Yes, a week is enough. Send text invitations tonight, keep it to about 12 guests at home or a park, buy the cake and food ready-made, and skip anything that has to be booked. A 2-hour party with one main game, pizza, cupcakes and a simple craft is a full, happy party.
Here is the countdown, one short list per day. Most days take under an hour. If you'd rather not track the rest by hand, Festidy's free birthday party planner turns your date and guest count into a dated checklist and a shopping list.
The week at a glance
| Day | Main job | Time it takes |
|---|---|---|
| 7 days out | Date, place, guest list, text invitations | 1 hour |
| 6 days out | Menu, shopping list, cake order | 30 minutes |
| 5 days out | Pick games and one craft from what you have | 30 minutes |
| 4 days out | Chase replies, set the headcount, buy decor | 45 minutes |
| 3 days out | The big shop | 1 to 2 hours |
| 2 days out | Favors, playlist, run sheet, helpers | 1 hour |
| 1 day out | Clean the party rooms, set up, chill drinks | 2 to 3 hours |
| Party day | Pick up, set out, have fun | 2 hours plus setup |
The normal kids' birthday party timeline starts 6 to 8 weeks out. This plan squeezes the essentials into seven days and drops the rest.
7 days out: decide and invite
Make four decisions in one sitting, then send the invitations before bed.
- Date and time. A 2-hour party is the sweet spot for most ages, 90 minutes for ages 1 to 3. Afternoons from 2 to 4 work well for school-age kids.
- Place. Home is easiest on short notice. A park works too, but first-come spots and no backup room add risk. Pick an indoor fallback before you commit.
- Guest list. For young kids, a handy rule of thumb is their age plus one. Count grown-ups too: with Festidy's usual mix, 12 guests is about 7 kids and 5 adults.
- Theme, if any. Pick one your child already loves and you already own props for. A color can be the theme.
Text invitations are fine for a last-minute party. They arrive instantly and parents reply faster. Ask for answers within three days instead of the usual week before.
Invitation line: "Short notice, big fun! Olivia turns 6 on Saturday, 2 to 4 pm, at our house. Can you come? Please reply by Wednesday and tell us about any food allergies."
A Festidy invitation goes out as a link you can text, with an RSVP page where guests reply without an account and note allergies. Replies update the headcount and the shopping amounts as they arrive.
No time to design anything? Every theme comes with ready designs, like these. Tap one, add your details and text the link:
6 days out: menu, shopping list, cake
Write the menu around pizza or another one-call main. For 12 guests that's 4 large pizzas: 2 slices per kid, 3 per adult, 8 slices per pizza. The pizza guide has other headcounts.
What to buy for 12 guests:
| What | How many | Why |
|---|---|---|
| Large pizzas | 4 | 2 slices a kid, 3 a grown-up, 8 a pizza |
| Plates | 24 | 30 cups and 36 napkins too |
| Kids' drinks | 14 | Juice boxes, pouches or lemonade: 1 a kid an hour |
| Grown-ups' drinks | 15 | Soda, sparkling water, beer or wine: 2 each the first hour, then 1 |
| Waters (8 oz) | 19 | 8 oz a kid an hour, half that for grown-ups; or about 1.5 gallons in a dispenser |
| lb of ice | 24 | 2 lb a guest; double it on a hot day |
| Cups of fruit or veg | 12 | Plus about 21 oz of chips |
| Favors | 9 | One per child, plus 2 spares |
| Cake servings | 12 | an 8-inch round or a dozen cupcakes: 7 kids, 5 adults |
Call a grocery bakery today about the cake. Many can do a simple decorated sheet cake or a tray of cupcakes on short notice, but ask what they need and when. If the answer is no, plan on store cupcakes plus a pack of number candles.
5 days out: games and one craft from the house
Shop your closets before the store. You need one main game for 0:30 and one calm craft for the end.
- Main game ideas with no supplies to buy: freeze dance, a five-clue treasure hunt, sharks and minnows in the yard, a couch-cushion obstacle course.
- Easy crafts: decorate a paper crown, sticker-and-marker bags that become the favor bag, paper plate masks.
Plan one spare 10-minute game in case the main game runs short. The games by age guide has more ideas sorted by age band.
4 days out: chase replies and buy decor
Text anyone who hasn't replied: "Just checking if [child] can make it Saturday, so I get enough pizza." A direct, friendly question is easy to answer.
Set your headcount tonight, even with a few unknowns. Round up by one or two kids.
Buy decor in one trip to a dollar store or party store. Pick two colors and stop there:
- One balloon bunch or a dozen balloons for the door and the table
- A plastic tablecloth in one color
- A "Happy Birthday" banner
Latex balloons and broken balloon pieces are a choking risk for children under 8, so pick up any that pop right away (CPSC).
3 days out: the big shop
One cart, one list. Buy everything that keeps:
- Plates, cups and napkins: 2 plates, 2.5 cups and 3 napkins per guest
- Drinks: adults 2 for the first hour and 1 each hour after, kids 1 juice box or pouch an hour, plus water (8 oz a kid an hour)
- Snacks, fruit and veggies for a tray (or buy ready-made trays for the day before)
- Favors: one per child plus 2 spares for siblings, about $2 to $5 each
- Craft supplies you didn't find at home
- Candles, a lighter and a cake knife
Order pizza delivery now for the party day, timed to arrive 15 minutes before snacks at 1:00. Some shops take scheduled orders; if yours doesn't, set a phone reminder.
2 days out: favors, music and helpers
Stuff the favor bags at the kitchen table while you watch TV. Make a 2-hour playlist. Print or write the run of show and stick it on the fridge.
Ask one or two adults to help with specific jobs: one runs the main game, one handles pizza and drinks. Specific asks get a yes faster than "can you help out?"
1 day out: set up the night before
Clean only the rooms guests will use: the entry, the party room, the kitchen and one bathroom. Close every other door. Nobody at a 6-year-old's party inspects the guest room.
- Hang the banner and the balloons, or leave balloons for the morning so they look full.
- Set out the tablecloth, plates and a trash can with a spare bag in the bottom.
- Chill the drinks. Buy ice, about 2 lb per guest (double it on a hot day), or plan to grab it in the morning.
- Lay out the game supplies and the craft in labeled bins.
- Charge the speaker and your phone.
Party day: a 2-hour run of show
Pick up the cake in the morning and fruit trays if you didn't make them. Set the food table 30 minutes before guests arrive.
- Final setup and safety checkSetup crew gets food, activities, and the entrance ready.
- Arrivals and free playKid wrangler greets kids and keeps an eye on arrivals.
- Main game or entertainerEntertainment lead runs the planned game or entertainer.

For a 2 pm start: free play at 2:00, the main game at 2:30, pizza at 3:00, cake at 3:20, the craft, favors and goodbyes at 3:35, done at 4:00.
Store-bought shortcuts that look planned
| Instead of | Buy | About |
|---|---|---|
| A custom-decorated cake | A grocery bakery sheet cake or 24 cupcakes | $20 to $45 |

| Cooking a main | 4 large pizzas for 12 guests | $50 to $80 |
| Printed invitations | A text with an RSVP link | Free |

At the low end, this lands near Festidy's Simple budget for 12 guests, about $180. The Standard level, about $360, adds one hired activity and nicer extras. The budget post shows where to trim.
What to skip with one week's notice
- Entertainers and rentals. Popular ones book up early, especially on weekends. One call is worth it; a week of calls isn't.
- A custom cake. Custom bakers often need two or three weeks. A bakery sheet cake with a few toys on top reads as themed.
- Paper invitations. The post takes days you don't have.
- Matching everything. One color pair beats a half-finished theme.
- A long guest list. A shorter list means faster replies and one pizza order.
- Deep cleaning. Clean the party rooms and close the other doors.
FAQ
Is one week enough notice for guests?
It's short, so expect a few families to have plans already. Text invitations help, because parents see them right away, and a weekend afternoon gives the most families a chance to come.
Is it okay to send party invitations by text?
Yes, especially for a last-minute party. Include the date, time, address, a reply-by date and a line asking about food allergies.
What's the bare minimum for a kids' birthday party?
Friends, a cake with candles, one game and something to eat. Pizza, cupcakes, freeze dance and a small favor per child cover all of it in two hours.
