The formation of solar eclipse The so-called "eclipse" refers to the astronomical scene in which one celestial body is completely or partially covered by another celestial body or its shadow. There are three kinds of eclipses: total solar eclipse, partial solar eclipse and annular solar eclipse. The principle of solar eclipse is that some parts of the earth are covered by the moon shadow.

the solar eclipse must occur on the new moon, that is, the first day of the lunar calendar. This is because only on that day will the moon appear on the line between the sun and the earth, so that it is possible for the moon to block the sun and form an eclipse. Similarly, the eclipse must appear on the lookout day, that is, the fifteenth day of the lunar calendar.
