If you believe that consecutive dates are lucky or at least memorable then 12/13/14 may be you last chance to get lucky in this life time. The next time the sequence restarts with 1/2/3 will be 90 years from now. Barring a scientific miracle, you will be well and truly dead. Better get lucky while you're still kicking it.
So if you are going to get married anyway, it looks like you could choose worse than 12-13-14 . At least the hubby won't forget your anniversary!
