The Ultimate Wedding Planning Checklist: What to Do and When
Just got engaged? Congratulations — and take a breath, because that mental to-do list already spinning in your head is about to get a lot more manageable. Wedding planning feels overwhelming mostly because no one hands you a clear order of operations. So here it is: an honest, month-by-month guide to what to do and when, from the day you say “yes” to the day you say “I do.” As a Bergen County venue that’s helped countless couples through this, we’ll also flag the one decision that unlocks everything else.
First: The “Big Four” Conversation
Before you book anything or pin a single idea, sit down with your partner (and anyone contributing financially) and align on four things: your overall budget, your rough guest count, your general vision or style, and your ideal timeline. These four decisions drive every other choice you’ll make, so getting on the same page early saves enormous stress later. Resist the urge to jump ahead to flowers and colors before these are settled.
12+ Months Before: Lay the Foundation
This is the most important phase, and it centers on one thing above all: booking your venue. Here’s why the venue comes first — it locks in your date, sets your guest capacity, and anchors your entire aesthetic. Most other vendors can’t even confirm availability until they know your date and location. So in this early window:
Set your budget and finalize your guest-count range. Research and tour venues, then book the one you love. Once your venue and date are secured, book your photographer — the best ones fill up 12 to 18 months out. Start thinking about your overall style and begin a mood board.
Lock these in and everything else falls into place around them.
9–12 Months Before: Book Your Key Vendors
With your venue and date set, now you build your team. Book your caterer (or, if your venue handles catering in-house like we do, you’re already ahead here). Secure your entertainment — band or DJ — and your florist. If you’re wearing a gown, order it now, since dresses often take many months to arrive and are one of the biggest timeline constraints. This is also a great time to book your officiant and start your wedding website. We have amazing preferred vendors and can help walk you through each step to make the process as easy as possible.
6–9 Months Before: Fill in the Details
The big pieces are in place, so now you refine. Choose and order your invitations and save-the-dates. Plan your menu and schedule a tasting. Book any remaining vendors — hair and makeup, transportation, rentals. Reserve room blocks for out-of-town guests. Begin planning your ceremony details and think through your timeline for the day.
3–6 Months Before: Bring It Together
Now the vision becomes real. Send your invitations 8 to 10 weeks before the wedding, and set your RSVP deadline for 3 to 4 weeks out so you have time to finalize numbers. Finalize your menu selections, order favors, purchase wedding bands, and write your vows. Have your dress fittings. Confirm the details of your timeline with your vendors and venue.
1 Month Before: Confirm Everything
The final stretch is about confirmation, not creation. Give your venue and vendors your final guest count. Confirm arrival times and the day-of timeline with everyone. Create your seating chart once RSVPs are in. Have your final dress fitting, pick up your attire, and put together anything you’re bringing yourself. Then — as much as you can — relax and get excited.
The Week Of: Let Go and Enjoy
You’ve done the work. This week is for delegating, not doing. Hand off final details to your venue coordinator and wedding party, pack for your honeymoon, and give yourself permission to be present. At a venue like ours, where the team handles the day-of execution, this is where all that early planning pays off — you get to simply enjoy your wedding.
Frequently Asked Questions
What is the first thing to do when planning a wedding?
Start with the “Big Four”: set your budget, draft your guest count, define your vision, and set your timeline. Then book your venue first, since it locks in your date and guest capacity and most other vendors depend on it.
How long does it take to plan a wedding?
Most full-size weddings (100+ guests) take 12 to 18 months to plan comfortably. Smaller weddings under 50 guests can come together in 3 to 6 months with more flexibility on date and venue.
What should you book first for a wedding?
Book your venue first, followed by your photographer. These are the most time-sensitive, as popular venues and photographers fill up 12 to 18 months in advance. Your venue also determines your date, which every other vendor needs.
When should wedding invitations be sent?
Mail invitations 8 to 10 weeks before the wedding, with an RSVP deadline 3 to 4 weeks before the date, so you have time to finalize your seating chart and give your venue a final headcount.
