Wedding Planning Checklist: What to Do and When
Wedding planning is not one long list of tasks. It is a handful of deadlines that depend on each other, and each one has a point after which your options narrow. This checklist counts backwards from your wedding date and shows what belongs in each window, from twelve months out to the week of the wedding.
Plan backwards from your date: at 12 months book the venue, photographer and videographer and draft the guest list; at 9 months lock catering, music and the dress; at 6 months handle invitations, honeymoon and flowers; at 3 months mail invitations and collect RSVPs; at 1 month run trials and confirm vendors; in the final week give the caterer your headcount and settle payments.
Wedding planning timeline at a glance
| Time before the day | What to do | Why then |
|---|---|---|
| 12 months | Book the venue, shortlist photographer and videographer, draft the guest list | The venue fixes your date and your maximum guest count, and everything else is priced against it. Photographers take one wedding per day, so peak Saturdays go first. |
| 9 months | Choose catering after a tasting, book the band or DJ, order the dress | Bridal gowns have production and alteration lead times measured in months, and in-demand bands lose their peak-season Saturdays earliest. |
| 6 months | Design and print invitations, book the honeymoon, agree the floral plan | Print runs, flights and accommodation all reward booking early rather than well. |
| 3 months | Mail the invitations, collect RSVPs, order the cake, draft the seating chart | Three months comfortably covers the standard 6-8 week mailing window and leaves time to chase non-responders. |
| 1 month | Hair and makeup trial, final confirmation with every vendor | If a trial does not go the way you hoped, there is still time to change course. |
| 1-2 weeks | Give the final headcount, call anyone who has not replied | Most caterers and venues need confirmed numbers 7-14 days before the event. |
| Wedding week | Hand over the final seating chart, settle outstanding balances and tips | Nothing that involves printing or a bank transfer should land on the morning itself. |
What to do at each point before the wedding
12 to 9 months: the bookings that shape everything else
- Venue: the first real decision, because it sets the date, the guest ceiling and roughly half the budget in one go. Until it is signed, booking anything else is guesswork.
- Photographer and videographer: The Knot recommends booking these alongside the venue, 12 to 18 months out. Request quotes from at least three, and ask to see complete galleries rather than curated highlights.
- Guest list draft: you do not need final names, you need an order of magnitude. Without a headcount, venue and catering quotes are not comparable.
- Catering and tasting: decide after the tasting, not from the price list. Ask specifically about service charges, staff overtime rates and minimum spend.
- Band or DJ: hear them live rather than on a showreel. Popular acts lose peak-season Saturdays before anything else in their calendar.
- Wedding dress: nine months is not early once you account for production and two or three fittings. This is the one item where the lead time, not your indecision, sets the deadline.
The legal and ceremony admin
Marriage licence rules vary widely by country and often by region, so check your local authority early rather than assuming. Two things are usually true regardless of where you marry. First, there is a waiting period between giving notice and the ceremony, which can be anything from a couple of days to a month or more, and licences frequently expire if unused. Second, popular ceremony slots and officiants book out months ahead, especially Saturdays in peak season. Treat the ceremony booking as part of the 12 month window alongside the venue, and treat the paperwork itself as a separate deadline you diarise once you know the local rule.
6 to 3 months: invitations, RSVPs and seating
- Design and print invitations around six months out. Order roughly 12 to 14 weeks before the day so print and delivery delays do not eat into your mailing window.
- Mail the invitations about three months before the wedding. The accepted minimum is 6 to 8 weeks, and 9 to 10 weeks for overseas guests, so three months gives you real breathing room.
- Set an explicit RSVP date, typically 3 to 4 weeks before the wedding. Without a stated deadline a large share of replies slips to the last few days, and you lose the calm week you needed for the final headcount.
- Order the cake and sign off the floral plan. By this point you know your approximate numbers and your table count.
- Draft the seating chart from the replies you have. The first version will change, but it is also the fastest way to see who has not answered.
The final month and the wedding week
- One month out: hair and makeup trial. Book it early enough in the month that you can change stylist if the result is not right.
- One month out: final confirmation with every vendor. Get arrival times, the exact address and the running order in writing, not over the phone.
- 1 to 2 weeks out: chase non-responders and submit your final headcount. Most contracts allow numbers to go up after this point but not down, so read the clause before you guess.
- Wedding week: hand the final seating chart to the catering team and clear remaining balances and tips.
- Wedding week: give a one-page run sheet to everyone with a job on the day. It is the single best way to stop your phone ringing during getting-ready.
If you have less than a year, the order stays the same and only the gaps compress. Book whatever is one-per-day first, meaning venue, photographer, caterer and band, then move to invitations, flowers and cake, which can be turned around faster. Wedding Co-Pilot does this arithmetic for you: enter the date and every task gets its own deadline, sorted by what is most urgent.
Frequently asked questions
How far in advance should you start planning a wedding?
About a year is typical. The average US engagement is 15 months (The Knot 2025 Real Weddings Study), and in practice it is the venue, photographer and caterer that need the full 12 months. Most other tasks fit comfortably into a shorter runway.
When should you book the venue and photographer?
Around 12 months out, and The Knot suggests 12 to 18 months for both. The venue fixes your date and guest ceiling, and photographers can only shoot one wedding a day, so peak-season Saturdays disappear first.
When should wedding invitations be sent?
About three months before the day. The standard etiquette minimum is 6 to 8 weeks, rising to 9 to 10 weeks for guests travelling from overseas, so mailing at three months leaves comfortable room to collect replies.
When is the final headcount due to the caterer?
Usually 7 to 14 days before the wedding, though your contract is the real authority. Set the RSVP date 3 to 4 weeks out so you have a week or two to chase the people who have not replied.
When should the RSVP deadline be?
Three to four weeks before the wedding, or five to six for a destination wedding or a holiday weekend. That gap exists so you can follow up with non-responders before the caterer needs your confirmed numbers.
What if you only have six months to plan?
Use the same order, compressed. Secure the things that only exist once per date first: venue, photographer, caterer, band. Invitations, flowers and cake all work on shorter lead times, and mailing invitations at the 6 to 8 week minimum is still within etiquette.
