Making 18 months work
Pick one and build the plan around it. There are blank ideas pages in the planner for screenshots and sketches.
Book the scarce things first
Venue, photographer and, for big weddings, the caterer. Everything else can wait.
Save monthly
Divide the budget by the months left and put a savings goal on each monthly page.
Engagement photos
Use them for save-the-dates and to get to know your photographer.
Off-peak date
With this much notice, a Friday or winter date can cut venue costs noticeably.
Destination check
Abroad? Look up the legal paperwork for marrying there now — it can take months.

- Check the legal requirements for your marriage licence early.
