Wedding Planning Timeline: 12 Months, 6 Months, 1 Month

Most wedding planning timelines start at 18 months and list sixty tasks. They are accurate, and slightly exhausting. Worse, they treat every task as equally urgent, when really three or four decisions shape everything else.

Here is our take: a wedding timeline exists mainly to show you what has to be booked early because it sells out. The venue, the caterer, the photographer, sometimes the band. Almost everything else, from invitations to centerpieces to the seating chart, fits comfortably into the last three months, as long as you do not leave it all for the final week.

Below is the timeline we recommend, with the legal paperwork in the right place for US and UK couples.

Where do you start after getting engaged?

Before touring a single venue, agree on three things: a total budget, a rough guest count and a season. Not an exact date. A season is enough.

Those three numbers rule out half the venues immediately. No point falling for a barn that seats 250 when you are inviting 70, or a ballroom that costs most of your budget on its own. If you have no idea what to budget, read how much does a wedding cost first; it works from a per-guest number.

12 months out (or as soon as you can)

This is the big-booking phase. Popular venues on peak Saturdays often book a year or more ahead, especially in late spring and early fall. If you want a June or October Saturday, move quickly.

In this window:

• Book the venue and pay the deposit. Then set the date (the venue usually decides it for you).
• Book the caterer, if the venue does not have one in-house.
• Book the photographer. Good ones fill peak dates early.
• Start the guest list, even a messy one.
• Choose your wedding party, if you are having one.
• If you are marrying in a church or other place of worship, get in touch now. Some require marriage preparation that runs for months.

One thing few timelines mention: before signing anything, ask every vendor about their cancellation and postponement terms. Not pessimism. Protection.

9 to 6 months out

The venue and key vendors are locked in. Now come the choices that give the day its personality.

The rest of your vendors

Band or DJ, florist, officiant, rentals if your venue is a blank space, a videographer if you want one. Hair and makeup artists for peak dates can book up too, so get on their calendars.

Save-the-dates and your wedding website

Send save-the-dates around 6 to 8 months before the wedding, or 8 to 12 months for a destination wedding or a holiday weekend. Put a basic wedding website live at the same time: date, city, hotel block, travel tips. It does not need to be finished. Our guide to what to put on your wedding website covers what is worth having from day one.

Attire

Many bridal gowns take several months from order to final fitting. Start shopping around 9 months out if you want breathing room. Suits and tuxes can wait a little, rentals especially.

Registry

Set it up before the save-the-dates go out, or shortly after: people start looking as soon as they hear the date. If you are torn between gifts and cash, read cash fund vs registry.

4 to 2 months out: invitations and paperwork

Invitations

In the US, the convention is to mail invitations 6 to 8 weeks before the wedding, earlier (around 3 months) for destination weddings. Set the RSVP deadline 3 to 4 weeks before the big day. That gap is what lets you give your caterer final numbers on time. We wrote a whole piece on wedding invitation wording and timing, with sample wording.

The legal side

This is the least romantic part, and the easiest to forget.

In the US, you need a marriage license from the county (or city) clerk where the wedding takes place, not necessarily where you live. Rules vary by state: some have a waiting period between issuing the license and the ceremony, and licenses expire after a set number of days. Check your county clerk's website about two to three months out, then apply inside the valid window.

In England and Wales, you both need to give notice of marriage at your local register office at least 28 days before the ceremony, and the appointment slots can book up. Scotland and Northern Ireland have their own procedures. If you are marrying in the Church of England or the Church in Wales, banns or a church licence usually take the place of the civil notice; your vicar will tell you which applies.

Also in this window: order rings, do a hair and makeup trial, book transportation, and plan any rehearsal dinner.

6 weeks to 1 month out: RSVPs, seating, final numbers

This is the busiest month, and the most concrete.

The RSVP deadline arrives. There are always stragglers. Follow up right away, kindly but clearly, so your numbers are firm. Our tips on how to get guests to RSVP are written for this exact moment.

With a final list, you can:

1. Send the caterer your headcount and dietary requirements.
2. Build the seating chart (give it several evenings, and use our method for seating without drama).
3. Order day-of stationery: menus, place cards, the seating display.
4. Confirm times with every vendor and send them the day-of schedule.
5. Have the final fitting.

Prepare envelopes with final payments and tips for vendors paid on the day. It saves a panicked ATM run on the morning of.

The final week

Little left to decide, a lot to hand off. Ask a friend, a family member or your coordinator to be the day-of point of contact: vendors call them, not you. Give them the schedule, every phone number and the list of what goes where.

On the morning of the wedding, your only job should be getting ready.

The things every timeline forgets

A few tasks never make the glossy checklists, and they tend to surface at the worst moment. Break in your wedding shoes at home weeks before. Write your vows earlier than feels necessary; nobody writes good vows the night before. Decide who gives the toasts and tell them at least a month ahead. Plan how you get home, or to the hotel, at the end of the night. And schedule one evening in the final month that has nothing to do with the wedding. You will both need it.

What if you have less than six months?

More common than you would think, and entirely doable. Picture a couple who decide in February to marry at the end of July. Saturdays at their dream venues are gone? They look at Fridays and Sundays, or a lesser-known venue. Their first-choice photographer is booked? They ask her to recommend someone she trusts.

The method is the same, compressed: venue and caterer in week one, photographer right after, check the license or notice rules immediately (often the least flexible deadline), and skip the save-the-date in favor of invitations sent a little earlier than usual.

The real difference is that you no longer have time to compare five quotes for everything. Give yourselves a rule: two quotes, one decision.

Keeping track without thinking about it every night

A timeline is only useful if it is dated against your wedding. A generic "6 months before" list means redoing the math every time you look at it.

If you want to skip that step, the iPlanMyWedding wedding checklist fills itself in when you enter your date, with deadlines calculated for you and tasks you can split with your partner. A shared calendar with reminders works fine too, as long as you both actually open it.

When are you actually running late?

Only when the venue, caterer and photographer are still unbooked for no good reason. Everything else can be caught up in a few well-organized evenings.
