2. Make the number 39 special and celebrate with Queen

If you are a Queen fan, 39 is a pretty exciting number! ‘39 is Queen’s 39th song. Mercury is the planet .39 astronomical units away from the sun. And Freddy Mercury is a legend. So what better age for a Queen-themed party?!

Outfit the party with tons of Queen crest decor, play ‘39 (and your other Queen favorites) on repeat, and challenge your guests to come dressed as Freddy Mercury (give them some heads up though — they’ll need time to grow out their mustaches!).

3. Host an epic murder mystery birthday party

Have you heard of the children’s book series 39 Clues? It’s a mystery series that requires the protagonists to solve 39 clues! Make your own 39 Clues game on your 39th birthday with a murder mystery party with 39 clues or a scavenger hunt with 39 clues!

4. Make memories by spending time at Pier 39

If you live near San Francisco or plan on visiting for your 39th, Pier 39 is the perfect spot to celebrate your big day — especially if you book a jaw-dropping venue in the area.

If San Francisco isn’t in the cards for your celebration, that doesn’t mean you can’t party like you’re on Pier 39. Hire a few street performers for your party, have a photo backdrop of the Golden Gate Bridge for pictures, and maybe even hire a caricature artist to draw all your bday guests!

5. Take a road trip across America and rack up 39 state visits

How many states have you visited? If it’s less than 39, rent an RV and hit the road until you get to 39! Taking some time off to travel the U.S. with family is a fantastic way to ring in your 39th year.

This is also a fun tradition to start with the family to make sure every year is an adventure — commit to visiting a new state every year!

6. Flashback to the 80s for a year-you-were-born celebration

Take your party back in time and celebrate like it’s still the 1980s! After all, if you’re celebrating your 39th birthday in 2024 or 2025, that means you were born in 1985 or 1986. Ask your guests to come wearing their best neon get-up, blast some Michael Jackson, and prepare yourself for one heck of an epic 80s throwback party!

Here are our favorite 80s party ideas to get you started. And if you want to incorporate a photoshoot into your 39th birthday ideas, then we have a ton of retro 80s photoshoot ideas for you, too!

Birthdays don’t have rules — celebrate being whatever age you feel. Miss being 25? Guess it’s time to invite your friends to your 25th birthday party! Your birthday, your rules. Plus, you don’t look a day over 22, anyway!

12. Show gratitude for how far you’ve come

Did you know that in Japanese, the number 39 is a number that means gratitude? That’s because the number 3 is pronounced “san” and the number 9 is pronounced “kyuu”. Put it together, and you have what sounds like “thank you” in English!

When we reach the age of 39, it’s easy to be grateful for how far we’ve come and for all the people who have helped us get this far. Incorporate these warm and fuzzy feelings and spend a day near your 39th birthday celebrating what you’re most thankful for.
