Make it a weekend getaway
What could be more relaxing than a weekend with your closest friends and family? Rent a cabin or pitch tents in a beautiful locale—a flower-filled meadow, a red-rock desert, or a lake nestled in the mountains.
Welcome guests with an under-the-stars reception, complete with delicious appetizers and perhaps even a signature cocktail. Then, end the night with a decadent dinner party and a night of dancing with your favorite songs from the past four decades.
When it comes to accommodations, each guest may have their own preferences. As such, provide your guests with a selection of sleeping options—on-site glamping tents for lovers of camping and nearby hotels or holiday rentals for the less seasoned outdoor enthusiasts.
After a night of sleeping under the stars, say farewells to guests the next day with a village fête send-off—an elaborate festival complete with food, games, and entertainment. It’ll certainly be a weekend to reminisce on for birthdays to come.

Join forces and plan a family bash
Plan a traditional family weekend all of your invitees can enjoy, no matter their age. Set out for the countryside with all the aunts, uncles, and cousins you can gather to celebrate the next decade of life. In the afternoon, set up activities suitable for cross-generational fun, whether it’s a badminton tournament or a treasure hunt that pits youngsters against their elders in a friendly competition for a prestigious prize—the winner gets to choose dessert.
Pick a meadow with plenty of space to picnic or pitch tents. Or, find a park pavilion with enough space to host family and friends. Once the youngsters are asleep, kick things up a notch for an evening of fun—drinks, games, and reminiscing about the last four decades.

Plan a surprise ʼ90s bash
Are you on party planning duty for a loved one turning the big 4-0? Call all your best partiers and dancers for an epic surprise birthday bash that will transport your celebrant back to the days of acid-wash denim, butterfly clips, and boy bands.
Remind your guests of any party must-haves before attending, whether it’s a costume or a vaccination card. Then, get the celebration started with a DJ to play all the top hits from the ʼ90s (a Spotify playlist will work just as well) for a peppy soundtrack to dance the night away.
Provide your guests with a selection of ʼ90s-era fruity cocktails like Cosmopolitans, Apppletinis, and Strawberry Daiquiris. We also strongly suggest ordering pizza for a much-needed refuel session.
Make safety, laughter, dancing, and the birthday star’s smile your top priority of the night. A ʼ90s party is the perfect gateway to a new feel-good decade. Plus, we have the perfect invite. You can throw an ʼ80s bash, too!

Oh, Schitt. He’s 40!
Let your friends know it would give you no greater joy than to spend the evening with them to celebrate your 40th birthday! Pitch a “Schitt’s Creek” dress code—grandiose wigs and hats for the Moiras, graphic sweaters and high-top Converse for the Davids, and chic dresses and ditzy hand flips for the Alexises. You can even compete in an “Ew, David” impression contest!
If your guests have no idea what you’re talking about when you reference the Rosebud Motel, encourage them to binge the series before the birthday bash to catch them up on the hit riches-to-rags sitcom.

Rent out a hotel
Go big with a hotel extravaganza! Many hotels allow guests to book a block of rooms (typically nine or more) at a discounted price for birthday celebrations. The hotel will most likely offer a slew of amenities and activities, from rounds of golf to spa days. Depending on the location, the hotel may even offer wine tasting events.
Before setting your guests loose, be sure to clarify which events are included in the hotel stay, and which aren’t. Non-hosted events, like the ones listed above, can usually be paid directly through the hotel during the event. Hosted events, such as pool-side cabanas, casual dinners, and farewell brunches, are also a great way to bond with your guests and celebrate the new decade!

Host a big dinner in the big city
If you’re lucky enough to live a train ride away from the Big Apple, invite guests to a classy night on the town with a “New York Glam” themed birthday dinner. Ask guests to tune into their inner Carrie Bradshaw or Samantha Jones with a dress code that screams New York chic, then take to the streets for a night of decadent treats, a broadway show, and a nightcap before bedtime.
Even those who are Midwest or West-coast bound can participate in the fun with a big-city-themed soirée, complete with Manhattan cocktails, a streaming of broadway-hit “Hamilton,” and an Italian dinner for the ages (and ageless).

Throw a chalet birthday
If you love skiing, head to the slopes for a weekend packed with powder, moguls, more than a couple of cold ones at your après party.
There’s plenty of activities on and off the mountain to celebrate in grand winter fashion—from mountain top dining to spa treatments at the lodge. You can even hold a snowman-making competition to see which one of your guests can best portray the birthday boy or girl in a flurry.
Wondering how to beckon your closest family and friends to the slopes? We’ve got an invitation for that.

Hold a game night (or day)
Celebrate your 40s with a game night alongside a few of your closest friends and family.
Whether you’re figuring out whodunnit with Clue or partaking in fast-dealing property grabs with Monopoly, a game night is an amusing way to celebrate your big day intimately. If you’re looking for a more active celebration, consider competing in a laser tag competition, a paint gun war, or a bowling tournament. Or you can take to the sand for a fierce game of beach volleyball.
No matter your game of choice, make sure it’s one your entire guest list can get involved with and enjoy.

Recruit friends and family to help give back
Your 40th birthday can also be a way to give back and make a difference within your community. Bring along friends and family to your favorite neighborhood charity or nonprofit to offer a few dozen helping hands to those in need. Most likely, there will be a food bank, an animal shelter, or a homeless shelter nearby that needs extra assistance. If you’re not keen on participating in the day-to-day activities of the charity, consider donating food or clothes instead!
At the end of the day, what matters most is not the success you’ve accumulated over the years, but the people you’ve uplifted along the way.

Belated birthday? Celebrate with a 40.5 birthday party
If your 40th birthday coincided with the lockdowns of 2020 and you were unable to celebrate with family and friends, consider throwing a 40.5 birthday party now, belatedly.
If you’re feeling whimsical, go with an “Alice in Wonderland” theme complete with a Mad Hatter’s tea party and a 40/5 mad hatter hat for the birthday boy or girl. You can also go with a more casual theme, such as a backyard get-together or a movie night with close friends.
To make sure your guests don’t miss the shindig, plan on sending party save the date cards to their homes.
40th birthday invitation wording
In addition to choosing 40th birthday celebration ideas, invitations are perhaps the most important aspect of party planning. They let your guests know when and where your party will take place, as well as any additional details such as party theme, dress code, or gift guides. As such, you’ll want to make sure your invitations stand out in design and wording. Luckily, we’re here to help.
