Know when to delegate
The best way to keep four weeks worth of wedding planning chaos under control is to hand over some of that control to someone who actually knows how to plan a wedding. Whether it's a professional wedding planner or a relative who's done this a time or two, having a little help during the process doesn't hurt -- especially with 56% of grooms being only "somewhat involved" in the planning process.

"A very big part is delegating and agreeing to give up control," Naylor says. "You simply can't do a wedding of more than 10 people in that time on your own."

While 12% of couples pull in a family member to help with the wedding planning, the 19% of couples who use professional wedding planners may pay an average of $1,683 for the privilege. That may be a bit steep for couples with time to spare, but couples on the clock may want to shell out just for the planner's database of available venues.

"You have to see what you can do and let life surprise you," Naylor says. "There may be powerhouses like Ivanka Trump who can call a wedding planner and say 'I want this all done in a month' and it gets done, but the average person isn't Ivanka Trump."
