How to solve the problem of getting married that day? Thank you.

If you can change the time, change it; If you can't do it, let it be. Don't be too superstitious. Now that you have set the time, don't think too much. The rest of your life depends on the way you two get along, not the good days. Many so-called masters' statements are deceptive! Facing metaphysics scientifically, don't cling to wrong beliefs, it will hurt yourself.
