The formation of solar eclipse needs to meet two conditions: first, solar eclipse always occurs on the first day of the lunar calendar. Not all eclipses will happen on the first day of the lunar calendar, because the orbit of the moon (ecliptic) and the orbit of the sun (ecliptic) are not on the same plane. There is an included angle of 59 between the ecliptic plane and the ecliptic plane. On the first day, if both the sun and the moon move near the intersection of the ecliptic and the ecliptic, and the sun and the intersection form a certain angle (eclipse limit), an eclipse will occur, which is the second condition to be met. "
It can be seen that the formation of the solar eclipse must be in the first day, that is, the combination of the sun and the moon in astrology; Just like the eclipse will basically be on the fifteenth day, that is, the astrological sun and moon will hedge. But not every time the sun and the moon meet or hedge, it will constitute an eclipse.
Solar eclipse, special new moon
The conjunction of the sun and the moon is the beginning of a moon cycle in astrology, so it often has the symbolic meaning of "new beginning, new starting point". It is generally accepted by western astrologers that the first day (the conjunction of the sun and the moon) is suitable for launching a new stage plan and starting to change in order to meet new things.
Therefore, every day when the sun meets the moon (new moon) is a sign of a new starting point, symbolizing that change is about to begin. Then, the special combination of the sun, the moon and the eclipse has given birth to the meaning of a new beginning.
Liang Shang is the most solemn day to build a house. The carpenter's senior engineer hoisted the crossbeam, hung red cloth length, green cloth length, grain bag, nails, pulp cutting, wooden hammer and red light at the same time, then set off firecrackers and threw steamed bread. Carpenters praise Shangliang's poem, which means that Feng Shui will come back to life, live and work in peace and contentment, children and grandchildren will flourish, financial resources will be extensive, officials will hold high positions, and family status will be noble.
Shangliang is also a new beginning, and the meeting of the sun and the moon is of great significance.
Good luck.
