Which is more accurate, the online almanac or someone to check?

I have seen the Gregorian calendar, which is a little superstitious. Mainly auspicious. There are big and small, big and small, red and white, which have been passed down since ancient times. The effect is very good, and no one has used it yet. Is it an app? I don't know what you want, and I can't give you a suitable answer. I'm just here to finish the task of Baidu, but I believe in the zodiac.
