Most baby shower games are about the host. Diaper-changing relay races, baby-food taste tests, the one where everyone smells melted candy bars in diapers — they're filler. They keep the room moving between mimosas and gifts.
The guess-the-due-date game is different. It's the only baby shower game that produces something the baby actually keeps.
Here's how to play it well, the variations worth knowing, and why the printable version is missing the most important part.
The basic rules
Each guest writes down their guess for the baby's date and time of birth. The person whose guess is closest to the actual birth wins.
That's it. The whole game.
It works because it taps into something real: babies don't arrive on their due date. Only about 4% of babies are born on the calculated due date. The rest land in a wide window — usually two weeks earlier or two weeks later. So everyone has a roughly equal shot, and "winning" feels earned rather than luck.
It also stays alive past the shower. The game ends when the baby is born — which means weeks of group-chat banter, predictions, friendly trash talk. A diaper relay race is over in five minutes. A guess-the-due-date game runs for a month.
Variations worth using
Date only — simplest version. Each guest picks a date on a calendar. Closest date wins. Good for casual showers.
Date + time — adds a tiebreaker. Each guest picks date and time of day. Closest by combined difference wins. Better when you have 20+ guests and want to avoid a tie.
Date + time + weight + length — full prediction card. Each guest fills out date, time, baby's weight, and baby's length. Scoring is points-based: closest date = 10 points, closest weight = 5 points, etc. Most points wins. This is the deluxe version and the one people remember.
The fund version — each guess comes with a contribution. The fund goes to the baby. The closest guesser gets recognition (and sometimes a small prize). This is the version that actually matters, and we'll come back to it.
The printable problem
Search "guess the due date calendar" and you'll find a few hundred Etsy printables, Pinterest templates, and PDF downloads. They all look great on the surface — a cute calendar with the due date marked, space for guests to write their names on the day they pick, a small "Closest guess wins!" line at the bottom.
The problem with the printable version isn't aesthetic. It's that the printable doesn't do the thing. It records guesses. It doesn't collect contributions. It doesn't notify guests when the baby arrives. It doesn't track anything after the shower ends.
What actually happens with a printable:
- The shower happens. Everyone writes a name on a square.
- The printable goes into a closet.
- Three months later, the baby is born.
- The host means to track down the closest guess and announce the winner.
- The host has a newborn and never does that.
- The game ends with no winner, no follow-up, and no fund.
It's not anyone's fault. It's just that paper can't do the job once the shower is over.
The digital version (what's missing from every printable)
A digital guess-the-due-date game does what the printable can't:
- Lives online, so guests who couldn't attend can still play
- Tracks every guess in one place, so you don't have to find the paper
- Sends a notification when the baby is born, so the winner is announced automatically
- Collects contributions alongside each guess, so the game is also a fund
- Generates a memory — a record of who guessed what, that you can show your kid later
That last one is underrated. Years from now, your child will be able to see that Aunt Theresa guessed April 4 and Uncle Marcus guessed April 18 and a college friend guessed February 28 because she thought you'd "definitely go early." It becomes part of the story of their arrival.
How the contribution piece works
The guess-the-due-date game becomes a real baby shower platform when each guess is tied to a contribution. The mechanics are simple:
- You create a digital calendar and set your due date
- You share a link with friends and family (in-person and remote)
- Each guest picks a date, optionally adds a time/weight/length prediction, and contributes whatever amount feels right
- All contributions go directly to your account
- When the baby is born, the system calculates the closest guess and announces the winner automatically
The contribution range matters. Most families set it at $20-$100 per guess, with some guests choosing higher amounts for "extra" predictions (people often want to spread their bets across a few dates). That's how a baby shower of 30 friends turns into a $1,500-$3,000 fund.
What you do with the fund is up to you. We'd argue strongly for investing it — a $2,000 fund collected at birth becomes nearly $8,000 by your child's 20th birthday at a 7% annual return, without any further contributions. But the platform doesn't dictate where it goes.
When to skip the game
If your shower is under 8 people, the guess-the-due-date game falls flat — there aren't enough guesses to make it interesting. Stick to the conversation.
If you've already chosen a specific charity or fund that wouldn't accept guess-based contributions (some 529 plans, for example, have specific gift mechanisms that don't play well with this), it's worth checking compatibility before setting it up.
If you genuinely can't predict the due date because the pregnancy is complicated or scheduled (a c-section on a known date, for example), the game loses its magic. Use a different shower game.
How to actually set it up
The fastest path: create a First Step calendar. It's a free birth date prediction calendar with the contribution piece built in. You set your due date, customize the design, and share a link. Guests guess and contribute through their browsers or phones. When the baby is born, you mark the actual date and the system handles the rest.
You can also do it manually if you want — a Google Sheet for guesses, Venmo or PayPal for contributions, your own follow-up to announce the winner. It works. It's just more work than most people want during the third trimester.
Either way, the game is the same. The only question is whether you want it to do something at the end.
