemisphere, appears in the south sky at dusk, and falls below the horizon from the west at midnight) → (The crescent moon is gradually rising, around the ninth day of the lunar calendar to the fourteenth day of the lunar calendar. More than half of the west is illuminated by the sun. After noon, the moon rises. At dusk, it is in the southeast sky. The moon faces west and then continues to move west. It sets from the western horizon before dawn and can be seen in the middle of the night.) → Full Moon (Also known as Wang, on the 15th and 16th of the lunar calendar, the sun and moon collide. The moon moves to the outer side of the earth, and the sun and moon are on both sides of the earth. Usually, the earth cannot block the sunlight, and the bright side of the moon is all facing the earth.)(Waning and protruding moon, around the 16th-23rd lunar calendar) → Last quarter moon (Around the 22nd and 23rd of the lunar calendar, the relative positions of the sun, the earth, and the moon are at right angles again. The moon is 90 degrees west of the line between the sun and the earth. The eastern half of the moon is bright in a semicircle. The moon faces east. It rises above the eastern horizon at midnight and hangs high in the southern sky at dawn. It sets from the western horizon at noon and can be seen in the second half of the night.) → Waning Moon (around the 24th of the lunar calendar to the end of the month) → New Moon (the first day of the lunar calendar).

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!

The moon's phase was based on the different positions of the Earth, the Moon, and the Sun. The part of the moon that was illuminated on Earth changed periodically, showing various round and waning shapes. The following is a rough picture of the moon with dates (based on the lunar calendar): The first day of the lunar calendar: New Moon. At this time, the moon is between the sun and the earth. We can hardly see the moon. From the third to the fourth day of the lunar calendar, the crescent moon was visible in the western sky after sunset. From the seventh day to the eighth day of the lunar calendar, the first crescent moon, its bright face facing west, rises at noon and sets in the middle of the night. Half of the moon can be seen illuminated. Lunar calendar 12 to 13: The moon is gradually full, most of the moon is illuminated, and the bright part gradually increases. The fifteenth to sixteenth of the lunar calendar: Full Moon. The Earth is located between the sun and the moon. The entire moon is illuminated and visible all night. From the 18th to the 19th of the lunar calendar, the crescent moon gradually waned, and the bright parts began to decrease. Lunar calendar 22 to 23: The last quarter of the moon, bright facing east, rises at midnight, sets at noon, and you can see half of the moon illuminated. The waning moon appeared in the eastern sky before dawn. It was a thin crescent moon that gradually transitioned to a new moon. The novel New Moon is equally exciting.

The following is a method to draw the moon phase: 1. First, he drew two circles, one big and one small. The small one represented the Earth, and the big one represented the orbit of the Moon. 2. With the help of a ruler, he drew a line inside the circle that represented the moon's orbit. 3. Find a bottle cap and draw eight small circles at the intersection of the Mi line and the outer circle. These small circles represent the moon. 4. According to the changing law of the moon, he drew the shape of the moon at different stages, including the new moon, the Emei moon, the first quarter moon, the upper bulge moon, the full moon, the lower bulge moon, the last quarter moon, and the waning moon. He also noted the corresponding names on them. 5. Finally, he could color it according to his preferences. The moon's phase changed because the moon revolved around the earth, and the earth revolved around the sun. The relative positions of the sun, earth, and moon changed, causing the shape of the moon to change from the earth's perspective. When the moon was in the middle of the earth and the sun, it was a new moon. As the moon slowly moved around, the moon was not completely " backlit " and began to gradually reveal some light. When it was curved like an eyebrow, it was called a crescent moon. When it was exactly half bright, it was called a crescent moon. When it was about to be fully bright, it was called a full moon. When the earth was between the moon and the sun, it was a full moon. After the full moon, the moon would slowly cover the part of its light, and the " waxing moon "," waning moon ", and " waning moon " would appear until the next new moon arrived.
