Wedding planning checklist: a 12-month timeline

In short: start with the three decisions everything else depends on, which are budget, guest count and venue, and make them nine to twelve months ahead. Book the vendors who can only do one wedding a day next, put your wedding website live when your save the dates go out, and keep the last two weeks free of new decisions. A year sounds long; a wedding fills it easily.

Every wedding is different, but the order of planning is remarkably similar. The trap is not that any single task is hard; it is that they arrive all at once when you start too late, and that early decisions quietly depend on each other. A checklist keeps the order straight, so you decide the big things while there is still choice, and the small things when they are actually relevant.

12 to 9 months ahead: the big three

• Set the budget. Agree what you can and want to spend, and who contributes. Every later decision leans on this number; see our wedding budget breakdown for how couples typically divide it.
• Draft the guest list. A rough count is enough at this stage: it decides which venues fit and drives most of the costs. Decide early how you handle day guests, evening guests and children.
• Choose the date and the venue. Popular venues are booked a year or more ahead for Saturdays in high season. Visit two or three, ask what is and is not included, and only sign when the quote is complete.
• Arrange the legal part. Rules differ per country and municipality: notice periods, witnesses, documents. Look up what applies where you marry and put the deadlines in your calendar now.

9 to 6 months ahead: the one-a-day vendors

Photographers, bands, DJs and caterers can only serve one wedding per day. They fill up in the same order the venues do, so book them right after the venue.

• Book photographer and videographer. Choose on style first, budget second; you look at these photos for decades.
• Book music and catering. Get quotes in writing, including travel, overtime and setup costs, which are the classic surprises.
• Send save the dates. Eight to twelve months ahead, and earlier for a destination wedding. Put your wedding website live at the same time, even if it only holds the date and the venue for now.
• Start on the outfits. Made-to-measure needs months, and alterations come on top.

6 to 3 months ahead: shape the day

• Plan the ceremony. Who officiates, who speaks, what music plays. Decide what is legal requirement and what is your own ritual.
• Order the invitations and finish the website. Invitations go out around three months ahead, with the full program, dress code and an RSVP deadline. Let guests reply through the RSVP form on your wedding website, so answers and dietary needs land in one list instead of your inbox.
• Order the rings. Standard collections take weeks to deliver; custom work takes months. Engraving adds more.
• Ask the people you need. Witnesses where required, a master of ceremonies, speakers. Give each of them one page with what you expect.
• Book the extras. Florist, cake, transport, hair and make-up trial.

3 months to 3 weeks ahead: from plans to numbers

• Chase the RSVPs. Set the deadline four to six weeks before the day, and at least two weeks before the venue and caterer need final numbers.
• Make the seating plan. Start after the RSVP deadline, not before; every change before it is double work.
• Write the schedule for the day. Minute by minute, from getting ready to the last dance, with a name responsible for every step. Share it with vendors and the master of ceremonies.
• Plan the guest photos. Decide how you collect the photos your guests take, for instance with a QR code and a live slideshow, and add the printed cards to your order. The same QR trick works for the online guestbook, where guests leave messages and voice notes.
• Confirm every vendor in writing. Times, addresses, contact person on the day.

The final two weeks: no new decisions

• Final fitting and final numbers. Pass the definitive guest count to venue and caterer.
• Hand over the day. Walk the master of ceremonies through the schedule; from now on, questions go to them, not to you.
• Pack a day box. Rings, vows, chargers, painkillers, the printed schedule.
• Protect the buffer. Anything new that comes up now goes on the "after the wedding" list, unless it is truly urgent.

Planning in less than a year?

The same order works on a shorter runway; you simply compress the front. With six months, do the big three in the first month and the one-a-day vendors immediately after. With three months, flexibility is your friend: a weekday or an off-season date opens up venues and vendors that are long gone for Saturdays. Cut decisions, not care: fewer options considered per choice, not more corners cut on the day.

How it works in trwn

This entire checklist lives in trwn as a task list with deadlines on a timeline toward your wedding date, so the right tasks surface at the right moment instead of all at once. The guest list, RSVPs, budget, vendors and the schedule for the day are connected: an RSVP updates your numbers, a quote updates your budget, and the schedule exports as a PDF for your vendors.

Couples get all of it, including the wedding website with RSVP, for one one-time price; see trwn for couples. Wedding planners run every wedding from one dashboard and share exactly this checklist with their couples; see trwn for wedding planners.

Frequently asked questions

When should you start planning a wedding?

Nine to twelve months ahead is comfortable for a full wedding: it is enough time to choose a venue while there is still choice, and to book the vendors who can only do one wedding a day. Start with the budget, the rough guest count and the venue, because every other decision depends on those three.

What should you book first for a wedding?

The venue, immediately after you know your budget and rough guest count. After the venue, book the vendors who can only serve one wedding per day: photographer, band or DJ, and caterer. Everything else, from flowers to transport, has more supply and can wait until three to six months ahead.

When do save the dates and invitations go out?

Save the dates go out eight to twelve months ahead, earlier for a destination wedding. The invitations follow around three months ahead, with the full program, the dress code and an RSVP deadline of four to six weeks before the day, so the venue and caterer get their final numbers in time.

Can you plan a wedding in six months?

Yes, if you compress the start: settle budget, guest count and venue in the first month, and book the one-a-day vendors straight after. Flexibility on the date helps most, because a weekday or off-season wedding opens venues and vendors that are fully booked for Saturdays. The rest of the checklist keeps the same order, just closer together.
