quick answer
Start planning a kid’s birthday party 6–8 weeks ahead. The short version:
- 8 weeks out: set the budget, guest count and date.
- 6 weeks: book the venue or entertainer.
- 4 weeks: send invitations with an RSVP date.
- 2 weeks: order the cake, favors and decorations.
- 1 week: confirm RSVPs and the venue.
- Party day: arrive early, enjoy it, and take photos.
Planning a kid’s birthday party gets stressful when everything happens in the last week. Spread it out and it’s easy. Here’s the week-by-week timeline we use, with a party-day checklist at the end.

8 weeks before: set the basics
- Set your budget. Our party cost calculator gives you a total in about a minute.
- Decide on the guest count. A classic rule is the child’s age plus one, but a whole-class party is common from kindergarten to 2nd grade.
- Pick 2–3 possible dates. Check school calendars, holidays and sports schedules.
- Choose home or venue. Venues cost more but handle setup and cleanup. Home parties cost less but take more work.
6 weeks before: book the venue or entertainer
Popular weekend slots go first, so book now. On Go Greatest, you can filter by party type, kids’ ages and town, and see prices before you call.
- Ask what’s included: party room, host, food, paper goods, cleanup.
- Ask about the deposit and the cancellation policy.
- Ask how many kids the package covers and the price per extra child.
- Pick a theme your kid is excited about. Browse party themes for ideas.
4 weeks before: send invitations
- Send invitations 3–4 weeks before the party.
- Set the RSVP date one week before the party.
- Include the start and end time, address, parking tips and what kids should wear.
- Add an optional gift wish list link so guests don’t buy duplicates.
3 weeks before: plan food and activities
- Plan one main food (pizza is the classic), snacks, drinks and cake.
- Ask guests about food allergies on the RSVP.
- Plan 2–3 activities for a home party, or ask the venue what they run.
- Pick a playlist.
2 weeks before: order the extras
- Order the cake or cupcakes.
- Order decorations, balloons and paper goods.
- Buy favors: one small item per kid is plenty.
- Buy the birthday kid’s outfit if it’s a big deal to them.
1 week before: confirm everything
- Follow up with anyone who hasn’t replied.
- Confirm the final headcount with the venue.
- Confirm time and address with any entertainers or vendors.
- Make a simple day-of schedule.
Party day checklist
- Cake, candles and a lighter
- Plates, napkins and a knife for the cake
- Favors or goody bags
- Phone charged for photos
- A bag for gifts and a pen for noting who gave what
- Wipes, paper towels and a trash bag
After the party
- Send thank-you notes within 2 weeks.
- Leave a review for your venue or entertainer; it helps other parents.
