How to use the moon phase function of the moon phase watchThe 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.

Moon Phase MapThe moon phase diagram was related to the moon phase. The phases of the moon referred to the different positions of the earth, the moon, and the sun. The parts of the moon that were illuminated on Earth would periodically change and appear in various shapes. The changes of the moon were generally divided into stages such as the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, and waning moon.
The moon itself did not emit light. It mainly shone by reflecting sunlight. When the moon passes between the earth and the sun (the first day of the lunar calendar), the back of the moon is illuminated by the sun and cannot be seen on earth. This moon phase is called "New Moon"(New Moon). On this day, the moon and the sun rise and set almost at the same time. Soon after the sun sets, the crescent moon can be seen in the western sky.(The protruding part of the moon faces west, forming an inverted C shape); The first quarter moon appears around the seventh day of the lunar calendar.(In the northern hemisphere, the right half of the moon is illuminated, forming a semicircle); At the 15th and 16th of the lunar calendar, the earth is between the sun and the moon, and the side of the moon facing the earth is illuminated, which is the "Wang"(full moon); Around the 22nd of the lunar calendar, the last quarter moon appears (in the northern hemisphere, the left half is illuminated); At the end of the lunar calendar, it is the waning moon (the protruding part of the moon faces east, like the letter "C"), and then the moon phase returns from the waning moon to the new moon, starting a new cycle. The lunar phase changes every 29.5306 days. The moon phase map might be a graphic representation of these different moon phases and related information, used to show astronomical research or popular science purposes such as the law of moon phase changes.

The phase of the moon in a monthThe changes of the moon in a month were as follows:
1. New Moon (New Moon): Appears on the first day of the lunar calendar. The moon is between the earth and the sun, rising and setting with the sun. When observed from the back of the moon, the moon seems to be completely dark.
2. ** Emei Moon **: Appears on the second to seventh day of the lunar calendar. It is shaped like a sickle and can only be seen after sunset.
3. ** First Quarter Moon **: Appears on the 7th and 8th day of the lunar calendar. The sun, earth, and moon form a right angle. It rises at noon and appears in the south sky at dusk. It can be seen in the first half of the night.
4. ** Convex Moon **: Around the 11th or 12th day of the lunar calendar, it will continue to light up and face west. It will set in the west before dawn and can be seen most of the night.
5. ** Full Moon (Wang)**: Appears around the 15th day of the lunar calendar. The sun rises from the east after sunset. Midnight is in the sky due south. It sets in the west in the morning and can be seen all night. At this time, when observing the moon from the direction of the moon, the moon is almost completely bright.
6. Last quarter moon: Appears on the twenty-third day of the lunar calendar. The sun, the earth, and the moon form a right angle. Midnight rises from the east. The sunrise hangs high in the southern sky. At noon, it sets in the west. It can be seen in the second half of the night.
7. Waning Moon: Appears at the end of the 24th lunar month, also known as the second half of the crescent moon. The upper crescent moon appears in the evening and the first half of the night in the western sky, and the lower crescent moon appears in the eastern sky at dawn and the second half of the night.
The cycle of the moon's phase change was 29.5306 days, which was 12:44:3 on the 29th. This cycle was called the lunar month.

Watch the moon phaseThe moon phase watch was a special watch that was mainly used to record the movement of the moon, day and night. There were 59 teeth on the moon phase disk, and one tooth was moved every day. As a result, each set of moon phase patterns had a cycle of 29.5 days, which symbolized the cycle of the moon phase. There would be a " half-moon " window on the dial, and the moon phase plate was usually dark blue with two sets of symmetrical patterns on it, including two round moons with a starry sky in the middle. The moon phase plate and the dial window worked together. As the moon phase plate moved slowly, the first quarter moon, full moon, and last quarter moon would appear in turn.
There were a variety of moon phase watches available at different price points. For example, the 1,000 yuan price range included the Berenceli Collection series of smiling moon phase watches from the Swiss Medo watch. The moon phase plate was uniquely designed, resembling a crescent moon, which could show the dynamic changes of the moon phase well. At the price of 10,000 yuan, there was the Emillon Lemon series moon phase watch, which had a circular moon phase display plate at 6 o'clock, and the dark blue night sky perfectly blended into the plate. At the price of 20,000 yuan, there was the Longines classic replica series military flag watch. In addition, there were more expensive moon phase watches, such as the Blancpain classic series 6654 - 1127 - 55B, which had a highly recognizable face moon phase at 6 o'clock; the Jaeger-LeCoultre Full Calendar Moon Phase Watch, which perfectly integrated the moon phase display at 6 o'clock with the overall layout; Glashütte's original eccentric moon phase watch, with a blue moon phase display window at 2 o'clock. Different brands and styles of moon phase watches have differences in appearance, movement, functions, etc., and can be selected according to their own needs and preferences.

Moon Phase DiagramThe phases of the moon were divided into the new moon, the crescent moon, the first quarter moon, the gradually full moon, the full moon, the gradually waning moon, the last quarter moon, and the waning moon. At the new moon, the moon and the sun were on the same side of the earth. From Earth, the moon was dark, and the moon's phase was almost invisible (because it rose and set at the same time as the sun). The crescent moon was in the shape of a scythe. It could be seen from the second to the seventh day of the lunar month and appeared in the western sky a while after sunset. The first quarter moon was on the seventh day of the lunar month. The sun, earth, and moon were at right angles. It appeared at noon and at dusk in the southern sky. It could be seen in the upper half of the night. The crescent moon was about eleven or twelve, bright facing west, setting in the west before dawn, visible most of the night. During the full moon, the moon and the sun were on opposite sides of the earth. At this time, the moon was almost completely bright. After the sun set, it rose from the east. Midnight was in the south sky, and in the morning, it set in the west, so it could be seen all night. After the full moon, the brightness of the waning gibbous moon gradually decreased. The last quarter of the moon is at twenty-two or twenty-three, and the sun, earth, and moon are once again at right angles. Midnight rises from the east, sunrise hangs high in the southern sky, noon sets in the west, and the second half of the night can be seen. The waning moon was at the end of the twenty-fourth month, also known as the crescent moon in the second half of the month. The difference between the crescent moon and the crescent moon was that the crescent moon appeared in the western sky in the evening and the first half of the night, while the crescent moon appeared in the eastern sky at dawn and the second half of the night. After that, the new moon would return to the new moon, completing a lunar phase cycle of 29.5306 days.

The interpretation of the moon phaseThe moon phase can be judged according to the following points:
First of all, he had to understand the root cause of the moon's phase. The moon itself was neither luminous nor transparent, but it could reflect sunlight. As the relative positions of the sun, the earth, and the moon constantly changed, it produced different shapes, which were the phases of the moon.
1. ** New Moon (New Moon)**
- It happened on the first day of the lunar calendar. At this time, the moon was between the earth and the sun, and the moon could not be seen at night on earth.
2. ** New crescent moon **
- It appeared on the third and fourth day of the lunar calendar. It was in the shape of a sickle and appeared in the evening sky in the west.
3. ** The first crescent moon **
- It happened on the seventh and eighth day of the lunar calendar. It was semi-circular, with the moon rising at noon and setting in the middle of the night. The moon was facing west and was located in the western half of the sky (the concave side was facing east), appearing in the first half of the night.
4. ** New Crescent **
- On the 11th and 12th of the lunar calendar, the bright parts of the moon increased day by day.
5. ** Full Moon (Hope)**
- It happened on the fifteenth day of the lunar calendar. The moon rotated to the opposite side of the earth and the sun (the earth was between the moon and the sun). The hemisphere of the moon illuminated by the sun was facing the earth. What one could see was a full moon, and its relationship with the sun was rising and falling.
6. ** Remnant Moon **
- On the 17th and 18th of the lunar calendar, the moon was facing east, and the half of the sphere facing west was decreasing day by day.
7. ** Last quarter moon **
- It happened on the 22nd and 23rd of the lunar calendar. It was semi-circular, with the moon facing east (the concave side facing west). It rose in the middle of the night and set at noon. It appeared in the second half of the night in the eastern half of the sky.
8. ** Waning crescent moon **
- The 27th and 28th of the lunar calendar were the phases of the moon. The waning moon hung in the eastern sky before dawn, and then the new moon would arrive.
He could also use the formula "Up, Up, West, Down, Down, East" to help him remember. The first quarter moon appeared in the first half of the lunar month in the first half of the night. The moon faced west and was located in the western half of the sky. The last quarter moon appeared in the second half of the lunar month in the second half of the night. The moon faced east and was located in the eastern half of the sky.

October 2024 Moon PhaseOctober 9, 2024 was the first quarter moon, but the reference did not provide the complete moon phase for the entire month of October 2024, so it was impossible to accurately answer the moon phase for the entire month of October.

Moon phase and dateThe phases of the moon were different from the positions of the Earth, the Moon, and the Sun. The parts of the moon that were illuminated on Earth changed periodically and appeared in various shapes. The phases of the moon were generally divided into the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, and waning moon. The corresponding dates were as follows:
- The first day of the lunar calendar was the new moon. At this time, the moon moved between the earth and the sun. The back of the moon was illuminated by the sun, and the moon could not be seen on earth. The moon and the sun rose and set almost at the same time.
- A crescent moon appeared after the new moon. 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 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 and formed a semicircle.
- The fifteenth and sixteenth days of the lunar calendar were the full moons. The Earth was located between the Sun and the Moon. The side of the Moon facing the Earth would be illuminated, and the full moon could be seen all night.
- The last quarter of the moon was around the 22nd of the lunar calendar. 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.
- The end of the lunar month was the "waning moon". It appeared in the eastern sky at dawn, and the protruding part of the moon was facing 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 moon phase map was a special term in astronomy. It was a visual representation of the moon's appearance at different stages. Through the moon phase map, one could directly see the changes of the moon phase corresponding to different days.
