This year, the 314 Day season kicked off at the History Museum.

Yes, the local holiday has evolved into a full season, a week-long citywide celebration, with a packed itinerary of events, partnerships with businesses, organizations, and neighborhoods.

20 years in, 314 Day is proof that, while some trends may come and go, sometimes the simplest ideas, like loving your city, can have a lasting impact.

Co-founder Tatum Polk is celebrating the major milestone, while also looking ahead and beyond.

Year one to year 20, what's been the most surprising thing?

- That we thought we were the only ones that had this sort of love for the city, and we see it's much greater than us.

We embrace our flaws.

There's gonna be a joke about potholes in St.

Louis every time, but I think that we also just embrace the culture of being a melting pot.

- You're implementing this in other cities as well.

- Yeah, so other cities, City Chamber of Commerce and mayors have reached out to us and kinda want to know what the blueprint looks like.

And so actually the other guy who should be standing here with me is in Atlanta working on a 404 day.

And so we're excited about Atlanta having their day in Kansas City, Milwaukee, Nashville.

Everybody's kind of popping them off.

- And people need to love where they live to make it a great place.

- Absolutely.

If you don't have pride in your city, it's really hard to be a champion for it.

- 20 years from now, what do you hope to see?

- We're putting a time capsule together.

And so in 20 years, we look to open that time capsule.

What our favorite foods were, what the map of the city looked like from an aerial view, that sort of thing.

Yeah, you think in 20 years, White Castle, IMOs, I think so.

I think they'll be top of the list.

I think they'll survive.

I think they'll survive.

We'll see.

We'll see.

Will the Cardinals still be here?

Will the Blues still be good?

Right?

I think that's all of it.

The city soccer team will be 20 years in, 25 years in at that point.

Yeah.

So you can see real passion in the city and I think that that's the most important part for us.

Three, one, four.
