Now you may be thinking, "What on earth made you want to get married on Halloween?" Believe it or not, Halloween is a date that many couples are choosing to perform their nuptials. For us, it was the anniversary of our first date and it is a day that both of us can easily remember. Halloween is popular for pagan weddings because of the New Year/New Life symbolism. It is popular with devotees of goth culture for obvious reasons and nearly everyone else because of its associations with parties and fun.
