Congrats...  Love the date, you'll never forget!  
I've been married 3 years, got engaged a 9 months before that and to this day I can't tell you which day or month it was.  Though I can tell you how I proposed!
Andy has some good advice, write down everything about the event.  You'll never know when that info comes in handy!
