What does "calendar blank" mean?

A day in the Japanese lunar calendar.

In ancient China, it was an unlucky day to have a "red calendar". In the folklore of the Han nationality, the red dog is an "angry god", which will bring bad luck, so the third day of the first lunar month is an unlucky day, so it is not appropriate to go out for a feast; In addition, the word "red" means "extreme poverty", and going out to attack the red dog will bring poverty. If you must go out to pay a New Year call, you can put a bag on your body to relieve the breath.

In Japan, "Lichikou" is the only one of the six obsidians that has not been renamed. Only noon (about 1 1 in the morning to about 1 in the afternoon) is auspicious, and other times are fierce.
