Grade one geography and moon phase knowledge points
The moon phase referred to the changes in the moon's phase. The moon shone by reflecting sunlight. Its relative position to the sun was different (the difference in the ecliptic), so it would appear in various shapes. New Moon (the first day of the lunar calendar): The difference between the ecliptic of the sun and the moon is 0°. At this time, the moon is located between the Earth and the Sun, facing the Earth with the dark side, and appears almost at the same time as the Sun. It cannot be seen from the ground. First Quarter Moon (the seventh and eighth day of the lunar calendar): The moon continues to rotate forward. The difference between the ecliptic of the sun and the moon is 90°. When the sun sets, the moon is already above the head. At midnight, the moon sets. At this time, half of the moon illuminated by the sun can be seen. Full Moon (15th and 16th of the lunar calendar): The moon turns to the other side of the earth, and the difference in the ecliptic is 180°. At this moment, the Earth was in the middle of the sun and the moon. The half of the moon that was illuminated by the sun was facing the Earth. At this moment, they could see the full moon. Last quarter moon (Lunar 23): After the full moon, the time when the moon rises is slower by the day, and the bright part of the moon is also smaller by the day. On the 23rd day of the lunar calendar, the ecliptic is 270°, and the full moon is half lost. At this time, the half moon only appears in the eastern half of the sky in the second half of the night.

How to adjust the moon phase on the moon phase watch
To adjust the moon phase function of the moon phase watch, you can follow the following steps: 1. Check the instruction manual or watch online educational videos: The watch's accessory instruction manual usually has teaching content on adjusting the moon phase function, and some brands will also publish educational videos on the Internet. Different brands had different designs, so looking at this information first would help to understand the precautions for adjusting the moon phase function. For example, some watches had time adjustment restrictions. 2. [The reference standard for determining the current moon phase: After mastering the adjustment method, you need to specify the position of the moon during the adjustment.] You can get accurate moon phase information by searching for related tools online (such as time and date). During the adjustment, the new moon could be used as a reference, and the position of the new moon hidden by the two moons on the moon phase plate could be used as the starting point. Then, according to the lunar calendar, it was judged how many days had passed since the last new moon, so as to adjust the correct moon phase. It could also be used as a reference. First, the full moon pattern was placed in the center of the moon phase window, and then adjusted according to the length of time from the last full moon. This could reduce the error. 3. Understand the accuracy of the moon phase function of the watch: The basic moon phase display system uses a 59-tooth gear, and the moon phase period is 29.5 days. However, the actual moon advancement period is not exactly 29.5 days, so the moon phase watch with a 59-tooth wheel will accumulate an error of one day every three months. Therefore, if the watch had this basic moon-phase function, it could be adjusted every three months to ensure the accuracy of the moon phase. In addition, when adjusting the moon phase, you need to pay attention to avoid the time that is not suitable for the fast adjustment device. For most watches, the hour hand should avoid the range of 8 to 4 clockwise.(Because the gears of the quick dial button are tightly fitted from 8:00 pm to 4:00 am every day, the use of the quick dial button will easily cause the mechanical parts to malfunction.) Some special watches (such as Blancpain's moon phase watch) cannot use the moon phase quick dial button at 12:00 noon. In this case, the hour hand can be set back to 8:00 or after 4:00, and then use the quick dial button to adjust the date or moon phase, and then adjust the time.

How to use the moon phase function of the moon phase watch
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!
How to adjust the moon phase of the Blancpain Moon Phase Watch
The steps to adjust the moon phase of the Blancpain Moon Phase Watch are as follows: If it was a full calendar moon phase watch and it was a pointer type moon phase, the pointer must first be aimed at the middle of the full moon. The buttons to adjust the moon phase were mostly on the side of the case. Blancpain's full calendar moon phase watch was adjusted on the patent hidden adjustment button behind the ear. Generally, the date, week, and month were adjusted first, and finally the moon phase was adjusted. However, which button corresponded to the moon phase and which button corresponded to the date and month depended on the specific watch model. You needed to refer to the specific watch manual. Take March 14th, 2017 (the 17th day of the lunar calendar) as an example. There are two days between the 15th day and the 15th day. At this time, you have to pay attention to the number of days ahead, and you have to adjust the calendar to the day before today (if today is the 5th day, then adjust it to the 4th day), and then press the adjust moon phase button according to the calculated number of days (in this case, it is 2 days, press twice). If it was a Blancpain 5054 moon phase watch, its B button was responsible for the moon phase function. Generally, it was best to adjust it after the 15th day of the lunar calendar. Pressing it once would move the moon back by one day. Check the full moon date of the previous month (according to the lunar calendar) and calculate the date to today (the date on the watch is the solar calendar). For example, today is July 15th, the last full moon was July 2nd, and today is 13 days. Press the adjustment button on the outside of the case (watches with moon phase function all have an embedded adjustment button, different brands have different positions), press the moon phase to rotate one day until the moon is in the middle of the moon phase plate, and then press this adjustment button 12 times.

How do you look at the moon phase of the moon phase watch?
Moon phase watches usually set a crescent-shaped window at twelve or six o'clock on the dial to show the changes in the moon phase. To understand the moon phase of the moon phase watch, one must first understand the changes in the moon phase. The first day of the month is the new moon, and the moon rises and sets with the sun. The third day of the month comes out. The first quarter of the eighth day appears in the middle of the night. The fifteenth day of the month is full. Every 24 hours of operation, the movement drives a moon phase disk. The common moon phase disk uses 50 teeth and displays the changes of the moon phase according to the 29.5-day cycle. When the outer edge of the moon was close to the shape of the letter C, it was the moon before the 15th day of the lunar calendar; when the outer edge of the moon was close to the shape of the letter C, it was the moon after the 15th day of the lunar calendar. In addition, in some lunar phase tables, if the full moon is regarded as a circle, no matter how the moon phase changes, the line connecting the upper and lower apices is the diameter of the circle (except for the irregular moon phase during an eclipse).

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!
