3-month wedding planning timeline: week by week

By Forever Farrah Published 2026-09-17.

How to plan a wedding in three months, with week-by-week priorities, what to book in the first fortnight, what to simplify, and when to send invitations.

You can plan a wedding in three months if you make every big decision in the first two weeks: budget, guest count, venue and date in week one, officiant, caterer and photographer in week two. Check your marriage license rules immediately, send invitations by week five or six, and keep the rest simple. A smaller guest list and a venue that provides food, furniture and staff do more to make three months workable than anything else.

The rules for a short timeline

• Decide fast, and once. Set a deadline for each decision and take the first option that meets your needs.
• Book one-stop venues. A restaurant, hotel or venue with in-house catering replaces several bookings.
• Keep the guest list short. Every guest adds addresses, replies and seats. See how to cut your wedding guest list, or consider a micro wedding.
• Go digital where you can. A wedding website and emailed save-the-date replace weeks of printing and posting.
• Check the legal side on day one. FindLaw notes that many US states have a waiting period after you apply and that licenses are only valid for a set time, which varies by state. Religious ceremonies can have their own preparation requirements too, so ask early.

Week 12: the big decisions

Agree the budget and who's paying (how to have a wedding on a small budget helps if it's tight), a guest count, and your top priorities. Shortlist venues that have your likely date free. Look up the marriage license rules where you'll marry.

Week 11: venue and officiant

Tour and sign a venue. Book your officiant or confirm with your place of worship. Tell family and the wedding party the date.

Week 10: key vendors

Book caterer (if not in-house), photographer, and band or DJ. What to book first for your wedding explains why these come next.

Week 9: guests

Build the guest list with addresses and email addresses. Launch the website and send a digital save-the-date so people can hold the day.

Week 8: clothes and stationery

Buy wedding clothes off the rack or from sample sales, leaving time for alterations. Order invitations, choosing a ready-made design.

Week 7: remaining vendors

Book florist, hair and makeup, rentals and transport if you need them. The wedding vendor checklist shows which are optional.

Week 6: invitations out

Mail or send invitations now. Six to eight weeks ahead is standard for a local wedding; see when to send save-the-dates and invitations. Set the RSVP deadline about two weeks before the wedding, or whenever your caterer needs final numbers, following when should wedding RSVPs be due.

Week 5: ceremony and details

Plan the ceremony with your officiant. Buy rings. Order the cake or dessert. Book a tasting if your caterer offers one.

Week 4: the running order

Have fittings. Draft the day's timeline with your venue, using the wedding reception order of events. Send the music list to your band or DJ.

Week 3: paperwork

Apply for the marriage license if your local rules allow it this far ahead, and bring whatever identification they ask for. Write vows.

Week 2: numbers and seating

Chase missing RSVPs (what to do when guests don't RSVP), send final numbers and meal choices to the caterer, and make the seating chart. Our last-minute wedding seating chart guide is written for this week. If you want the guest list, RSVPs, meal choices and seating chart in one place, Forever Farrah does that.

Week 1: confirm and rest

Confirm arrival times, addresses and balances with every vendor. Hand the timeline and contacts to one person who isn't getting married. Pack a wedding day emergency kit. Attend the rehearsal and go to bed early.

What to let go

On three months, skip anything that needs a long lead time or a lot of your attention: custom stationery, favours, elaborate décor, a separate welcome event. Most guests remember the food, the company and whether they knew where to sit. How to deal with wedding planning stress has more on keeping it manageable, and the 6-month timeline shows what you'd add with more time.

Frequently asked questions

Can you really plan a wedding in 3 months?

Yes, especially with a smaller guest list and a flexible date. The venue and the vendors who only take one wedding a day need booking in the first two weeks.

When should you send invitations for a wedding in 3 months?

Around six weeks before, which is within the usual six-to-eight-week window for a local wedding. Send a digital save-the-date as soon as the venue is booked.

What is the hardest part of a 3-month timeline?

Finding a venue and key vendors free on your date. Weekday, Sunday and off-season dates are much easier to get at short notice.

Do we need a wedding planner for a 3-month timeline?

Not necessarily, but a planner or venue coordinator with local contacts can save time. See how much a wedding planner costs.
