Wedding planning timeline: month by month

In brief: how long does it take to plan a wedding?

French couples genuinely start planning their wedding 13 months before the big day. That is the median observed across 1,408 wedding projects posted on Planners (Planners data, August 2026), not the “18 months” that most online timelines repeat. That gap changes everything: if you are 10 or 11 months out, you are not behind, you are normal. Three decisions, on the other hand, cannot be recovered — the venue, the caterer and the date — and those are the ones that have to be settled first.

Lead time actually observed: median 13.1 months before the wedding (n = 1,408 projects).
58% of couples start 12 months out or more; 16% start with under 6 months to go — a wedding can be pulled together in 4 months.
The 3 structural bookings: venue, caterer, photographer. Everything else can be adjusted.
The only genuinely fixed delay is a legal one: in France, the banns are published for 10 days (service-public.gouv.fr).
737 active wedding planners are listed on Planners if you would rather delegate this timeline.
The full month-by-month timeline is summarised in a table at the end of the article.

A wedding planning timeline is a calendar read backwards: you start from the wedding date and work back in time to place each decision at the moment it needs to be taken. The exercise looks like homework, but it solves the one real problem in organising a wedding: some decisions block others. You cannot choose your caterer before your venue, or your table plan before the replies to your invitations.

The trouble with the timelines you find online is that they are all identical, all generic, and not one of them is based on what couples actually do. So we started by looking at our own data before writing a single line of this calendar.

When couples really get started (Planners data)

We measured the gap between the date a wedding project is posted on Planners and the wedding date itself, across 1,408 dated projects (Planners data, August 2026, outliers of under 14 days excluded). The result:

Median: 13.1 months before the wedding. Half of couples start earlier, half later.
25% start more than 18.7 months out — the very early planners, often with sought-after venues or summer dates in mind.
25% start with less than 8.5 months to go.
58% start 12 months out or more.
16% start with under 6 months to go, and get married all the same.

That figure is worth comparing with the industry’s own benchmarks: the annual Mariages.net report puts preparation at around 15 months on average, and virtually every timeline published online starts at 18 months. An average is always pulled upwards by couples who begin two years ahead; the median, by contrast, describes the typical couple. And the typical couple has a little over a year.

Two practical consequences. If you are reading this 11 months out and feeling behind, stop: you are exactly where French couples usually are. And a timeline that only starts at 18 months is unusable for a quarter of couples — hence the section further down devoted to compressed schedules.

The real question is not “do I have enough time?” but “in what order do I decide?”. A wedding prepared in 6 months in the right order goes better than one prepared in 18 months in the wrong one.

12 months out: the 3 bookings that determine everything else

A year before the wedding, most of your energy should go into three commitments. Everything else can wait, and wait without consequence.

1. The budget and the guest count, before anything else

These two numbers are not one step among many: they are the frame for every decision that follows. A magnificent venue for 60 people becomes a problem the moment the guest list reaches 120. Among couples posting a project on Planners, half (51%, n = 743) expect between 50 and 100 guests, and only 3% go beyond 200 people. Set an upper and a lower figure, not a single number.

If you have no idea what envelope to allow for, start with a costed estimate: our wedding budget calculator gives you a realistic range in two minutes based on your region, your guest count and your reception style.

2. The reception venue

This is the most constrained booking of all, and the one that locks in your date. The most in-demand estates and châteaux are fully booked 15 to 24 months ahead for Saturdays between May and September. If your date is flexible, a Friday or a Sunday, or a date outside the season, opens up a far wider choice — and often a lower price. Booking lead times vary considerably from one type of venue to another, so ask each one directly how far ahead its diary is filled.

3. The caterer and the photographer

The caterer comes straight after the venue, because many estates impose a closed list of suppliers: check this point before you sign, not after. The photographer, for their part, cannot be duplicated: a photographer has only one 20 June 2027 to sell. The most sought-after names are booked 12 to 18 months ahead.

This is also the moment to decide whether you want help. A wedding planner on a full-planning package typically works over 12 to 18 months; beyond that point, their scope shrinks mechanically. Our wedding planner directory lets you compare approaches and packages before you commit.

9 months out: the shape of the day

The skeleton is in place, now you fill it in. This is the most comfortable stretch of the whole timeline: nothing is urgent, everything is available.

Send the save-the-dates, especially if guests are travelling from far away or the date falls during the school holidays.
Book the DJ or the band — the same scarcity logic as the photographer.
Start dress and suit fittings. Allow 6 to 8 months between ordering and delivery for a made-to-measure dress, alterations included.
Choose your witnesses and your celebrant if you are planning a non-religious ceremony: they need time to write.
Book accommodation near the venue, reserving a block of rooms.
Pin down the videographer, the florist and the cake if you have something specific in mind.

This is also the ideal window to review your budget a second time: with three signed quotes in hand, the initial estimate finally meets reality, and cutting a line item is far easier now than it will be in three months’ time.

6 months out: the details that take time

At six months you leave the big decisions behind and move into execution. Be warned: this is the phase where couples systematically underestimate production lead times.

Order the invitations (allow 3 to 6 weeks for production and dispatch) and prepare the envelopes.
Do the catering tasting and finalise the menu, drinks included.
Choose the wedding rings. Engraving or handmade rings take 6 to 10 weeks.
Book hair and make-up, and fix a date for the trials.
Plan the ceremony: readings, music, running order, participants.
Book the honeymoon and check that your passports are valid.
Contact the town hall (mairie) to find out how it wants your marriage file submitted.

That last point deserves more anticipation than the others. In France, town halls do not all work the same way, and some urban councils require an appointment booked several weeks in advance simply to lodge the file. A five-minute phone call six months out will save you a nasty surprise two months out.

3 months out: paperwork and the table plan

This is the busiest quarter, and the one generic timelines handle worst, because it mixes creative tasks with legal obligations that are not up for negotiation.

The marriage file at the town hall

In France the national rules are clear, even if the submission timetable varies from one council to another. According to service-public.gouv.fr:

The banns are displayed for 10 days at the door of the town hall, and the marriage cannot be celebrated before the 10^th day following that publication.
The birth certificate must be less than 3 months old on the day the file is lodged (for a certificate issued in France).
The proof of address must establish residence in the commune for more than a month: what article 74 of the French Civil Code requires is that month of continuous residence — not that the document itself be recent.
An interview with the registrar is part of the procedure for both partners.

In practice, lodging a complete file two or three months before the wedding keeps you safe: the real constraint is how long your town hall takes to give you an appointment, not the law itself. Ask your council for its list of required documents as soon as you make first contact — it is the one piece of paperwork nobody can speed up for you.

The rest of the quarter

Send the invitations with an RSVP deadline set at 6 weeks before the wedding.
Do the hair and make-up trials.
Order the decoration, the on-the-day stationery and any favours.
Draw up the table plan — impossible before the replies come in, so start once 80% are back.
Sort out transport for guests between the ceremony, the drinks reception and the dinner.
Take out cancellation insurance if your budget is significant.

The final month, week by week

With a month to go you stop adding and start closing. Any new idea introduced in the last four weeks is expensive, in money and in stress.

Week 4 (30 days to go): chase the guests who have not replied, confirm the final headcount, pay the outstanding deposits.
Week 3 (21 days to go): give the final number to the caterer (most ask for it 10 to 15 days ahead), finalise the table plan, prepare the speeches.
Week 2 (14 days to go): last fitting with shoes and accessories, send the running order to every supplier, brief the witnesses.
Week 1 (7 days to go): confirm every supplier by phone, prepare the payment envelopes, pack for the honeymoon, sleep.

The single most useful document in the whole timeline is written here: the minute-by-minute running order for the day, with the name and mobile number of every participant alongside each slot. That is the document everyone will be consulting on the day — including you, when you have forgotten what time the florist arrives.

Wedding week and the day itself: who runs what

The rule is simple and rarely respected: the couple runs nothing on the day. If your phone rings during the couple portraits because the DJ is looking for a socket, the organisation failed upstream.

So you need to appoint someone explicitly, and only one person:

A professional coordinator — this is exactly what the “day-of coordination” package offered by most wedding planners is for: the planner does not prepare your wedding, they run it on the day.
A witness or a willing friend, provided you give them the running order, the contacts and genuine authority to make decisions.
The venue’s own contact, if your estate provides one — but their remit generally stops at the building.

The week beforehand follows the same logic: deliveries, setting up the decoration, collecting outfits and greeting guests who arrive early can all be delegated.

Compressed timelines: 6, 4 or 3 months

A quarter of the couples posting a project on Planners start with less than 8.5 months to go, and 16% with less than 6 months. These weddings happen, and they go well. The principle of a compressed timeline is not to do everything faster: it is to give up certain options explicitly in order to protect the others.

In 6 months

Lock down venue, caterer and photographer within the first fortnight, accepting that you will give ground on the date: a Friday, a Sunday or an off-peak date multiplies your options. Send the invitations straight out, with no save-the-date. Choose a dress off the peg or from a boutique with stock, not made to measure.

In 4 months

Every booking happens in the first month, without exception. Make the town hall file your absolute priority from week one, since it is the only delay nobody can shorten. Reduce the number of suppliers: a caterer who also supplies the furniture and crockery saves you two negotiations.

In 3 months

The format has to fit the timescale: a more intimate reception, a venue that handles everything in-house, a weekday. This is also the scenario in which professional help pays for itself fastest — a wedding planner used to working with a local network will find in three phone calls what would take you three weeks. Just check, when you contact them, that they accept short lead times: not all of them do.

The complete summary table

Here is the whole timeline, condensed. The lead times shown are safety margins: if your date is off-season or midweek, you can usually cut them by a third.

This calendar is a framework, not a prescription. The only thing you cannot recover from is a venue already booked for your date; everything else can be adjusted. And if the exercise weighs on you, this is precisely a wedding planner’s job: 737 active wedding planners are listed on Planners, from coordinating the day itself to full planning over twelve months.

One last habit: cost it before you book. Even a rough estimate will stop you falling in love with a venue that would swallow half your budget on its own. Our wedding budget calculator is free and gives you a range in two minutes.
