Wedding Planning Checklist: Month-by-Month Timeline

The short answer

Twelve months out, agree the budget and guest count. At eleven months, book the venue. At ten, book the caterer and photographer. Between eight and six months, sort music, attire, the guest list, save-the-dates and flowers. At three months, set the RSVP date; send invitations at ten weeks; seat people three weeks out; confirm vendors and final numbers two weeks before.

A wedding checklist is only useful if it tells you what to do next. Most printable lists give you sixty tasks and a vague heading like "6 to 9 months". This one gives each task a point in time and a reason, and it keeps one rule that the long lists ignore: nothing lands before the thing it depends on. You cannot send invitations before you have a venue and a guest list, and you cannot seat people before they have replied.

The timings below are the same ones our free wedding checklist by date uses. Enter your date there and every line below gets a real calendar date, with the things you have already booked ticked off.

12 months before: the budget and the guest count

These two decisions shape everything else, so they come first.

Agree an initial budget. Every booking after this is a choice about money, so settle the total before you visit anything. Find out who is contributing and how much. Our guide to who pays for what helps with that conversation.
Estimate your guest count. Venues and caterers price and size everything by it. A number is enough for now; names can wait.
Shortlist venues. Popular dates go early. Compare a few that fit your count and your budget.

11 months before: book the venue

Book the venue and confirm the date. The date is not real until the venue is. Most other bookings wait on it.

Before you sign, write down the deposit, each payment date and the last day you can confirm numbers. These dates matter later, and our guide to paying wedding vendors shows how to keep them in one place.

10 months before: the vendors who book by date

Confirm catering. Some venues require their own caterer, and outside caterers book up by date.
Book your photographer. They take one wedding a day, so your date decides who is free.

9 months before: the ceremony

Agree the ceremony arrangements. Who leads it and where it happens shapes the timing of the whole day. Check any legal paperwork with whoever marries you.

8 months before: music, attire and names

Arrange ceremony and reception music. Bands and DJs fill Saturdays early, and the venue may have sound rules.
Plan your attire and alterations. Made-to-order clothes can take months, and alterations need fittings after that.
Finalise your first guest list. Names turn the estimate into invitations, and settle any conversations about numbers early. If the list is longer than the budget, our guide to cutting a guest list has a fair method.
Collect contact details. You need an address or number for every invitation, and gathering them always takes longer than it seems.

7 months before: save-the-dates and rooms

Send save-the-dates, if you are using them. They hold the date for guests who need to book time off or travel.
Arrange guest accommodation information. Guests who travel need somewhere to stay before they can say yes.

6 months before: flowers and decor

Plan flowers and decor. Florists plan by season and venue, so they need both before they quote.

The checklist with tasks done and the next things due

5 months before: hair, makeup and the wedding party

Arrange hair and makeup. Artists book by the day, and a trial needs its own date before the wedding.
Agree wedding-party attire. Several people ordering and fitting clothes takes more coordination than one.

Choose wedding rings. Sizing and any engraving can take several weeks.
Agree the menu and how you will collect dietary needs. The menu decides which questions the invitation needs to ask.
Arrange guest transport. Coaches and drivers are booked by the hour and fill up on busy dates.
Plan honeymoon logistics. Passports, visas and fares all move faster than you would like.

3 months before: set the RSVP date

Confirm your RSVP and headcount deadlines. The caterer's headcount date sets the RSVP date you print on the invitation.
Prepare the invitation details. Venue, times and the RSVP date all have to be settled before anything is printed.

10 weeks before: send the invitations

Send the invitations. Guests need time to reply before your RSVP date. Our guide to when to send wedding invitations explains the arithmetic.

8 weeks before: the schedule for the day

Draft the wedding-day schedule. Vendors plan their arrival and setup from it. Our wedding day timeline guide has a worked example, hour by hour.
Prepare vows or readings, if you want them. Words written early can be read aloud a few times before the day.

The last month

When	Task	Why then
4 weeks	Confirm attire fit and collection	A last fitting leaves time for one more change
4 weeks	Follow up on missing replies	A friendly nudge before the RSVP date gets you the final numbers
3 weeks	Draft the seating plan	Tables only make sense once you know who is coming
2 weeks	Confirm vendor arrival details	Everyone needs the address, the access time and a contact on the day
2 weeks	Review the remaining vendor payments	Final balances often fall in the last weeks
2 weeks	Give the caterer your final headcount	Your contract date wins if it is earlier

The seating plan is its own small project. Our seating chart guide has a method that takes an evening.

The last week

Pack documents and day essentials. Rings, paperwork, chargers and any payments due on the day, in one place.
Share the final plan with your point person. Someone else answers the questions on the day, so you do not have to.
Start a thank-you list. Noting gifts and helpers as they come makes the notes after the wedding easy. Our guide to wedding thank-you notes has the schedule for afterwards.

A 6 month or 3 month wedding checklist

Less time does not mean fewer tasks. It means the early ones happen at once. Do them in this order, because each one unblocks the most:

Budget and guest count, in the same week.
Venue, and ask about their caterer and their preferred vendors, because a venue with a list saves you days of searching.
Caterer, photographer and music.
Guest list and invitations. With under four months, skip save-the-dates and send invitations straight away.
Everything else, in the order above.

With three months, be flexible about the day of the week. A Friday or Sunday opens up venues and vendors that are gone on Saturdays. Our checklist tool does this automatically: tasks whose dates have passed are spread from today, the ones that unblock the most come first, and anything that cannot fit is set aside so you can decide whether it still matters. Our guide to planning a wedding in 6 months walks through one, week by week.

Destination weddings

Guests need more time to book travel and rooms, so move the guest list, contact details, save-the-dates, room information and invitations earlier. As a guide, send save-the-dates nine to twelve months out and invitations about four months out. Check your venue's own deadlines for rooms and transport as well. Our destination wedding timeline shows the same wedding planned at home and abroad, date by date.

Keeping the checklist in one place

A checklist on paper does not move when your plans do. When the venue asks for final numbers a week earlier, or the florist needs the colours sooner, every date after it shifts. That is what makes a dated list worth having.

In Yes, I Do, you answer a few questions about your date and what you have booked, and the checklist is dated for your wedding and grouped by what comes next. Your partner sees the same list on their phone and can tick things off too.

Questions

What should be on a wedding planning checklist?

At minimum: the budget, the guest count, the venue, catering, photography, music, the ceremony, attire, the guest list and addresses, invitations and the RSVP date, the seating plan, the schedule for the day, vendor confirmations, the final headcount and the last payments. Everything else is optional and depends on your wedding.

When should you start planning a wedding?

Twelve to eighteen months before the date gives you the widest choice. Start with the budget and guest count, then book the venue about eleven months out.

What is the 30-5 rule for weddings?

It is a rule of thumb for the schedule on the day. Add a 30-minute buffer around each big moment, such as the ceremony and the start of the reception, and allow five minutes for every small move between places. Things that take five minutes on a normal day take much longer at a wedding.

What is the 50/30/20 rule for weddings?

A budget split: about half for the venue, food and drink, about 30 percent for photography, attire, music and flowers, and about 20 percent for everything else, including a cushion for surprises. Treat it as a starting point. Our guide to the average wedding cost shows how real budgets split.

What do people forget when planning a wedding?

The most common ones are service charges and tax on vendor quotes, collecting addresses, dietary needs, meals for vendors who work through dinner, a rain plan for anything outdoors, and someone to be the point person on the day.
