Moon, how to distinguish the new moon from the waning moon?

The moon's face is sometimes round, sometimes curved and sometimes semicircular. This is called the moon phase, because the moon can't shine, and only the side illuminated by sunlight has a chance to be seen by us. However, because the moon revolves around the earth, the illuminated side is not always visible, so the moon has changed round after round.

Do different moon phases have different names?

On the first day of each month in the lunar calendar, when the moon moves between the sun and the earth, the moon faces the earth with its dark side and rises and disappears with the sun, so people can't see it. At this time, the moon phase is called new moon or new moon.

After the new moon, the moon gradually moved out of the curve area between the earth and the sun. This is a small part of the moon that we began to see illuminated by sunlight, with clear arc-shaped slices, so the moon phase at this time is called the waning moon.

By the eighth day of the eighth lunar month, the moon has moved to the 90-degree angle east of the sun. At this time, we can see the bright half of the moon in the west. At this time, the moon phase is called Upper Xuan Yue, and Upper Xuan Yue can only be seen in the first half of the night, and disappears on the horizon at midnight.

After arriving in Xuan Yue, the moon became full day by day, which is the so-called convex moon.

On the fifteenth and sixteenth day of the lunar calendar, you can see the whole round surface of the moon. At this time, the moon phase is called full moon or full moon. At dusk, the full moon rises in the east and sets in the west at dawn.

After the full moon, as the position of the sun and the moon approaches, the moon begins to thin again. It went through several stages, including the protruding moon, the lower Xuan Yue and the Emei moon, and finally returned to the position of the new moon.

China used to call the waning moon in the second half of the month a waning moon, so the new moon does not correspond to the waning moon, but the new moon corresponds to the full moon. The moon looks brightest at the full moon, darkest at the new moon, or even completely invisible. The waning moon is suitable for Emei moon, which corresponds to curved eyebrows, but it opens in different directions.

Then how to distinguish the waning moon from the waning moon?

If the moon sets behind the sun, it is Emei, if it sets in front of the sun, or rises in front of the sun in the morning, it is the waning moon. This method is applicable to both the northern hemisphere and the southern hemisphere.

When did the solar eclipse happen?

When the moon is between the earth and the sun, blocking the sun, the light will have an eclipse, so it is only possible to have an eclipse at the new moon around the first day of the lunar calendar.
