Understanding the Moon Phase Change Formula
The incantation of the moon's phase change was 'up, west, west, down, down, east.' The understanding of "Shang Xi Xi" was as follows: the first "Shang" meant the first quarter of the moon, the second "Shang" meant the first half of the moon, and the third "Shang" meant the first half of the night. "Xixi" meant that the crescent moon appeared in the western half of the sky, and the moon was facing west (that is, the western half of the moon was bright, and the concave side was facing east). The first "Xia" referred to the last quarter of the moon, the second "Xia" referred to the second half of the moon, and the third "Xia" referred to the second half of the night. "Dongdong" meant that the last quarter of the moon appeared in the eastern half of the sky, and the moon faced east (that is, the eastern half of the moon was bright, and the concave side faced west). The moon's phase change was due to the moon's movement around the earth, causing the relative positions of the sun, the earth, and the moon to change regularly throughout the month. Because the moon itself does not emit light and is not transparent, only the part of the moon that is directly illuminated by the sun can reflect sunlight. We can see the different conditions of the part of the moon that is directly illuminated by the sun from Earth, which forms the change of the moon phase. This formula helps to determine the date, time and position of the moon phase according to the moon phase. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
Elementary School Moon Phase Change Rule Formula
The law of the moon's phase change was as follows: " The new moon cannot be seen on the first day of the lunar month because it is trapped in the sun and the earth. The first quarter moon on the seventh and eighth day of the lunar month faces west. The full moon appeared in the 15th or 16th of the lunar month, with the sun and moon on the earth's shoulder. The last quarter moon appeared in the 22nd or 23rd of the lunar month, with the moon facing east and the second half of the night. There were also the words " up, west, down, east, west, east, east, west, west, west The novel New Moon is equally exciting. Everyone is welcome to click and read it!
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 change animation
The animated demonstration of the changes in the moon phase helped to better understand the changes in the moon phase. In the moon phase animation, a fixed space background would usually be displayed. The moon would move in the background as the date changed, and bright colors would be used to represent different moon phase states. For example, a full circle represented a full moon, and a full black represented a new moon. The moon phase changes can be divided into eight different states, including the new moon.(The sun shines on the dark side of the moon, and the moon is completely unlit and appears black), Emei Moon (the moon begins to be illuminated by the sun's rays, and the moon appears a slender arc), Second, Third, Fourth, First Quarter Moon (the left edge of the moon is strongly illuminated, and the moon moves the fastest during the change of the moon's phase), Reunion Moon (also known as the full moon, and the moon appears to be completely round), and Last Quarter Moon (the right hemisphere is illuminated by the sun's rays). Every month, there were four distinct changes in the moon's phase: the moon was completely covered by the sun at the new moon, and the moon could not be seen. At the first quarter of the moon, only half of the moon was illuminated by the sun, forming a semicircle. At the full moon, the moon was completely illuminated by the sun, forming a circle. At the last quarter of the moon, only half of the moon was illuminated by the sun, forming a reverse semicircle. In addition, the change of the moon's phase was affected by the position of the Earth, the Sun, and the Moon. It was also affected by the shape and surface of the moon itself. For example, the pits on the surface of the moon would make the moon appear irregular. Observing in the northern hemisphere, the moon was below the sun at the new moon, west of the sun at the first quarter and full moon, and east of the sun at the last quarter. Observing in the southern hemisphere, the position and appearance were opposite. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
The relationship between the moon phase change map and the moon phase name
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. In the Moon Phase Change Map, each phase corresponded to a specific moon phase name. During the new moon, the moon moved between the earth and the sun, with its dark side facing the earth and rising and setting with the sun. This stage was at the starting position in the lunar phase change map, and the moon could not be seen. The crescent moon appeared after the new moon. Its shape was curved like an eyebrow, and the protruding part of the moon was facing west in an inverted C shape. It was the transition form of the new moon to the upper and lower quarter moon. The first quarter moon appeared around the seventh day of the lunar calendar. From the northern hemisphere, the right half of the moon was illuminated, forming a semicircle. At this time, the line connecting the sun and the earth was vertical to the line connecting the earth and the moon. It was located in a specific transition position in the moon phase change map. The full moon was between the first crescent moon and the full moon, and the illuminated part of the moon gradually increased. The full moon (Wang) appeared at the 15th and 16th of the lunar calendar. The earth was located between the sun and the moon. The side of the moon facing the earth would be illuminated. The round moon could be seen all night. In the lunar phase change chart, it was the phase where the moon was the most illuminated. Fortunately, after the full moon, the illuminated part of the moon gradually decreased. The last quarter of the moon appeared around the 22nd of the lunar calendar. The left half of the moon was illuminated from the northern hemisphere, almost in the shape of a semicircle. The waning moon appeared at the end of the lunar calendar. The protruding part of the moon faced east, like the letter "C." It was the transition from the last quarter of the moon to the new moon. It was close to the beginning of the next cycle in the lunar phase change map. The novel New Moon is equally exciting. Everyone is welcome to click and read it!

Moon phase change sequence chart
The order of the changes in the moon's phase was: New Moon (also known as New Moon, the first day of the lunar calendar. At this time, the moon could not be seen on Earth) → Emei Moon → First Quarter Moon (on the seventh and eighth day of the lunar calendar, the moon's phase was bright on the west side, facing west, in a semicircle) → Convex Moon (including the gradually full moon) → Full Moon (also known as Wang, the fifteenth and sixteenth days of the lunar calendar, the entire moon could be seen) → Convex Moon (gradually losing the full moon) → Last Quarter Moon (on the twenty-second and twenty-third days of the lunar calendar, the moon facing east) → Waning Moon → New Moon (the first day of the lunar calendar). At the same time, due to the different latitudes of the Earth, the moon phase seen in the northern and southern hemisphere was reversed. The novel New Moon is equally exciting.
