Is there any scientific basis for the Gregorian calendar?

The yellow calendar should have been called the "imperial calendar". It turned out that on the day of the Winter Solstice every year, the emperor presided over a ceremony at the Wumen Gate to announce the calendar for the coming year, hence the name "Imperial Calendar".

Almanac is an ancient "calendar book" in China, which records dates and solar terms and guides people to arrange agricultural production and life in different solar terms. It has its rationality and authenticity, which cannot be ignored or denied. Some people use the Gregorian calendar as reference information for travel, marriage and market opening, which can stabilize their mood and increase their confidence to some extent.

But we can't indulge in it and become slaves of the yellow calendar; It is not advisable to trust the Gregorian calendar too much, or even regard it as a guide to life.
