The Fourth of July is packed with backyard barbecues and plenty of fireworks. With 244 years of tradition behind it, you'd be forgiven if you didn't know quite everything about America’s Independence Day. From the true story behind the signing of the Declaration of Independence to some staggering hot dog statistics, here are 10 things you might not know about the Fourth of July.

1. The Declaration of Independence wasn't signed on July 4 (or in July at all).

It might make for an iconic painting, but that famous image of all the Founding Fathers and Continental Congress huddled together, presenting the first draft of the Declaration of Independence for a July 4, 1776 signing isn't quite how things really went down. As famed historian David McCullough wrote, "No such scene, with all the delegates present, ever occurred at Philadelphia."

It's now generally accepted that the Declaration of Independence wasn't signed on the Fourth of July—that's just the day the document was formally dated, finalized, and adopted by the Continental Congress, which had officially voted for independence on July 2 (the day John Adams thought we should celebrate). John Hancock and Charles Thomson signed early printed copies of the Declaration to be given to military officers and various political committees, but the bulk of the other 54 men signed an official engrossed (finalized and in larger print) copy on August 2, with others following at a later date. Hancock (boldly) signed his name again on the updated version.

2. The first Fourth of July celebrations weren't much different than today's.

After years of pent-up frustration, the colonies let loose upon hearing the words of the Declaration of Independence in 1776. Military personnel and civilians in the Bowling Green section of Manhattan tore down a statue of King George III and later melted it into bullets [PDF]; Philadelphia patriots used the King's coat of arms as kindling for a bonfire; and in Savannah, Georgia, the citizens burnt the King in effigy and held a mock funeral for their royal foe.

Independence Day celebrations began to look a bit more familiar the following year, as the July 18, 1777 issue of the Virginia Gazette describes the July 4 celebration in Philadelphia:

"The evening was closed with the ringing of bells, and at night there was a grand exhibition of fireworks, which began and concluded with thirteen rockets on the commons, and the city was beautifully illuminated. Every thing was conducted with the greatest order and decorum, and the face of joy and gladness was universal."

There were even ships decked out in patriotic colors lining harbors and streamers littering city streets. Modern Independence Day celebrations have stuck pretty close to the traditions started in 1777.

3. Eating salmon on the Fourth of July is a tradition in New England.

The tradition of eating salmon on the Fourth of July essentially began in New England as a coincidence. During the middle of the summer, salmon was abundant in rivers throughout the region, so it was a common sight on tables at the time. The dish eventually got lumped into the Fourth and has stayed that way ever since, even with the decline of Atlantic salmon.

To serve salmon the traditional New England way, you'll have to pair it with some green peas. And if you're really striving for 18th-century authenticity, enjoy the whole meal with some turtle soup, like John and Abigail Adams supposedly did on the first Fourth of July. (You can still be a patriot without the soup, though.)

4. Massachusetts was the first state to recognize the Fourth of July.

Massachusetts recognized the Fourth of July as an official holiday on July 3, 1781, making it the first state to do so. Congress hadn’t even begun designating federal holidays until June 28, 1870 [PDF], with the first four being New Year's Day, Independence Day, Thanksgiving, and Christmas. This decreed that those days were holidays for federal employees.

However, there was a distinction. The Fourth was a holiday "within the District of Columbia" only. It took years of new legislation to expand the holiday to all federal employees.

5. The oldest annual Fourth of July celebration is held in Bristol, Rhode Island.

Eighty-five years before the government recognized Fourth of July as a federal holiday, one tradition began that continues to this day. Billed as "America's Oldest Fourth of July Celebration," the town of Bristol, Rhode Island, has been doing Independence Day right since 1785.

The festivities began just two years after the Revolutionary War ended, and 2020 will be its 235th anniversary. Over the years, the whole thing has expanded well beyond July 4; the town of 23,000 residents now begins to celebrate the United States on Flag Day, June 14, all the way through to the 2.5-mile July 4 parade. What began as a "patriotic exercise"—meaning church services—has morphed into a cavalcade of parades, live music, food, and other activities. In 2020, because of the coronavirus pandemic, the festivities will be scaled down and spread out throughout the summer.

6. The shortest Fourth of July parade is in Aptos, California.

The Fourth of July parade in Aptos, California, is just a hair over half a mile long. Taking up two city blocks, and measuring just .6 miles, this brief bit of patriotism features antique cars, decorated trucks, and plenty of walkers. Afterward, there's a Party in the Park, where folks can enjoy live music, food, and games.

7. There are around 15,000 Independence Day fireworks celebrations every year.

According to a 2017 American Pyrotechnics Association projection, around 15,000 fireworks displays occur for the Fourth of July holiday (even if some aren't exactly on July 4). Though pricing varies, most small towns spend anywhere from $8000–$15,000 for a fireworks display, with larger cities going into the millions, like the Boston Pops Fireworks Spectacular that averages more than $2 million.

8. Americans eat an obscene amount of hot dogs on the Fourth of July.

Americans consume about 150 million hot dogs while celebrating Independence Day. According to the National Hot Dog and Sausage Council, that amount of dogs can stretch from Washington D.C. to Los Angeles more than five times.

In 2018, Joey Chestnut scarfed down 74 of those franks, breaking his own world record. That year, Chestnut won the annual Nathan's Hot Dog Eating Competition for the eleventh time. He won again in 2019, noshing on 71 wieners.

9. Americans also spend billions on food to celebrate the Fourth of July.

In 2019, the the National Retail Federation predicted Americans would spend around $6.7 billion on tasty treats to celebrate the Fourth of July. This included food and other cookout expenses, averaging out to about $73 per person participating in a barbecue, outdoor cookout, or picnic.

Then comes the booze. According to the Beer Institute, "more beer is sold on and around the Fourth of July holiday than during any other time throughout the year." Generally, Americans will spend around $1 billion on beer for their Fourth celebrations, and more than $560 million on wine.

10. Three presidents have died, and one was born, on the Fourth of July.

You probably know that both Thomas Jefferson and John Adams died on July 4, 1826—50 years to the day after the Declaration of Independence was adopted. They're not the only presidents to have died on the Fourth, though; James Monroe—the nation's fifth president—died just a few years later on July 4, 1831.

Though the holiday might seem like it has it out for former presidents, there was one future leader born on Independence Day. The country's 30th Commander-in-Chief, Calvin Coolidge, was born on July 4, 1872.

5 Ways to Keep Your Dog Calm on the Fourth of July

The Fourth of July can be rough for dogs. Fireworks displays light up their senses with unfamiliar noises, flashes, and smells, and parties flood their homes with strange guests who may invade the rooms they usually have as private retreats. And when distressed dogs escape, howl, or thrash around the house, Independence Day can quickly become a nightmare for their owners, too. To minimize Fido's stress this holiday, we spoke to some dog experts to discover the best ways to keep your canine calm on the Fourth of July.

1. Exercise Your Dog

Anthony Newman, the dog whisperer who runs New York City's Calm Energy Dog Training, says that exercise is a great way to help your dog let off some nervous energy. "Whenever Fido is going to be neglected for an extended period of time, or around any stressful stimuli, it always helps to tire him out just before—and even during the night if you can," Newman says. "As the saying goes, a tired dog is a good dog! He'll be calmer, happier, and more peaceful."

2. Keep Your Dog Indoors

Dr. Stephanie Liff, head veterinarian at Pure Paws Veterinary Care, says the best place to keep your pet during a fireworks show is inside and away from the windows. "If the pet is very scared, an escape-proof crate or a sound-insulated room, such as an internal bathroom, may help the pet to feel more secure," Liff tells Mental Floss. "If you cannot keep your pet inside, make sure that the pet is prevented from escape (monitor all exits and tell guests to monitor your pet)."

3. Socialize Your Dog

While your dog may feel more secure in a room away from all the noise, Newman points out that keeping your dog isolated in another room for too long can be stressful for your pet. "Release his curiosity and let him in on the fun, to run around and play with both two-legged as well as four-legged guests," Newman says. "Then back to his obedient room, bed, car, crate, or spot. Rinse and repeat as needed throughout the night."

4. Take Control of Your Dog

According to Newman, the best way to keep your dog calm during the chaos of July 4th is to stay in charge. "If your dog winces, shivers, and runs away at loud noises, the last thing he wants is to feel like nobody else is looking out for him," Newman says. Don't let your dog run rampant around the house or follow him around trying to soothe him. Instead, Newman says it's important to "take control by attaching a super-light leash that you can grab and lead him whenever you need."

5. Explore Medicating Your Dog

In extreme cases of nervousness, Liff says that you should talk to your vet about medication to sedate your dog.
