Can I get a permit? Marriage is forbidden in the yellow calendar on the wedding day.

If you believe this, you will have it, but if you don't believe it, you won't have it. If both families have relevant beliefs in this respect, it doesn't hurt to follow the calendar.

This is also a peace of mind! There is no evidence that marriage is unhappy if you don't follow the zodiac, don't you think? I hope you can adopt it!
