What does the yellow calendar mean to avoid opening the market?

Avoiding opening the market in the yellow calendar refers to avoiding opening the market on some unlucky days when using the yellow calendar (the traditional time calendar in China) for business or economic activities. Because these days, the five elements and eight characters are inconsistent with commercial activities, which will bring losses or adverse effects to businesses.

According to traditional superstition, the Gregorian calendar can calculate the good and bad luck every day, and has strict regulations on matters such as opening the market and getting married. For example, the days when the opening of the market is forbidden in the Yellow Calendar usually include days with many taboos, such as "No Sun in Five Days", "No Sun in Five Blessingg" and "No Sun in Five Tombs". Opening the market these days may cause bad chain reactions, so it should be avoided.

However, with the development of modern science, it is no longer generally regarded as an accurate and reliable superstition, but more of a folk cultural heritage. More merchants pay more attention to their own brand strength, market environment and economic benefits when opening the market. However, for some traditional businessmen or superstitious people, it is still a belief and custom to follow the Gregorian calendar to open the market.
