With 242 years of tradition behind it, the Fourth of July is one of America’s most cherished holidays. It's when we celebrate our nation's mythology with a day off, a backyard barbecue, and plenty of fireworks. But with all that history, you'd be forgiven if you didn't know quite everything about July 4. So 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 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 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). Early printed copies of the Declaration were signed by John Hancock and secretary Charles Thomson 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 to follow at a later date. Hancock (boldly) signed his name again on the updated version.

So if you want to sound like a history buff at your family's barbecue this year, point out that we're celebrating the adoption of the Declaration, not the signing of it.

2. THE FIRST 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; the King’s coat of arms was used as kindling for a bonfire in Philadelphia; 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. Once you get past the mock funerals and rioting of 1776, modern Independence Day celebrations have stuck pretty close to the traditions started in 1777.

3. EATING SALMON ON THE FOURTH IS A TRADITION IN NEW ENGLAND.

The tradition of eating salmon on the Fourth of July began in New England as kind of a coincidence. It just so happened that during the middle of the summer, salmon was in abundance in rivers throughout the region, so it was a common sight on tables at the time. It eventually got lumped in to 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 HOLIDAY.

Massachusetts recognized the Fourth of July as an official holiday on July 3, 1781, making it the first state to do so. It wasn't until June 28, 1870 that Congress decided to start designating federal holidays [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 would take 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 Fourth of July was even recognized 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 2017 will be its 232nd entry. 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.

6. AND THE SHORTEST PARADE IS IN APTOS, CALIFORNIA.

From the oldest to the shortest, 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 the American Pyrotechnics Association, around 15,000 fireworks displays will take place 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 at around $2.5 million.

8. WE'LL EAT AN OBSCENE AMOUNT OF HOT DOGS.

Around 150 million, to be more specific—that's how many hot dogs will be consumed by Americans on the Fourth of July. 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 2016, 70 of those dogs were scarfed down by Joey Chestnut, who won the annual Nathan’s Hot Dog Eating Competition for the ninth time.

9. AND WE'LL SPEND BILLIONS ON FOOD.

Americans will spend big on food and drinks this Fourth. Big to the tune of around $7.1 billion when all is said and done, according to the National Retail Federation. This includes food and other cookout expenses, averaging out to about $73 per person participating in a barbecue, outdoor cookout or picnic.

Then comes the booze. The Beer Institute estimates that Americans will spend around $1 billion on beer for their Fourth celebrations, and more than $450 million on wine.

10. THREE PRESIDENTS HAVE DIED, AND ONE WAS BORN, ON THE FOURTH.

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.

Autumn Equinox: The Science Behind the First Day of Fall

On September 22, the Sun will shine directly over the equator—the midpoint of the Earth. (For 2018, this moment will happen at 9:54 p.m. ET.) The whole world will thus experience a day and night of equal length. In the Northern Hemisphere, we call this the autumn equinox. It marks the first day of fall. Around the world, people are marking the day with ceremonies, some of them ancient (and some less so).

You might be wondering two things: 1. Why on almost every other day of the year (the vernal equinox being the other exception) do different parts of the world have days and nights of differing length? 2. What do they call the day in the Southern Hemisphere?

A DAY AT THE BEACH

The answer to each of these questions resides in the Earth's axial tilt. The easiest way to imagine that tilt is to think about tanning on the beach. (Stay with me here.) If you lay on your stomach, your back gets blasted by the Sun. You don't wait 30 minutes then flop over and call it a day. Rather, as you tan, every once in a while, you shift positions a little. Maybe you lay a bit more on one side. Maybe you lift a shoulder, move a leg a little. Why? Because you want the Sun to shine directly on a different part of you. You want an even tan.

It might seem a little silly when you think about it. The Sun is a giant fusion reactor 93 million miles away. Solar radiation is hitting your entire back and arms and legs and so on whether or not you adjust your shoulder just so. But you adjust, and it really does improve your tan, and you know this instinctively.

The Earth works a lot like that, except it's operating by physics, not instinct. If there were no tilt, only one line of latitude would ever receive the most direct blast of sunlight: the equator. As the Earth revolved around the Sun, the planet would be bathed in sunlight, but it would only be the equator that would always get the most direct hit (and the darkest tan). But the Earth does have a tilt. Shove a pole through the planet with one end sticking out the North Pole and one end sticking out the South, and angle the whole thing by 23.5 degrees. That's the grade of Earth's tilt.

Now spin our little skewered Earth and place it in orbit around the Sun. At various points in the orbit, the Sun will shine directly on different latitudes. It will shine directly on the equator twice in a complete orbit—the fall and spring equinoxes—and at various points in the year, the most direct blast of sunlight will slide up or down. The highest latitude receiving direct sunlight is called the Tropic of Cancer. The lowest point is the Tropic of Capricorn. The poles, you will note, are snow white. They have, if you will, a terrible tan—and that's because they never receive solar radiation from a directly overhead Sun (even during the long polar summer, when the Sun never sinks below the horizon).

WHEN DO THE SEASONS CHANGE?

The seasons have nothing to do with the Earth's distance from the Sun. Axial tilt is the reason for the seasons. The Sun is directly over the Tropic of Cancer (66.5 degrees latitude in the Northern Hemisphere) on June 21 or 22. When that occurs, the Northern Hemisphere is in the summer solstice. The days grow long and hot. As the year elapses, the days slowly get shorter and cooler as summer gives way to autumn. On September 21 or 22, the Sun's direct light has reached the equator. Days and night reach parity, and because the Sun is hitting the whole world head-on, every latitude experiences this simultaneously.

On December 21 or 22, the Sun is directly over the Tropic of Capricorn in the Southern Hemisphere, meaning the Northern Hemisphere is receiving the least sunlight it will get all year. The Northern Hemisphere is therefore in winter solstice. Our days are short and nights are long. Parity will again be reached on March 21 or 22, the vernal equinox for the Northern Hemisphere, and the whole process will repeat itself.

Now reverse all of this for the Southern Hemisphere. When we're at autumnal equinox, they're at vernal equinox. Happy first day of spring, Southern Hemisphere!

And welcome to fall, Northern Hemisphere! Enjoy this long day of sunlight, because dark days are ahead. You'll get less and less light until the winter solstice, and the days will grow colder. Take solace, though, in knowing that the whole world is experiencing the very same thing. Now it's the Southern Hemisphere's turn to get ready to spend some time at the beach.
