Why is Election Day not a holiday? 11 curious facts about elections

Image: Element5 Digital

The election system is full of rules that may seem unusual at first glance, but most of them have deep roots in American history. What may seem odd today can often be explained by the practical needs of the past: These rules were shaped by politics, geography, and early compromises that still influence how our voting system works. Understanding these 11 oddities of American elections makes for an interesting history lesson, and it also makes the system much easier to follow.

1
Why are elections held on a Tuesday?

Election Day is always on a Tuesday because of 1800s rural life . Most Americans were farmers who needed a full day to travel to polling places, often by horse. Sunday was reserved for church, and Wednesday was typically market day.

Tuesday became the most practical option: travel on Monday, vote on Tuesday, return on Wednesday. November was chosen because the harvest season had ended, but winter had not yet made travel difficult.

2
Why do voters register in advance to participate?

Voter registration exists because the U.S. has no single national voter list . Since elections are run locally, authorities need a system to confirm identity, residency, and eligibility before Election Day.

The practice expanded in the 1800s as cities grew, helping manage large populations and reduce fraud. Today, it remains a key administrative step in a decentralized system.

3
Why does the Electoral College decide presidential elections?

The Electoral College was created as a compromise between letting Congress choose the president and allowing a direct popular vote, which proved logistically challenging at the time . The founders were concerned about balancing power and limiting centralized control.

It also gave smaller states more influence against larger states with more population, and reflected the challenges of communication in the 1700s. The system remains as part of the original constitutional design.

4
Does each state run its own election system?

Image: Elliott Stallion

The Constitution gives states the authority to manage elections , reflecting the country’s federal structure. The founders wanted states to retain power rather than create a single national system.

This allowed flexibility based on local conditions like geography and population. Today, it explains why voting rules and procedures differ widely across states. These differences range from voter registration policies to the types of documents required for voting to whether prison inmates are allowed to vote, among many other variations.

5
How are party candidates determined?

Image: Ernie Journeys

Primaries were introduced in the early 1900s to reduce the influence of party insiders . Before that, candidates were often chosen behind closed doors by political leaders.

The reform movement aimed to give voters more control. Primaries shifted decision-making power from party elites to the public, making the process more democratic.

6
What is early voting?

Image: Manny Becerra

Early voting developed to address the limitations of a single Election Day . As work schedules became less flexible, states began offering additional in-person voting days.

These days, most states offer early voting, with examples like Minnesota, South Dakota, or Virginia, extending that period to over 40 days prior to the official election. This change helps reduce long lines and increase participation. It reflects an effort to adapt an old system to modern time constraints. And, judging by the 60% of votes being cast before Election Day, it works.

7
What about mail-in voting?

Image: Tiffany Tertipes

Mail-in voting began during the Civil War, allowing soldiers to vote while away from home . Over time, it expanded to include civilians who could not easily reach polling places.

Its broader use today reflects convenience and accessibility, especially in a large country where distance and mobility can be barriers to in-person voting.

8
What can a ballot include?

F ederal, state, and local referendums are often combined into a single election . This means that American ballots can include several voting points.

Studies indicate that this approach saves money by avoiding multiple referendums and increases participation by attracting individuals interested in voting on those topics. It also allows voters to decide on laws and policies directly through referendums and ballot measures.

9
Who are the poll workers?

Image: Arnaud Jaegers

Poll workers are typically local citizens because elections are run at the community level. Instead of a national workforce, local governments recruit and train temporary staff.

Most poll workers are community members who apply directly through their local election office. Also, in many states, local chapters of political parties submit lists of recommended workers to election boards. Officials often prioritize these nominees to meet legal requirements for partisan balance.

10
Why is Election Day not a federal holiday?

Image: Janelle Hiroshige

Election Day was never made a federal holiday because early lawmakers assumed rural voters had flexible schedules. Travel time, not work obligations, was the main concern .

Today, this decision is often debated. Modern work patterns make weekday voting less convenient, leading to calls for reform or expanded voting options.

11
Why do results take so long?

Image: Markus Winkler

Final results can take time because ballots must be carefully verified before counting . This includes checking signatures, eligibility, and processing mail-in and provisional votes.

While early results are reported quickly, official certification happens later. The delay reflects a priority on accuracy and legitimacy over speed.

The secrets of the greenback

Dollar bills are green for this reason

Image: Pepi Stojanovski

The U.S. dollar is one of the most powerful and recognizable currencies in the world, but its physical form is unique for many other reasons . From its composition to its symbols, dollar bills and coins are carefully designed to combine history, security, and convenience. Let’s explore our national currency!

1
What are bills made of?

Image: Viacheslav Bublyk

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2
What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3
American leaders

Image: Lukasz Radziejewski

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4
A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5
Uniformity

Image: Avinash Kumar

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6
Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7
A $100,000 bill?

Image: The original uploader was Durova at English Wikipedia., Public domain, via Wikimedia Commons

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8
No numbers

Image: Quilia

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9
Liberty for all (the coins)

Image: Money Knack

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10
A global currency

Image: Logan Voss

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

Stories carved by the Colorado River

The missing pieces of the Grand Canyon: 10 incredible facts

Image: jesus esteban

The Grand Canyon is bigger than Rhode Island. It's deeper than four Empire State Buildings stacked end to end. Its rocks are older than dinosaurs. But those stats alone don’t quite capture its immensity — and are hardly the most shocking. There are nuclear shelters, hidden villages, and billion-year mysteries involved. Read on to learn 10 lesser-known facts about the Grand Canyon.

1
There's an unexplained billion-year gap

Image: John Graybosch

Look closely at the canyon walls, and you'll notice something strange: a clean, sharp line where ancient rock simply stops, and a much younger layer begins directly above it.

This geological puzzle is called the "Great Unconformity," and it represents over a billion years of rock layers that are simply absent , as though that stretch of time never happened. In some spots, rock dated 1.8 billion years old sits directly beneath rock that is only 520 million years old. Where did the missing billion years go?

The leading theory involves the violent breakup of an ancient supercontinent, but scientists are still piecing it together.

2
During the Cold War, it hid a nuclear fallout shelter

During the Cuban Missile Crisis in 1962, the U.S. government converted part of the Grand Canyon Caverns into a fallout shelter. This dry cave system, more than 200 feet underground, was stocked with enough food and water to sustain 2,000 people. Naturally, it was never occupied, and the supplies were never used.

The caverns have since been transformed into a tourist attraction, with organized tours winding through the same underground chambers that were once intended as a refuge from nuclear war. You can even book a night's stay there.

3
The Federal Aviation Administration was founded after a crash over the canyon

Image: Alexandre Henry Alves

In 1956, two commercial passenger planes collided in midair over the eastern Grand Canyon, killing all 128 people on board both crafts. Rescue teams struggled to reach the wreckage deep inside the canyon, and the extreme heat of the crash had caused the planes' aluminum to fuse with the bedrock. There were no survivors.

The disaster exposed a terrifying truth: the U.S. air traffic control system was dangerously outdated, relying on pilots' visual estimates and rough guesswork from controllers , with no way to separate fast-moving aircraft from slow ones, or instrument-flying planes from those navigating by sight. Congress responded by passing legislation that created both the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

4
A hoax suggested that an Egyptian civilization had lived there

Image: abdurrohman dzar

In 1909, the Arizona Gazette reported that an explorer named G. E. Kinkaid had discovered a vast underground citadel inside the canyon, filled with artifacts linked to ancient Egyptian civilization. He even claimed the expedition had been funded by the Smithsonian.

This story described hieroglyphics on the walls, mummies in the chambers, and relics pointing to a direct connection with the Egypt of the pharaohs. It was incredibly detailed, and it was, of course, a hoax. No evidence for any of Kinkaid's claims ever surfaced.

5
Fewer than 100 people have ever hiked its full length

Image: Abhishek Navlakha

Among the few people who have completed the through-hike of the Grand Canyon is Jen Hogan, the first woman to accomplish it, finishing her journey in 2021–2022.

It’s a full 800-mile length below the rim. The route involves extreme heat, flash floods, near-impassable areas, and stretches with no water or trail whatsoever. Around 60 or 70 people have reportedly accomplished it. This makes it one of the most exclusive feats on Earth.

6
The Grand Canyon's rocks predate dinosaurs entirely

Image: MARIOLA GROBELSKA

Visitors scanning the canyon walls for fossils are often surprised to learn they won't find any dinosaur bones here. The rock layers of the Grand Canyon are simply older than dinosaurs. This fact alone can be shocking: staring at its walls means staring at marine fossils from as far back as 1.2 billion years ago. Some of its caves hold the remains of ancient mammals. The canyon is a window into a world that existed long before the dinosaurs, when the land that is now Arizona lay beneath a shallow sea.

7
The park is bigger than Rhode Island

Image: AussieActive

Numbers alone rarely capture the Grand Canyon's scale, so here's a different approach. Rhode Island covers about 1,214 square miles, and the Grand Canyon National Park spans 1,904 square miles.

The canyon's depth exceeds four Empire State Buildings (which is 1,454 feet) stacked on top of one another. That’s 6,093 feet at its deepest point.

8
But it's not the deepest canyon on Earth

Image: Naeemphotographer2

For all its grandeur, the Grand Canyon does not hold the depth record. Pictured above, the Yarlung Tsangpo Grand Canyon in Tibet, China, plunges to 17,567 feet, which is nearly three times deeper. Carved by the Yarlung Tsangpo River as it cuts through the eastern Himalayas, that canyon is so remote and extreme that it remained largely uncharted until the late 20th century.

9
It is home to a pink rattlesnake found nowhere else on Earth

Image: Alexander Wong

The Grand Canyon Pink Rattlesnake has a pinkish-red coloring that matches the canyon's own distinctive rock walls so closely that it's nearly invisible. It is found nowhere else in the world. Officially classified as Crotalus oreganus abyssus , it has darker diamond-shaped markings along its back that deepen the camouflage further.

10
There's a village at the bottom: Supai Village

Image: joojoob27

For over 1,000 years, the remote village of Supai has been home to the Havasupai Tribe, the People of the Blue-Green Waters. It is located an eight-mile hike from the rim, but sits roughly 3,000 feet deep inside the Grand Canyon.

The U.S. Department of Agriculture has called it the most remote community in the contiguous United States, and it has no automobiles and no road access. The only ways in are on foot, by mule, or by helicopter. It is also the only place in the United States where the postal service still delivers mail by mule train.
