Wedding planning timeline: due dates from your wedding date

A wedding planning timeline counts back from your wedding date. Set the budget a year out, sign the venue about ten months out, mail invitations eight weeks out. Enter your date above and every step gets a calendar due date. Below is the same math worked for a sample date, Saturday, June 12, 2027.

Date table for a June 12, 2027 wedding

This is what the tool computes for that date. Find the row, add the due date to your calendar, and move on. Months count back by calendar month. Weeks count back in blocks of seven days.

Notice the cluster at ten months. Venue, photographer and caterer all fall on the same day. That is on purpose. Those three have the fewest open dates, so they share one deadline.

Tick them off, with the reason for each

Each step below has the reason it sits where it does and a rough time to finish it. The times are our own guesses for one person, so treat them as a floor.

1. 12 months out: set the budget and who pays. Every later choice draws on this number, and a family contribution changes it. About an hour with whoever is contributing.
2. 12 months out: draft the guest list in two tiers. Headcount sets the venue size and the catering bill. Two tiers let you cut by group later. About two hours.
3. 11 months out: tour three venues with one question list. Asking everyone the same questions makes the quotes comparable. Plan a day for three tours.
4. 10 months out: sign the venue contract and pay the deposit. Nearly every other date depends on this one. Read the date-change and cancellation terms first. About two hours.
5. 10 months out: book the photographer. A good one holds your date only once you pay. Look at full galleries, not highlight reels. About three hours.
6. 10 months out: book the caterer, if the venue does not supply food. Ask for a tasting date and the date they need your final count. About two hours.
7. 9 months out: ask the wedding party. People need time to plan travel and outfits. Ask in person where you can. About an hour.
8. 9 months out: order the dress or suit. Made-to-order gowns take months to arrive, and alterations come after. Confirm the lead time with the shop. About half a day.
9. 9 months out: book music: DJ or band. The day-of schedule needs their set times. Ask about overtime and equipment needs. About two hours.
10. 8 months out: book hair and makeup. Stylists take few brides per morning, and the trial needs a date. About an hour.
11. 7 months out: mail save-the-dates. Guests who must travel or take leave need the date first. About two hours once the addresses are ready.
12. 6 months out: book florist, cake and rentals. These bookings depend on the venue and menu you already chose. About three hours.
13. 6 months out: book travel and check passports. A honeymoon abroad needs a valid passport, and renewals can be slow. About an hour.
14. 5 months out: check marriage license rules for your county. Waiting periods, fees and validity windows vary by place. Read the county clerk's page. About 30 minutes.
15. 5 months out: draft invitation wording. Hosting and naming take family conversations, and those take time. About an hour.
16. 4 months out: order invitations. Printing and addressing need a proof round. About two hours plus the print shop's turnaround.
17. 4 months out: hold the menu tasting. You still have room to change dishes. About two hours.
18. 3 months out: confirm the dress has arrived. If it is late, you want to hear now, not at the first fitting. One phone call.
19. 10 weeks out: first dress fitting. Bring the shoes and undergarments you will wear. About an hour.
20. 8 weeks out: mail invitations. This starts the RSVP clock. Check every address twice. About three hours.
21. 8 weeks out: start writing vows. A first draft written early gets edited into something good. About an hour for a draft.
22. 5 weeks out: second dress fitting. The bustle lesson belongs here. Tell whoever will bustle it to come. About an hour.
23. 4 weeks out: RSVP deadline. Chase late replies by message first and phone second. Count heads, not envelopes.
24. 3 weeks out: send the final headcount and build the seating chart. Confirm the caterer's own due date, because it differs. About three hours.
25. 3 weeks out: send the day-of timeline to every vendor. Everyone then works from the same arrival times. About an hour.
26. 2 weeks out: final dress fitting and pickup. Try it on fully dressed and walk in it. About an hour.
27. 2 weeks out: confirm every vendor and pay final balances. Check the contracts for due dates and tips. About two hours.
28. 1 week out: pack the emergency kit and print signs. Decide who carries the kit. About two hours.
29. 1 day out: rehearsal and rehearsal dinner. Walk the ceremony once with the people who have a role. About two hours.
30. Wedding day. Your only job is to follow the timeline someone else holds.
31. 4 weeks after: send thank-you notes. A note written while the gifts are fresh is shorter and warmer. About two hours.

The hour-by-hour plan for the day itself lives in the day-of schedule planner. Hand it to vendors at the 3-week mark.

Three dates that move everything else

Thirty-one steps look like a lot. Three of them carry the rest.

The venue date. The photographer, caterer, music and florist all ask which venue and day you have. Until it is signed, those four cannot start. The questions to ask on each tour cover deposits, due dates, cancellation terms and the bad-weather plan. Settle those before you sign.

The invitation mail date. It sets the RSVP deadline, which sets the headcount, which sets the catering order and the seating chart. Slip the mailing by two weeks and every date after it slips too. Use these wording options early so printing never holds it up.

The final count date. Your caterer owns this one, not you. Ask for it in writing when you book. It tells you when your seating chart must exist, and the seating chart maker takes an afternoon once the RSVPs are in.

The same three dates drive your money. The budget planner shows how a total divides across categories, and deposits for the venue, photographer and caterer are the first three cash outflows on this timeline.

Where the offsets come from

Not every number here has a source, and we want you to know which ones do.

Sourced offsets:

• Save-the-dates: 6 to 8 months before for a standard wedding. We use 7.
• Invitations: 6 to 8 weeks before. We use 8. Zola advises an earlier window of about 3 to 4 months, and its own page disagrees with itself, so treat that as the early option.
• RSVP deadline: 3 to 4 weeks before. We use 4.
• Dress order: 8 to 12 months before, with arrival 2 to 3 months out. We use 9 and 3.
• Fittings: two or three, from about 8 to 10 weeks out to the last week or two. We use 10 weeks, 5 weeks and 2 weeks.

Our own judgment: the venue, vendor, license and tasting dates. They follow one idea, which is that fewer available options means an earlier deadline. If a vendor says to book later or earlier, trust the vendor over this page.

One boutique reports a rush alteration fee of around $150 or 25% of the alterations total when a wedding is within about six weeks. That is one shop’s policy, not a rule. It does show what a late fitting can cost.

If your wedding is closer than 12 months

Most couples do not start at exactly 12 months out. Keep the order. Shorten the gaps.

Take the same June 12, 2027 date and say you start planning on Saturday, December 12, 2026, which is six months out. Ten steps have already passed. Compress them in order of how few options each has.

Two things to know about the example. First, the order is the strategy: the list runs from the fewest-options step to the most. Second, the dress is the risky one. Made-to-order gowns can run late at this point, so ask about in-stock or sample options.

For a wedding inside the last month, use the last minute checklist for the final month. It drops everything that has already closed.

Three mistakes that break a timeline

Mistake one: treating all steps as equal. A florist booked late costs you a choice of flowers. A venue booked late can cost you the date. Work the ten-month cluster first, and let the rest follow.

Mistake two: keeping one copy. If one person holds the dates, the other finds out about the deposit when the vendor calls. Print the table, or send it, and agree on who owns each row.

Mistake three: skipping the thank-yous. They sit at the end, so they get dropped. Put them on the calendar now. The thank-you note wording by gift type makes each one a short job.

Planning the dates is the part you can do in an evening. Doing the steps is the long part, so give each one an owner and a day.
