The short answer: give a milestone birthday about three months. Lock in the date, budget and guest list first, then book the venue and the suppliers that sell out (catering, entertainment, photographer), send invitations six to eight weeks out, and spend the final fortnight confirming details and writing a simple run sheet.
A milestone birthday is part celebration, part reunion. People fly in, families mix with friends, and there’s usually a speech or two. Here’s a timeline that keeps it fun to plan.
12 weeks out: the big decisions
- Date and time. Check it against school holidays, long weekends and the birthday person’s key guests.
- Budget. Set a total and decide who is paying for what.
- Guest list. A rough number is enough for now, but it decides the venue.
- The vibe. Long dinner, cocktail party, garden afternoon or a big night with a DJ? Pick one clear idea.
- Surprise or not? Surprises need a trusted co-conspirator and a cover story.
10 weeks out: venue and key bookings
- Shortlist venues that fit the numbers and the vibe, then book one. Ask about minimum spend, finishing time, music and access for set-up.
- Planning it at home? Think about toilets, power, parking, neighbours and a wet-weather plan.
- Book catering (if the venue doesn’t provide it), entertainment and a photographer.
8 weeks out: invitations
- Send invitations or a save-the-date with an RSVP deadline about three weeks before the party.
- Ask for dietary and accessibility requirements in the RSVP.
- Share travel tips for out-of-town guests.
6 weeks out: styling and details
- Choose a simple look: a colour palette, florals, a few statement pieces and good lighting go a long way.
- Order the cake.
- Plan the moments: arrival, speeches, cake, first dance or a surprise.
- Gather photos if you are planning a slideshow.
4 weeks out: confirm the menu and drinks
- Finalise food and drinks, including great non-alcoholic options.
- Line up speakers and give them a time limit.
- Arrange transport home, especially for a late finish.
2 weeks out: final numbers and run sheet
- Chase outstanding RSVPs and confirm final numbers with the venue and caterer.
- Write a one-page run sheet: supplier arrival times, speeches, cake, last drinks and finish time.
- Send the run sheet and a contact list to every supplier.
The week of the party
- Reconfirm every supplier by phone or message.
- Check the weather if any part is outdoors, and make the wet-weather call at an agreed time.
- Pack a small kit: tape, scissors, lighter, spare batteries, phone chargers, first-aid basics.
- Hand the run sheet to someone who isn’t the guest of honour.
The one rule that mattersMake sure the birthday person and their closest family don’t spend the night running it. Give the jobs to someone else.
