What does it mean to avoid praying in the yellow calendar?

Gregorian calendar is a calendar handed down from the reign of the Yellow Emperor, in which the goal of pursuing good fortune and avoiding evil is the ancestor's god, so prayer is forbidden, and the same is true. It does not include Buddha, Bodhisattva and Lohan, because the former is only six sentient beings, but the latter transcends reincarnation, so it is not influenced by the former, so you can still make a wish in the temple.
