What does it mean to have a day? How to explain it?

1, the opening of the day means a smooth start and Pepsi is feasible.

2. Building a day: refers to the initial stage when things are not completed. Suitable for laying foundation, breaking ground, opening axe, turning on lights and installing seats, but not others. Success: It means that everything can be done and everything can be handled. These twelve duty days are: "establishment, division, full day, weekdays, fixed days, observance, completion, closing, breaking, dangerous days, opening and closing" in the yellow calendar, which are used to judge good or bad luck. Will "build, divide, fill, level, decide, hold, break, be in danger, succeed, merge and open."

3. China's traditional calendar is based on heavenly stems and earthly branches's arrangement, combination and circulation, which means repetition and reappearance. It is this "recurrence" that makes it meaningful to choose a date to avoid it. The fundamental basis for the ancients to formulate calendars and determine auspicious days is the sun, the moon and the stars. Among them, the stars are the most critical factor in determining the date, and the Gregorian calendar basically does not consider these, so there is no so-called taboo.
