Is the Gregorian calendar still accurate now?

This is just a personal opinion! Anyway, my dad always turns over the yellow calendar before playing cards, and there will be a sign on it showing which zodiac he played that day! What direction! In other words, on that day, what is unlucky and what is not smooth is really accurate most of the time. If the seat is wrong, he will lose. Ha ha!

I think the Gregorian calendar is a natural law discovered by the ancients through many daily experiences! You have to look at all the wedding calendars!
