Is the full moon according to the lunar calendar or the solar calendar?

At the full moon, it can also be based on the solar calendar or the lunar calendar, depending on personal preferences, but vaccination is calculated according to the solar calendar.

In astronomical phenomena, the moon turns from small to round, which is the full moon, usually on 15 or 16 of each lunar month, but the month of 12 in February is worth watching because it is a "perigee climax"; Folk customs such as buying full moon wine a month after the baby is born and getting married for a month in the New Year are all aimed at getting a good omen.

Extended data:

At the full moon, the moon and the sun are on both sides of the earth. If it is just the opposite at this time, there will be an eclipse. The day and night movement of the full moon is almost the same as that of the sun in spring and autumn, winter and summer. The sun rises at dusk, lies in the middle of the south at midnight, and sets at sunrise.

In summer, you can see that most parts of China rise from the southeast and cross the southern night sky at low altitude. In winter, the full moon in the middle of the south is higher in the night sky. The vernal equinox and autumnal equinox rise near due east and set near due west.
