Making it to your wedding day takes a lot of planning and a little luck.

When you finally do get to the Big Day, the last thing you want is to bring bad luck upon you and your spouse-to-be. If you're superstitious, get ready -- there are a lot of nuptial rules for you to follow.

Starting with your rings: Legend has it has it that couples will have bad luck in marriage if they shop for wedding rings on a Friday -- especially Friday the 13th. But if Friday is the only time you've got to buy your bling, and you need to reverse the curse, you might consider letting a feline friend use your left wedding shoe as a food dish a week before you tie the knot.

In honor of Friday the 13th, we've rounded up some of the weirdest wedding day superstitions. Click through the slideshow below to learn what to do (and not to do) if you want to have good luck on your Big Day.
