Does anyone know the yellow calendar?

You see, in the yellow calendar, any day suitable for childbirth is appropriate. When to have a baby is not for you to decide.

According to your idea, I remember which days were written on the Gregorian calendar to avoid doctors and kill people. Choose any day that is suitable for going out to have a knife. To put it bluntly, it is not the last step to have a good baby, but a natural birth is better.
