The New Year's ball was based on a navigational tool

A New York fireworks ban necessitated a new way to ring in the New Year

In 1906, the city banned fireworks displays, forcing the Times Square celebration to find a new centerpiece. The Times commissioned Jacob Starr, a Ukrainian immigrant who worked for Strauss Signs, to develop an ornament. He returned with the now-iconic New Year’s ball.

Early timekeeping tools included sundials, water clocks, and astrolabes

Astrolabes also provided a person's latitude based on the height of the stars in the sky, thus aiding in navigation. Incense and candle clocks relied on the constant burning rate of fire to track the passage of time based on premarked locations with equal-interval spacing.

The Times Square New Year's ball has been redesigned 8 times

The first iteration was made of iron and wood, weighing in at 700 pounds. The 2025 version is made of 5,280 crystals and 32,256 LED lights and weighs a whopping 12,350 pounds.

Railroads and long-distance communication led to the development of time zones, with Greenwich established as the prime meridian—the longitude of 0 degrees—due to British advancements in star mapping and navigation.

From the Greek for 'star taker,' the astrolabe allowed individuals to tell time and determine their latitude based on the position of the sun or other stars, as well as calculate the height of objects.

The history of the New Year's misunderstanding in England

In the mid-18th century, the legal system in England operated under the understanding that the New Year began March 25. However, the widespread custom remained a Jan. 1 celebration as the public had been practicing for years. Read along to discover the practical issues this discrepancy caused and how the English legal system ended up yielding to public belief.

The Antikythera mechanism: The oldest-known analog computer

A device now considered the world's oldest computer was pulled from a shipwreck more than 120 years ago. Known as the "Antikythera Mechanism," it is now believed to have allowed precise tracking of astronomical positions, and its sophistication overturned understanding of Ancient Greek capabilities.

The hour originated from an ancient Egyptian astronomical system

The movements of astronomical objects, measured in a day and a year, form the foundation of our sense of time. The Egyptians divided each day and night into 12 time eras, using arbitrarily selected stars as references rather than movements of specific celestial objects.

The solar noon clock outside Rhodes Hall at Cornell is named after Bill Nye

In addition to displaying the analog time, the clock's face features an indicator disc that illuminates, even on cloudy days, whenever the sun reaches its highest point in the sky. Nye developed the initial apparatus designs, which were later co-engineered and built by Cornell staff and students.

A 1908 toy visualizes how the sun never set on the British Empire

Researchers uncovered an early-1900s children’s toy that romanticized the British Empire: a rotating world map showing where the sun shone on Britain’s far-flung territories. The interactive device also served as an advertisement for "The Children’s Encyclopedia."

Before alarm clocks, people relied more heavily on their circadian rhythms, humans hired to wake them, and on tools such as candle clocks that dropped pins in metal trays at roughly set intervals.

Ned Nye instilled an interest in timekeeping and sundials in Bill Nye

While a prisoner of war for four years during World War II, the Japanese military confiscated Ned's watch, so he built sundials to keep track of time. Ned would later research and write a book on sundials and be honored with a lifetime membership to the North American Sundial Society.

Watch 5 decades of Times Square ball drops

Dick Clark started hosting his “New Year’s Rockin’ Eve” show in 1972, which has become an annual television staple. This compilation includes five decades' worth of ball drops, allowing you to watch how the tradition subtly evolved.

In the 1910s, sailors on a US Navy ship started using the term 'happy hour' in reference to their leisure hours

The leisure activities sailors were treated to during the ship's long voyages included boxing tournaments and dancing—but unlike the happy hours we know today, they likely didn’t involve alcohol. This article includes more information about happy hour’s origin story.

Designed in 1937 by Harvard graduate student Howard H. Aiken, the 'Harvard Calculator' was used by the US Navy to solve advanced physics problems.

Researchers once thought Stonehenge functioned as a precise astronomical computer

In the 1960s, scientists used early computers to analyze the stone layout at Stonehenge, arguing it could predict eclipses and other celestial events. This BBC Sky at Night Magazine piece explains how the theory arose—and why scholars now doubt it.

Ancient Greek astronomer Hipparchus created accurate maps of the night sky way ahead of his time, with coordinates sometimes within a single degree of modern values.

Guy Lombardo first played ‘Auld Lang Syne’ on New Year’s Eve because of a cigar sponsorship

The bandleader was booked to play a New Year’s Eve concert live on CBS radio program called the Robert Burns Panatela Show, named after its sponsor, a cigar brand. Lombardo, noting the cigar's name, decided “Auld Lang Syne,” penned by the poet Robert Burns, would be both a fitting tribute and, thematically, a great way to enter a new year.

The American colonies recognized New Year’s Eve in March until 1752

England followed the Julian calendar, established by Julius Caesar, which had an inaccurate method of calculating leap years. Because of that, New Year’s Day eventually slipped into the spring and was linked with the Christian festival of the Annunciation, which was on March 25. That date carried over to the American colonies, which didn’t change the first day of the new year until 1752, after England adopted the newer Gregorian calendar.

The team responsible for the first interplanetary sundials included Bill Nye

While reviewing designs for instruments to be carried by future Mars rovers, Nye suggested adapting the function of a calibration tool, which would be used by the Spirit and Opportunity rovers to help calibrate the brightness and color of their panoramic cameras on the Martian surface.

The Times Square New Year's celebration originated as a party for The New York Times

The paper moved to the area, originally called Longacre Square, in 1904 and lobbied the city to rename it after the publication. The paper’s publisher, Alfred Ochs, threw a massive all-day party on New Year’s Eve to celebrate the opening of the paper’s headquarters, establishing the location as a destination for the holiday.

What the stars once meant to ordinary people

The stars were a crucial aid for ordinary human beings in premodern societies, acting as regular timekeeping phenomena and celestial navigators. Today, light pollution and modern technology have rendered the stars a mere aesthetic delight for most of us, but their significance in history remains. Watch this brief video to learn how premodern humans used the stars for navigation, mathematics, and more.

New Year's Eve celebrations date back to ancient Babylon

Rather than celebrating in winter, the Babylonians honored the vernal equinox, a day in late March with equal amounts of darkness and light that signaled the start of a new year. They celebrated with Akitu, an 11-day festival.

View depictions of world maps throughout history

The first map to use latitude and longitude positions was created by Ptolemy in 150 CE, over 700 years after the oldest known world map, the Imago Mundi, was made with a Babylonian clay tablet. The Spanish crown created a secret master map from hundreds of sailors’ reports.

A 2,000-year history of alarm clocks

Clocks have revolutionized the way we live, structuring our days into abstract, regular units and providing quantification for those who are chronically late. The alarm clock was the next obvious step: clocks which not only tell you the time but...

The unexpected origin story of the snow globe

In 1900, a Vienna tradesman named Erwin Perzy I was attempting to invent an inexpensive way to improve light amplification in hospital operating rooms. After experimenting with a glass globe filled with water, the idea for the snow globe struck. Industrious as well as inventive, Perzy eventually turned his idea into a successful business. Read the full article to learn how the invention grew to become recognized globally.

The earliest earthquake-detection device—the seismoscope—was invented in China in 132 CE and featured eight ball-wielding dragons facing different directions.

Anglo-Saxons toasted the new year

The lord of a manor toasted his subjects at the start of a new year with the Old English phrase “waes hael,” which roughly translates to “be well.” “Wassailing” involved traveling from house to house, singing songs, and continuing to drink, a practice that eventually influenced caroling.

Astronomers inferred Neptune's existence through mathematics while attempting to explain irregularities in Uranus' orbit, but Neptune had been directly observed 234 years earlier by Galileo.

Why atoms are used to keep track of time and define the meaning of a second

Small variations in the production of human-made devices, such as mechanical watches and pendulums, make them unreliable for the ultraprecise timekeeping required by modern technology, including financial transaction timestamping and GPS. Because atoms obey fundamental laws of nature and never wear out, their light emissions when energized provide a consistent timekeeping signal.

Throughout the 1980s, the Times Square ball was a giant apple

From 1981 to 1988, the sparkling ball was replaced by a “big apple” to promote the city’s “I Love New York” tourism campaign. This broadcast is from the apple’s first year, where one announcer proclaims, “It’s great! It’s beautiful!”

The tradition of drinking Champagne on New Year's is believed to come from ancient Rome

Julius Caesar might not have had sparkling wine, but when the Romans created the now-standard calendar that begins on Jan. 1, they celebrated with a toast. The tradition spread throughout Europe and then the colonies, and so when Champagne became the drink of choice for special occasions, it was only natural that it became the standard New Year’s Eve sip.

How did Polynesian wayfinders navigate the Pacific Ocean?

Ancient Polynesian navigators used the sun, moon, stars, clouds, currents, and more to sail the seas. People of Southeast Asia began their voyages to the region now known as Polynesia in roughly 1500 BCE. They would settle a vast area of 15 million square miles, including hundreds of islands, moving from islands due to overpopulation or war. Such voyages dwindled in 1300 CE as societies became more rooted.

The best New Year’s Eve drops

There’s more out there than the Times Square ball drop. This list ranks the best of the rest, including the Great Pinecone Drop in Arizona, the Lebanon Bologna Drop in Pennsylvania, and the Pickle Drop in North Carolina.

One of the first mechanical calculators—the Pascaline—was built in the 1640s by French mathematician Blaise Pascal to help his father, who worked as a tax collector.

Calibrate to the U.S. government's official clock, synchronized to the atomic standard

The site displays the current time across all American time zones—corrected for network delay—and shows whether your device's clock has drifted. Computer clocks rely on quartz crystals that drift slightly with temperature and age, requiring alignment with atomic clocks (which are so stable that seconds are defined by them).

More than 2,000 years ago, a hand-powered model of the solar system called the Antikythera mechanism—the oldest example of an analog computer—could predict solar eclipses.

Some people smash Champagne bottles on ships for good luck

Long before Champagne existed, people performed good-luck rituals before setting sail. But since animal sacrifice is generally frowned upon these days, a new tradition developed before a ship’s maiden voyage: smashing a bottle of Champagne against the hull.

Halley's comet is named after the astronomer who predicted its next appearance

Edmund Halley realized that historical accounts of a celestial object passing in the night sky in 1531 and 1607 referred to the same object he observed in 1682. By applying Newtonian mechanics to his observational data, he calculated its orbit and accurately predicted its return in 1758.

Many New Year's Eve traditions came from German immigrants

While it’s hard to trace the origins of many New Year’s traditions, many of the norms for American New Year’s Eve celebrations come from German immigrants, who significantly influenced American culture in the 1800s. Below is an excerpt from an 1863 New York Times article describing a German New Year’s celebration.

The simple melody in 'Auld Lang Syne' has led to the song’s repurposing

In addition to becoming a standard tune to ring in the new year, the song has been reworked as a Dutch soccer anthem, a Japanese standard, and the South Korean national anthem. A significant part of its widespread use is that it has no copyright limitations. It helps, too, that it's simple melody is easy for even the most amateur singers to tackle.

Aristotle discovered that Earth was spherical by observing the round shadow it cast on the moon during lunar eclipses and by noting that different constellations were visible from different latitudes.
