What does the new moon mean?

When the moon orbits between the sun and the earth and the dark hemisphere of the moon faces the earth, it is called the new moon, which is the first day of the lunar month. We can't see the moon at this time, so it's called the new moon. The day of the new moon is usually called the "new moon".

Shuoyue appeared in "Poem Xiaoya at the Turn of October": "At the turn of October, Shuoyue is full of food and ugliness." Zheng Xuan wrote: "October in a week is also August in summer. In August, the sun and the moon meet. " "Book of Rites Jade Algae": "Less prison in a month, five years and four years." "Shuori doesn't mean auspicious day" in Jing Yi Wenshutong Shuo Shang introduced by Wang Qing: "The beginning of January means Shuori or Shuoyue."
