Why a Timeline Matters

Events fail because of poor timing, not poor ideas. A great vision executed on a rushed timeline produces stress and mistakes. The same vision with 12 months of organized planning produces a seamless, enjoyable event. This checklist works for weddings, galas, corporate events, and milestone celebrations. Adjust the specifics to your event type, but follow the timeline.

12 Months Out

  • Set the budget (total and by category)
  • Choose a date (or narrow to two or three options)
  • Research and visit venues
  • Book the venue (the first thing to lock down)
  • Begin the guest list
  • If it's a wedding: choose the wedding party

10 to 11 Months Out

  • Book the photographer
  • Book the caterer (or begin conversations if the venue has a preferred caterer)
  • Book entertainment (DJ, band, or musicians)
