More than six months of planning time.  First off, calm down.  Let your boss talk it out.
Here's my suggestion - you will have plenty of time to bring a temp up to speed to cover your time off.
I would even offer if possible to check email at least once a day to respond to an emergencies maybe after the first three days so you feel like you get a real wedding and vacation.
I went through something similar, my boss and I were getting married within a month of each other.  I felt like I was planning two wedding.  Hers was mostly travel arrangements and destination wedding planning.  For mine my future hubby was great Jan 1 we sat down and marked deadlines on the calendar for items.  Cater week X, Flowers week y etc.
Kept me sane.
PS I wouldn't move your date unless you want to go to July 21st?
PPS BEST WISHES!
