I know there's a few of you on here that wrote your own. I wanted to know, how do you know how long your ceremony is/will be? I'm trying to figure out what time I should start my ceremony so I can have it on my invitations. I can have it at either 4 or 4:30. If we start at 4:30 (which was my original plan) I'm afraid of going over because it will go into the cocktail hour and we won't get an time extended. If we start at 4 there is no way our ceremony will be an hour long. HELP!
