A wedding planning timeline, month by month

A timeline built on dependencies

Most wedding timelines are lists of tasks attached to months. They are useful, but they hide the reason behind the order, which matters when your wedding does not fit the standard shape: a shorter engagement, a celebration over three days, guests flying in from abroad, or two traditions to honour.

This timeline is organised around dependencies. Some decisions unlock others: you cannot book a caterer without a date and an approximate headcount, and you cannot finalise seating without replies. If you understand which decisions come first, you can compress or stretch the timeline to fit your situation without missing anything.

The months below assume roughly a year of planning. If you have less time, keep the order and move faster; if you have more, use it to book in-demand suppliers early.

Twelve months or more: the foundations

The first decisions shape everything else, so take them deliberately. Agree the total budget and who is contributing what. Sketch the guest list, at least as approximate numbers for each side and each function. Decide the shape of the celebration: one day or several, which ceremonies, which traditions.

With those in hand, choose the date and book the venues. Popular venues and dates go early, and for multi-function weddings you may need more than one venue, each with its own availability. Once the date is fixed, book the suppliers who can only be in one place at a time and are most in demand where you are, often the photographer, the caterer and the officiant or celebrant.

1. Agree the total budget and contributions.
2. Draft the guest list, with numbers per function.
3. Decide the functions and traditions the celebration will include.
4. Set the date, checking holidays and observances for both families.
5. Book venues, then the most in-demand suppliers.

Nine to ten months: tell people early

Once the date and venue are certain, send save-the-dates. This matters most for guests who travel, need visas, or must arrange leave from work, so if many guests are coming from abroad, send them earlier rather than later. A simple wedding website with the date, location and travel basics gives guests somewhere to look while details are still forming.

This is also the time for decisions with long lead times: attire that needs to be made or altered, any traditional fabrics ordered in coordinated colours for family groups, and accommodation blocks near the venue.

Six to eight months: the supporting cast

Book the remaining suppliers: music, decor and flowers, hair and makeup, transport, rentals and stationery. For each, record the quote, what is included, the deposit and the payment schedule, and set reminders for each payment date. This is the stage when budgets most often drift, as each booking is a little more than planned.

Start shaping the day itself. Draft a rough order of events for each function, and talk to the venue about the layout: where the ceremony happens, where guests eat, where the dancing takes place, and the step-free route through it all.

Four to five months: guest list and invitations

Finalise the guest list, household by household, with every person named where you can. Decide plus-one and children policies and apply them consistently. For multi-day weddings, record which guests are invited to which functions.

Design and prepare invitations, and build the reply form at the same time. Decide what you need to ask: attendance per person and per function, meal choices, allergies, access needs, travel plans. Set the reply deadline working backwards from when your caterer needs final numbers.

The reply deadline is set by your caterer, not by etiquette. Find out when they need final numbers, then set your deadline about three weeks earlier.

Two to three months: invitations go out

Send invitations. Guests who travel need more notice than local guests, so do not leave it too late. As replies arrive, keep an eye on headcounts per function and on meal choices, and share running numbers with your caterer so there are no surprises.

Confirm the details with each supplier: arrival times, what they need from you, who their contact is on the day. Start the legal arrangements for the marriage, because requirements and timings vary a great deal between countries and sometimes between regions, and some need appointments well in advance.

One month: the details come together

Chase outstanding replies a week before the deadline and again just before it. Once replies are in, give final numbers to the caterer and venue, and build the seating plan for each function that has assigned seats, starting with households, guests of honour and anyone with access needs.

Write the detailed run of show for each function: times, who does what, and who to call when something changes. Share it with suppliers and with the people helping on the day. Make the remaining supplier payments as they fall due, and keep a record of each one.

• Final numbers to caterer and venue, per function
• Seating plans published, with place cards ordered from the final version
• Run of show shared with suppliers and helpers
• Payments due this month made and recorded
• Legal documents and appointments confirmed

The final fortnight

Late changes will happen: a cancellation, an unexpected guest, a supplier asking to arrive earlier. Make each change in one place and make sure the seating plan, the catering numbers and the door list all reflect it.

Prepare for the day itself. Brief the people managing arrivals, give them the guest list and a way to look up seats, and agree who handles problems. Pack an emergency kit, confirm transport for the couple and key family members, and hand the run of show to someone who is not getting married so you do not have to manage it yourselves.

After the wedding

Close out the budget as final invoices arrive, and return any rented items on time. Gather photos from guests and from the photographer into one place. Send thank-you notes, ideally to the people who actually attended and to those who sent gifts, within a few months.

If you used an online guest list, export or archive it. It will be useful for anniversary celebrations and, eventually, for addressing other people’s invitations.

Adapting the timeline

With six months, keep the order but compress each stage: venue and date first, then the essential suppliers, then invitations as soon as the details are firm. With three months, be prepared to choose from what is available and to keep the celebration simpler.

For multi-day and multicultural weddings, add time at the start for the conversations between families about which traditions each function will follow, and at the guest list stage, because per-function invitations take longer to prepare. Attergo’s wedding templates arrive with the functions, tasks and reply questions for these celebrations already set up, but the order of decisions here is what keeps any wedding on track.
