Whether you're planning a milestone birthday, a conference, a wedding or a garden party, the underlying rhythm is the same. Big, slow decisions belong at the start; small, fast ones belong at the end. The mistake almost everyone makes is leaving slow decisions late — chasing a venue or a caterer three months out, when the good ones were booked long ago. This timeline keeps the order right. Adjust the distances to your own event: a large wedding or conference may want twelve months, an intimate dinner just six weeks. The sequence holds regardless.

How to use this timeline

Read it once end to end so you can see the whole shape, then work backwards from your date. Put every stage in your calendar as a milestone — "venue booked", "invitations out", "final numbers" — and you'll always know whether you're ahead or behind. Pair it with two companions: a budget that holds so you know what you can commit to at each stage, and a record of which suppliers you've booked and what's still outstanding.

6+ months out: the foundations

This is where the decisions that everything else depends on get made. Take your time here, because rushing the foundations is what causes the panic later.

• Set the date and the rough budget. Everything flows from these two numbers. Hold the date loosely until the venue is confirmed.
• Decide the guest count and the type of event. Numbers drive venue size, catering and cost more than anything else.
• Book the venue. The single most time-sensitive booking. Popular venues — and Saturdays in summer especially — go a year or more ahead. Secure this first and the rest becomes possible.
• Book the headline suppliers. Caterer, photographer, and anyone in genuine demand. The best book up early; waiting costs you the people you actually want.
• Send a save-the-date if guests need notice to travel or take time off.

If you do only one thing six months out, book the venue. Almost every other decision waits politely until you have a place and a date.

3 months out: lock in the detail

The frame is up; now you furnish it. This stage is about turning broad bookings into specific, confirmed details.

• Send the formal invitations with a clear RSVP deadline a few weeks before the day. Track replies as they arrive rather than at the end.
• Finalise the menu and drinks with your caterer, including dietary requirements and service style.
• Confirm the styling and any hire — furniture, lighting, linen, décor. Our styling basics can help you brief this with confidence.
• Sort the running order. Sketch how the day flows, hour by hour, even loosely. It reveals gaps you'd otherwise miss.
• Book the practical extras — transport, accommodation blocks, signage, and any permits or licences the event needs.
• Review the budget. By now real quotes have replaced estimates. Reconcile, and make sure your contingency is still intact.

1 month out: confirm everything

One month out, the work shifts from booking to confirming. Nothing new should be starting; everything booked should be pinned down.

• Chase outstanding RSVPs and settle on a working headcount.
• Reconfirm every supplier — date, arrival time, what they're providing, and the final cost. Put it in writing.
• Build the detailed schedule — a proper timeline for the day with arrival times, key moments, and who's responsible for what.
• Pay outstanding balances as they fall due, and tick each off your tracker.
• Plan the seating or layout if your event needs one, allowing for late changes.
• Brief your helpers. Decide who's doing what on the day, and make sure they know in advance — not on the morning.

The final week: tie off loose ends

The final week should feel like confirming, not creating. If you've followed the timeline, there are no big jobs left — only the satisfying business of tying everything off.

• Give final numbers to the caterer and venue by their deadline.
• Do one last supplier sweep — a short call or message to each, confirming arrival time, access details, and a contact number for the day.
• Print or prepare what's needed — schedules, place cards, signage, contact lists.
• Confirm setup and breakdown windows with the venue so everyone knows when they can get in and must be out.
• Pack your kit. Pull together everything that needs to travel to the venue and the things that always get forgotten.
• Check the weather if any part of the event is outdoors, and trigger your wet-weather plan early rather than late.

The day itself: hand it over

On the day, the planning is done — your job changes from organiser to host. The single most valuable thing you can do is delegate, so that you are present at your own event rather than running it. Hand over the schedule and the supplier contact list to a coordinator, your venue, or a capable friend, and let them be the point of contact for any wrinkles.

• Brief your point person first thing, with the schedule and every supplier's number.
• Arrive early enough to oversee setup without rushing, then step back.
• Let small things go. Almost nothing that goes slightly wrong on the day is noticed by guests. Your calm sets the tone for everyone.
• Confirm pack-down — who's clearing, what's being collected, and when the venue needs to be empty.

A timeline doesn't make the work disappear, but it does make it manageable — each task arriving when there's time to do it well. Follow the order, keep your milestones in the calendar, and you'll reach the day having enjoyed the planning rather than survived it. When the final week comes, our on-the-day checklist takes over from here, right down to the emergency kit and the pack-down list.
