The 12-month wedding planning checklist

Most couples get engaged 13 to 14 months before their wedding date, which sounds like plenty of time until you account for how early the calendar fills up. Popular photographers book 12 to 18 months out. Venues in competitive markets fill 12 to 24 months in advance. Dress orders take 4 to 6 months just for production, before alterations. The checklist below covers every major milestone from month 12 through the final week, organized so the sequence makes sense.

What should you do first when you get engaged?

Set the budget and agree on a rough guest count. These two numbers determine which venues are viable, how much catering costs, and whether your dream photographer is financially realistic. Everything else depends on them. Before you research a single vendor, spend an hour establishing both numbers with your partner.

Notes on timing: if you're starting with less than 12 months, prioritize in this order: venue (locks your date), photographer (fills fast), and dress (4 to 6 month production lead time). Everything else can compress to 3 to 6 months.

What are the most important bookings at 10 to 12 months out?

Venue and photographer. The venue booking locks your date, and that date is the input every other vendor needs before they can confirm availability. Photographers in major cities fill 12 to 18 months out; mid-market photographers typically fill 8 to 12 months. Book both as soon as your budget and guest count are settled, and treat everything else as secondary until both are confirmed.

At this stage, also contact an officiant if you have a specific person in mind. Officiants don't fill as fast as photographers, but if you're working with a clergy member or someone from a specific religious community, earlier is better. Civil officiants are generally available with 6 to 8 months notice.

What happens at 6 to 9 months out?

Dress and save-the-dates are the two most time-sensitive tasks in this window. Wedding dress orders typically take 4 to 6 months just for production, before alterations. Many bridal boutiques schedule two to three fitting appointments over 6 to 8 weeks. Order by month 8 at the latest; month 9 if you're in a city with good boutique availability and a simpler style.

Save-the-dates go out 6 to 8 months before the wedding for a local event, 8 to 10 months for destination. They don't need to be elaborate. A simple card or digital notice with the date and location gives guests enough lead time to block their calendars.

Also in this window: florist consultation and booking (florists with a specific style fill up faster than you'd expect), DJ or band (good DJs book 8 to 12 months out in competitive markets), and engagement photos if you want them for the save-the-dates or wedding website.

What's on the list at 3 to 5 months out?

Invitations go out 8 to 12 weeks before the wedding, so if your wedding is in month 0, invitations ship at month 2 to 3. Order them by month 4 so you have time for proofing and printing. Include the RSVP deadline on the invitation itself: 3 to 4 weeks before the wedding gives you enough time to finalize the headcount for the caterer.

This window is also when you finalize wedding party attire. Bridesmaid dresses ordered from a formal retailer can take 2 to 3 months to arrive. Groomswear rentals are usually available with 4 to 6 weeks notice, but 3 months gives you more flexibility for sizing and alterations.

Get your wedding website up at this stage if you haven't already. It's the right place to put accommodation suggestions, directions, FAQ answers, and the registry link.

What do you finalize in the last 2 months?

RSVP follow-up is almost always necessary. A reliable approach is to send a personal message (not a mass email) to anyone who hasn't responded two weeks past the deadline. Most people who haven't RSVPed have simply forgotten.

Once RSVPs are finalized, the seating chart can be done. Allow several hours for this, especially if you have family dynamics to navigate. A spreadsheet approach (one row per guest, assigned table number) is easier to update than a drag-and-drop tool when RSVPs come in late.

Confirm every vendor in writing with a follow-up email that lists: confirmed date, time, location, and payment balance due. Request confirmation back. This is also when you arrange transportation for guests staying at hotels distant from the venue.

What does the final week look like?

The final week is for confirmations, not decisions. Every major decision should already be made. Reconfirm each vendor with their specific arrival time, setup location, and point of contact. Pay any remaining balances. Prepare labeled cash envelopes for gratuities so there's nothing to handle on the wedding day itself.

Hand off the day-of logistics document to your coordinator or a trusted point person. This document should include: vendor arrival times, a contact number for each vendor, the ceremony and reception timeline, and instructions for any venue-specific logistics (where vendors load in, where family gathers for portraits, etc.).

What if you have less than 12 months to plan?

The sequence stays the same; the timeline compresses. Prioritize: venue first (locks the date), then photographer (the category with the tightest availability window), then dress (requires the most lead time for production). With 6 months to work with, book those three within the first 4 to 6 weeks.

How do you stay on top of everything over 12 months?

A single shared document, updated consistently, is the most reliable system. The problem with planning apps is that they give you structure but not flexibility, and most of them put the content behind a paywall or subscription. A well-built spreadsheet covers the same ground at a fraction of the cost and is easier to customize for your specific situation.

The Sera Planner covers tasks, budget, guest list, vendor contacts, seating, and a dashboard in a single Google Sheet. Both partners can access and edit it simultaneously from any device.

Frequently asked questions

What's the first thing to do when planning a wedding?

Set the budget and agree on a rough guest count. These two numbers determine everything else: which venues are realistic, how much catering costs, and which vendors fit your budget. Don't book anything before you have both.

How far in advance should you book a wedding photographer?

In most US markets, 10 to 12 months is standard. Top photographers in major cities like New York, Los Angeles, and Chicago fill up 12 to 18 months out. Book immediately after confirming the venue.

When should you send wedding invitations?

Formal invitations go out 8 to 12 weeks before the wedding, with RSVPs requested 3 to 4 weeks before the date. Save-the-dates go out earlier: 6 to 8 months for a local wedding, 8 to 10 months for destination.

What if I only have 6 months to plan a wedding?

Focus on the four things that fill up fastest: venue, caterer (if not included), photographer, and dress. These need to be booked or ordered immediately. Florists, DJs, hair, and makeup can typically be booked 3 to 4 months out.

How do you stay organized through 12 months of wedding planning?

A single shared document, updated every time you make a decision or booking, is the most reliable method. Most couples use a spreadsheet with a task list, budget tracker, and guest list in connected tabs. Starting with a pre-built template saves several hours of setup.
