Wedding Planning Checklist: What to Do and When (Without Losing Your Mind)
The week after you get engaged, the congratulations texts start to slow down. The excitement settles into something quieter. And then: the small panic. You know you need to do things. In some order. But nobody hands you a manual. So you Google "wedding planning checklist" and find a 47-item PDF from 2019 that starts with "choose your colour palette." You close the tab.
This post is what you needed instead.
It's not a list to print and tick off. It's a timeline that explains what to do, when to do it, and (most importantly) why each thing has to happen in that order. Skip the order at your peril. Every wedding decision sits on top of the one before it.
A note before we start: wedding timelines work backwards from your date, not forwards from today. If you're getting married in eight months, you're not standing at "12 months out" reading the first paragraph and slowly working your way up. You're at "8 months out" and trying to do a year of work in a tighter window. That's fine. Most things compress. A few don't. Photographers, in-demand venues, and bespoke dresses are the three that cannot be rushed.
Here's how the months actually shake out.
12+ Months Out: Three Decisions That Lock Everything Else
Almost every wedding regret starts here. Couples skip this phase, jump straight to scrolling florists on Instagram, and three months later realise they made $20,000 worth of decisions in the wrong order.
Don't do that. There are only three things you need to do this far out, and they need to happen in this order.
Set the total budget. Before the venue. Before anything. You and your partner sit down somewhere that isn't your couch (couches make everyone too relaxed for a money conversation), and you agree on a number. If family is contributing, get the number from them in writing too. "We'll help with the wedding" is a sentiment, not a budget. "$15,000 toward the wedding" is.
This number is the floor for every decision after it. We've written about how to actually set a wedding budget in more depth. Short version: pick a number, add a 10% buffer, and don't let yourself spend over it without a real conversation.
Book the venue. The venue does two jobs at once. It locks your date, and it sets the ceiling on what your wedding is going to feel like. A $15,000 venue commits you to a catering standard, a guest count range, and an overall spend level you won't be able to walk back from. Get the venue right and the rest of planning gets easier. Get it wrong and you'll spend the next eight months trying to make the wedding fit the room.
Tour at least three. Ask each one for the all-in price including setup, packdown, corkage, extra hours, and anything else they normally list as "additional." A "$5,000 venue" routinely becomes $8,000 the second you read the fine print.
Book the photographer. This is the vendor couples regret not booking earlier more than any other. Good photographers in popular markets book out 12 to 18 months in advance, sometimes longer. By the time you're at 6 months out and trying to find someone, you're either picking from the photographers nobody else wanted or paying a premium for the last available Saturday in your range.
The photos are the only thing from your wedding that you'll still look at in twenty years. This is not the place to wait.
9 to 12 Months Out: The Big-Money Decisions
Three more big ones. None of them are about colour palettes.
Lock in catering. This is the cost that scales with your guest list. Every person you invite is $80 to $150 walking through the door, depending on what you serve and where you live. The conversation about catering style (cocktail, buffet, plated, alternate drop) is also a conversation about your total budget, because the per-head difference between a buffet and a multi-course plated dinner can be $50 a person. At 100 guests, that's $5,000.
Most venues either include catering or have a list of preferred caterers. Don't assume the included option is the cheapest or the best. Get an itemised quote and compare it to one outside option. Sometimes the venue's caterer is the right choice. Other times you find out the included buffet is priced $40 a head over what you'd pay locally.
Start the guest list. This is the actual conversation that drives every other number. Most guides treat the guest list as administrative. It isn't. The guest list is your budget.
Adding 20 people is $3,000 you didn't have before. Cutting 20 from the list pays for the photographer upgrade you've been quietly hoping for. The real conversation isn't who to invite. It's who not to.
Sit down with your partner and write three columns: must invite (you'd be hurt if they didn't invite you), want to invite (you'd want them at the table beside you), and obligation (someone, somewhere, expects them to be on the list). Cut from the bottom. Every obligation invite costs the same as a must-invite, and contributes nothing to the night.
Order the dress (if you're wearing one). Most wedding gowns take 4 to 6 months to make. Add another month for alterations. If you want a custom designer or a brand with long lead times, double those numbers. Couples who wait until 4 months out either pay rush fees or settle for what's in stock.
If you're not wearing a gown, this is when you figure out what you are wearing. Custom suits also have lead times. Off-the-rack is faster but still needs alterations.
6 to 9 Months Out: When Everything Starts Happening at Once
This is the phase where the wheels start to feel like they're spinning. You're not making one big decision. You're making fifteen smaller ones, in parallel, and most of them depend on the others.
Music. Florist. Hair and makeup trial. Stationery design. Wedding website. Ceremony details. Save-the-dates going out. The budget being updated as quotes come back. The guest list being adjusted as new addresses come in. Your partner's mum sending you a forwarded article about wedding favours.
If you're doing all of this without a planner, our guide to planning a wedding without one covers which parts you can handle yourself and where a day-of coordinator is worth the spend.
This is where most couples' planning systems start to break. You started with a Google Sheet. You added a Notion page for the guest list. You moved the budget to a different sheet because the first one got too crowded. You and your partner are working off different versions and one of you is convinced the florist is booked when she actually isn't.
This is the problem Mamahinga was built for. The checklist adapts to your wedding date, not a generic 18-month template, so a task only shows up when it's actually time to do it. Booking a vendor in the supplier section ticks the matching task off your checklist automatically. Both partners see the same view, in the same place, updated in real time. You stop juggling tabs and start planning a wedding.
A few practical things to get done in this stretch.
Send save-the-dates. Six to eight months out. Earlier for destination weddings or international guests who need to book flights. Save-the-dates don't need to be formal. A digital one with a link to your wedding website is enough.
Book your music. A great DJ books out a year in advance. A great band books out further. If you want either, lock them in now.
Lock in the florist. Get three quotes. Florists vary wildly on price for nearly identical arrangements. Tell them your budget and let them work to it, instead of building the dream board first.
Hair and makeup trial. Always book the trial. It costs $100 to $200. It's the only way to know you'll love the result on the day, and it's also when you find out your hair person is impossible to be around. Better to know now.
Order the rings. Wedding bands take 4 to 8 weeks if you're sizing up or going custom. Don't be the couple chasing this three weeks before the wedding.
3 to 6 Months Out: The Invitation Window
This is when planning shifts from "decisions" to "execution." You've made most of the choices. Now you just have to do the things.
Send invitations. Six to eight weeks before the wedding for local guests. Eight to ten weeks if guests are travelling. The RSVP deadline goes on the invitation, four to six weeks before the wedding. Most people will not reply by it. That's normal.
Finalise the ceremony. This is where you decide what your actual wedding (not the reception) will look like. Officiant or celebrant. Vows, written or traditional. Readings and who's reading them. Music for the processional and recessional. If there's an aisle, who you're walking down it with, and how long the ceremony runs. Your celebrant will walk you through most of it if you ask. (If you haven't chosen a celebrant yet, the guide to choosing the right one covers what to ask and how to spot someone worth booking.)
Confirm vendor details. Most vendors won't chase you. They'll just turn up and do whatever the original quote said. Six weeks out, send each one a short email confirming time, location, contact details, and any updates since you booked. This catches problems early.
Plan the seating chart, but don't finalise it. You can sketch the structure. You can decide table sizes and where the head table goes. Don't start placing names until your RSVPs are mostly in. Every couple who builds a finalised seating chart at the four-month mark ends up rebuilding it three times.
1 to 3 Months Out: The Chase Phase
Most of what happens here is following up.
Chase RSVPs. People won't reply by the deadline. We've written a whole guide on the RSVP chase, but the short version: a casual group message at one week post-deadline, a direct text or call at two weeks, and a decision to count them as a "no" at three.
Final dress fittings. Two fittings minimum, three if your weight has changed. Bring the shoes you're actually wearing. Bring the underwear you're actually wearing. The dress hangs differently with both.
Build the seating chart. Once most of your RSVPs are in, this becomes possible. We've covered how to do a seating chart without losing your mind. Don't finalise it until two weeks out. Someone always cancels.
Day-of timeline. A document that lists every minute of the day, who needs to be where, and who's responsible for what. Send it to all your vendors and your wedding party. The day runs on this document.
Marriage licence. Rules vary by where you live. Some places require it weeks in advance. Don't assume.
The Final Two Weeks
Almost everything is locked. What's left is communication.
Final headcount to the caterer. Usually 7 to 14 days out. Once this number is locked, you can't reduce it. You can sometimes add. Always ask.
Seating chart finalised. Print it, or load it into whatever tool the venue uses. Bring a printed copy to the rehearsal as a backup.
Vendor confirmations. A final email or call to each one. Time, location, contact details for the day. Most problems on the wedding day come from a vendor not knowing where to be at what time.
Pack everything. Rings, vows, marriage licence, day-of outfits, anything sentimental. Make a list. Get someone reliable to be in charge of the box.
Rest. The week of the wedding is not the time to be cleaning your house, finishing work projects, or organising anything new. Block the week out. Let the planning be done.
What's Not on This Wedding Planning Checklist
You'll notice a few things missing. The colour palette task isn't here because nobody actually needs one. There's no "design the program" task because most modern weddings don't have programs anymore. And the elaborate "send a thoughtful gift to your wedding party at month 11" thing every other guide includes? Not a real tradition. Someone made it up.
The 47-item PDFs are that long because they're padded. They include every possible task that any wedding has ever included, in case you happen to want one. The result is a list that feels exhausting to read, and the actually important things get lost in the noise.
The list above is the real sequence. Everything else is optional. If you want the full month-by-month map that explains how all these pieces connect, our how to plan a wedding guide walks through the entire arc from engagement to the morning of.
After the Wedding
One final task: thank you notes. Not gifts for your wedding party (those are optional, not tradition). But thank yous to your guests, your family, and your suppliers who made the day happen. The guide to writing and sending thank-you notes covers the formula that keeps it from dragging past Christmas.
The checklist is the skeleton. The decisions are the hard part. The list won't tell you whether to invite your partner's college roommate or whether you can afford the upgraded floral arrangement. It only tells you what to do next, so you have the headspace to think about what actually matters. Don't let the list become the goal. The goal is the evening you're building, the people who'll be in the room, and the version of your life that starts the morning after.
