12 Month Wedding Planning Checklist: Every Task and Who Owns It

This 12 month wedding planning checklist puts every task on the page, in order, with a name next to it: you as a couple, your point person, family, the wedding party or a vendor. Most checklists stop at the task, and that is where things slip, because nobody knows whose job it is. If you have less time, skip to the 6 month or 3 month fast track near the end.

Key takeaways

  • Book the venue and date first. Most other bookings depend on them.
  • Every task gets one owner. Shared tasks are the ones that get dropped.
  • Pick a point person early: a planner, a day-of coordinator or a calm friend who runs the day.
  • Write every deposit and final payment date down the day you sign.
  • Short on time? The 6 month and 3 month fast tracks keep the same order and squeeze the steps.

Who Owns What: The Five Owners

Every task below ends with an owner in brackets. Owning a task means making sure it happens, not doing every part of it alone.

The five owners in this checklist
OwnerWho it isUsually owns
CoupleThe two of youBudget, guest list, contracts, big decisions
Point personA planner, day-of coordinator or trusted friendTimeline, vendor check-ins, the day itself
FamilyParents or anyone helping pay or hostTheir guest list, rehearsal dinner, hotel block questions
Wedding partyYour attendantsTheir outfits, showers, helping on the day
VendorAnyone you've hiredWhat their contract says they deliver

If one of you is better with spreadsheets and the other is better on the phone, split the Couple tasks that way. Write the initials of the partner who leads each one.

6 Month Wedding Planning Checklist: The Fast Track

Six months is enough if you're flexible on the date. Friday, Sunday and off-season dates often have more openings. The order stays the same; you just do more each month.

3 Month Wedding Planning Checklist

Three months works best with fewer vendors. A restaurant, a hotel or a venue that includes food, drinks, tables and staff turns five bookings into one.

Keep the Checklist and the Money Together

Most tasks in the first six months end with a deposit. The Wedding Budget & Payment Planner has a page per vendor for the quote, the deposit, the final payment date and the hidden fees, so the money side keeps pace with this list.

Frequently asked questions

What should you do 12 months before the wedding?

Set the budget, agree on your top 3 priorities, draft the guest list, pick possible dates and choose a point person. Then start touring venues.

What is the first thing to book for a wedding?

The venue and date. The photographer, caterer, officiant and most other vendors need both before they can confirm.

Can you plan a wedding in 6 months?

Yes, especially with a flexible date. Use the 6 month fast track above and look at Friday, Sunday or off-season dates.

When should wedding invitations go out?

Commonly 6 to 8 weeks before the wedding, with the RSVP date about a month before. Send them earlier if many guests need to travel.

Who should do which wedding planning tasks?

Give every task one owner: the couple, a point person, family, the wedding party or a vendor. Write the name next to the task so nothing is shared by everyone and done by no one.
