How Denver Will Celebrate America’s 250th: Events and Flag Etiquette

July 4, 2026, marks a moment most of us will only experience once in our lifetimes: America’s 250th birthday. The semiquincentennial (try saying that five times fast) is shaping up to be one of the biggest celebrations in our nation’s history, and Denver is gearing up to make it count.

But here’s the thing. As exciting as the parades and fireworks will be, there’s another side to this celebration that often gets overlooked: showing proper respect for the American flag. Whether you’re flying Old Glory outside your home or business, or you’re planning to wave one at a community event, knowing the right way to display and handle the flag matters.

At AC Flag and Banner, we’ve been helping Denver residents and businesses find quality flags for over 21 years. We’ve seen a lot of celebrations come and go, but this one feels different. It’s bigger. And we want to make sure you’re ready for it, both with the right flag and the knowledge to display it with pride.

What Is America’s Semiquincentennial?

Let’s break down that big word. “Semiquincentennial” simply means 250th anniversary. On July 4, 2026, the United States will celebrate 250 years since the signing of the Declaration of Independence. That’s a quarter of a millennium since our founding fathers put pen to paper and changed the course of history.

For Colorado, this celebration carries extra weight. Our state is marking its own 150th anniversary (that’s a sesquicentennial, if you want another vocabulary word). Colorado became the 38th state on August 1, 1876, earning it the nickname “The Centennial State” because it joined the Union during America’s 100th birthday year. So in 2026, we’re celebrating two major milestones at once.

This kind of dual celebration doesn’t happen often. The last time America marked a milestone this significant was the bicentennial in 1976. If you were around for that, you probably remember the red, white, and blue everything. The 250th promises to be even bigger, with events planned across the country and right here in the Denver metro area.

The official national celebration is being coordinated through America250, while Colorado’s events fall under the Am250CO150 initiative. Both organizations are working together to create a year of programming that honors our past while looking toward our future.

Major Denver Events for the 250th Anniversary

Denver and the surrounding Colorado region have a packed calendar of events leading up to and throughout 2026. Here’s what you can look forward to.

Parades and Public Gatherings

While specific parade routes and dates are still being finalized, the Am250CO150.org website is serving as the central hub for community event submissions. Cities and towns across the state are encouraged to host their own celebrations, which means we’ll likely see everything from small neighborhood gatherings to large-scale downtown parades.

The state has also launched an ambitious “Stories in the Sky” drone show series. The first show debuted at a CU Buffaloes game in September 2025, and these aerial displays will continue throughout 2026, culminating in December. It’s a modern twist on traditional fireworks that’s worth checking out.

Concerts and Cultural Celebrations

History Buff Day, set for January 24, 2026, is a great example of the family-friendly programming planned for the celebration. This event features scavenger hunts and activities designed to get kids (and adults) excited about American history.

Cultural celebrations will tie into the various exhibits and programs happening at venues throughout Denver. Expect community dinners, musical performances, and events that highlight the diverse stories that make up our national identity.

Historical Exhibits and Educational Programs

History Colorado Center is going all out for the 250th. Their flagship exhibit, The Moments that Made US, features 50 artifacts spanning 800 years of American history. We’re talking about pieces like Paul Revere’s spoon and Jackie Robinson’s bat. These aren’t replicas. They’re the real deal.

Another exhibit worth your time is 38th Star: Colorado Becomes the Centennial State, which dives deep into our state’s unique place in American history. Both exhibits are currently on view, so you don’t have to wait until 2026 to start celebrating.

Coming in January 2026, Mountains Majesty: On the Summit with John Fielder will showcase stunning photography of Colorado’s landscapes. Other programs include:

• How the Word is Passed lecture (January 21, 2026)
• Preservation for Posterity (January 29, 2026)
• Tours & Treks: Olympic City USA (February 5, 2026)
• Low Sensory Morning events for visitors who prefer a quieter experience

These educational programs offer something for everyone, whether you’re a history buff or just looking to learn more about where we came from.

Proper Flag Etiquette for the Celebration

With all this celebration comes a lot of flag waving. And while enthusiasm is great, it’s important to display the American flag correctly. The U.S. Flag Code provides guidelines that help us show proper respect for our national symbol. Here’s what you need to know.

How to Display the American Flag

The basics matter. When displaying the flag outdoors, fly it from sunrise to sunset. If you want to keep it up at night, make sure it’s properly illuminated. Nobody wants their flag sitting in the dark.

When hoisting the flag, do it briskly. When lowering it, take your time and lower it ceremoniously. There’s a rhythm to it that reflects the respect we have for what the flag represents.

For homes, attach your flag to a staff that projects horizontally from the building. On freestanding poles, fly the flag at the peak (unless it’s at half-staff by executive order). When displayed with other flags, the American flag should be positioned with the union (the blue field with stars) uppermost and to the observer’s left, which is the flag’s own right.

If you’re displaying multiple flags on adjacent staffs, the American flag should be hoisted first and lowered last. It should also be flown at the same height or higher than other flags.

Common Flag Etiquette Mistakes to Avoid

We see these mistakes more often than you’d think:

• Letting the flag touch the ground. This is probably the most common error. When raising, lowering, or storing your flag, make sure it never touches the ground, floor, or water.
• Using the flag as clothing or drapery. Wearing an actual flag as a cape or using it as a tablecloth isn’t appropriate. Flag-themed clothing is different and perfectly fine.
• Carrying the flag flat or horizontally. The flag should always be carried aloft and free, not stretched flat.
• Keeping a worn-out flag on display. When your flag becomes faded, torn, or otherwise no longer suitable for display, it’s time to retire it. The proper way to do this is by burning. Many local organizations, including the American Legion and VFW, hold flag retirement ceremonies.

At AC Flag and Banner, we often help customers find replacement flags when their current ones have seen better days. A fresh, high-quality flag makes a real difference, especially during a celebration as significant as the 250th.

How to Get Involved in Denver’s 250th Festivities

There’s no shortage of ways to participate in the 250th celebration, whether you’re an individual looking to join the fun or a business wanting to show some patriotic spirit.

First, check out the Am250CO150.org calendar regularly. New events are being added, and you can even submit your own community event for inclusion. Hosting a neighborhood block party? A historical reenactment? A flag-raising ceremony? They want to hear about it.

Volunteering is another great option. America Gives, a nationwide volunteer initiative tied to the 250th, is encouraging Americans to give back to their communities. Check their website for opportunities in the Denver area.

History Colorado offers memberships and tickets to their exhibits and programs. If you want to dive deeper into the educational side of the celebration, this is the place to start. Their events range from lectures to hands-on activities for families.

For businesses, this is an excellent time to update your flag display. A quality American flag flying outside your storefront or office sends a message about your values. It also creates a sense of community during a year when everyone will be paying attention to these symbols.

You might also consider hosting your own event. Community dinners, educational programs, and local celebrations are all encouraged. The more people participate, the more memorable this anniversary will be.

Conclusion

America’s 250th anniversary is a once-in-a-generation event. Denver and Colorado are preparing celebrations that honor our history while bringing communities together. From world-class exhibits at History Colorado Center to drone shows lighting up the night sky, there’s something for everyone.

But beyond the events, there’s a simpler way to participate: fly your flag, and fly it right. Proper flag etiquette isn’t about rigid rules. It’s about showing respect for the symbol that represents all of us.
