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 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!
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. The first day of the lunar calendar was the new moon. The moon was located between the earth and the sun. The back of the moon was illuminated by the sun. The moon could not be seen on earth. The moon and the sun rose and set almost at the same time. Soon after the sun set, a 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 first half of the night. From the northern hemisphere, the right half of the moon was illuminated, forming 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. The last quarter of the moon was around the 22nd of the lunar calendar. It could be seen 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 month, it was a waning moon. At dawn, it could be seen in the eastern sky. The protruding part of the moon faced 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. You can draw a picture of the moon's phase changes according to these descriptions or search for the moon's phase changes on the Internet to view it directly. The novel New Moon is equally exciting.

The fundamental reason for the change of the moon's phase was that the relative positions of the three celestial bodies, the sun, the moon, and the earth, were constantly changing regularly. Since the moon itself did not emit light, it mainly relied on reflecting sunlight to shine. When the relative positions of the three were different, from the perspective of an observer on Earth, the part of the moon illuminated by the sun would appear in various shapes, resulting in changes in the moon's phase.

The changes in the moon's phase were caused by the changes in the positions of the three celestial bodies, the sun, the moon, and the earth. The moon itself did not emit light. It mainly relied on reflecting sunlight to shine. Its relative position to the sun was different (the difference in the ecliptic), so it would appear in various shapes. As the moon moved from west to east in the starry sky every day, its shape also changed constantly. This was the change of the moon's phase. For example, when the moon was located between the Earth and the Sun, and the difference in the ecliptic of the sun and moon was 0°, the dark side faced the Earth and appeared almost at the same time as the Sun. This was the New Moon (the first day of the first lunar month). At the 15th and 16th of the lunar calendar, the moon turned to the other side of the earth. The earth was between the sun and the moon, and the half of the moon illuminated by the sun was facing the earth, which was the full moon. The novel New Moon is equally exciting.

He could use the moon phase formula to remember the changes of the moon phase,"up, west, down, east." Its meaning was: the first quarter moon appeared in the first half of the lunar month, facing west, 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, facing east (the concave side facing west), located in the eastern half of the sky. In addition, the moon's phase changes in a lunar month were roughly as follows: from the first day to the fifteenth day, the new moon, the crescent moon, the first quarter moon, the full moon, and the full moon, the "bright side" gradually increased; from the fifteenth day to the thirtieth day, the full moon, the weak moon, the last quarter moon, the waning moon, and the new moon, the "bright side" gradually decreased. It could also be understood like this: on the first day of the first month, the moon and the sun rose and set at the same time; on the first quarter of the first month (the seventh and eighth day of the first month), the moon rose at noon and disappeared at midnight; on the fifteenth and sixteenth month of the first month (the fifteenth and sixteenth month), the moon rose at noon and disappeared at sunrise; on the last quarter of the first month (the twenty-second and twenty-third month), the moon rose at midnight and disappeared at noon.

The changes of the moon were generally divided into new moon (the first day of the lunar calendar), crescent moon (the third and fourth days of the lunar calendar), first quarter moon (the seventh and eighth days of the lunar calendar), full and protruding moon (the eleventh and twelfth days of the lunar calendar), full moon (the fifteenth and sixteenth days of the lunar calendar), waning and protruding moon (the eighteenth and nineteenth days of the lunar calendar), last quarter moon (the twenty-second and twenty-third days of the lunar calendar), and waning moon (the end of the lunar calendar). A cycle was completed from the first to the thirtieth day of the lunar calendar. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
The usage of the moon phase watch is as follows: ** I. Moon Phase Wheel and Moon Phase Cycle Theory ** 1. The moon phase wheel would move one tooth every day and rotate one full circle every two months. The average time of the month was 29.5 days, so the moon phase wheel had 59 teeth. This meant that the changes in the moon's phase were displayed on the dial according to this rhythm. 2. Due to the difference between the exact rotation period of the moon and the moon phase wheel, the error in the moon phase display would reach 24 hours every 33 months. ** 2. Basic operations of moon phase adjustment ** 1. ** Based on the 15th day of the lunar calendar ** - During the adjustment, the full moon on the fifteenth day of the lunar calendar was used as the benchmark, and the moon pattern on the moon phase table was aimed at the middle. For example, if today was the second day of the lunar calendar and the end of the lunar calendar last month was the 29th, the adjustment calculation method was 29 minus 15, plus 2. If the lunar calendar had 30 days, then add 1 more day. This kind of adjustment was usually done by the quick adjustment button on the side of the moon phase watch case, or by rotating the dragon head. 2. ** Quick Dialing Notice ** - In most cases, you can speed dial the moon phase in the second gear, but don't speed dial between 3:00 and 4:00 in the morning.(For some watches, such as Blancpain's moon phase watch, you can't use the moon phase fast dial button at 12 o'clock in the afternoon. The workaround is to turn the hour hand back to 8 o'clock or after 4 o'clock, then use the fast dial button to adjust the date or moon phase, and then adjust the time.) Because the gears are in the engaged state, if you force the fast dial, it will cause internal parts to be damaged. 3. ** Illustrate the adjustment steps ** - For example, today was September 8th, and the last full moon was September 4th (you can find it on the Internet). First, adjust the moon phase to the full moon (this time represents September 4th), and then move the four teeth. This is the moon phase on the 8th. Before the operation, the position of the moon had to be adjusted to the center to confirm that it was the fifteenth day of the lunar calendar. Then, based on the fifteenth day of the lunar calendar, he calculated it day by day. Normally, as long as a normal moon phase watch was corrected, it would take two years and seven months before the error would accumulate to one day. If there was a difference of one day, then only on the 15th day of the lunar calendar would there be an obvious difference between the moon phase chart on the watch and the moon in the real night sky. The rest of the days would basically be impossible to see. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
