New Year’s Repost: Watching the Ball Drop — the Nautical Origins of a New Year’s Tradition

The USNO Millennium Time Ball

Tonight, millions will watch in person, online, or on television, as a jeweled ball drops in Times Square in New York City at exactly midnight to mark the arrival of the New Year, 2023. In recent years, the crowd in Times Square has been limited due to the pandemic, whereas this year, the pandemic restrictions have been lifted, so there should be a sizeable in-person turnout, despite forecasted rain this evening. 

Regardless of the turnout, the ball will drop at midnight. The six-ton Waterford crystal ball covered in 32,276 LED lights will not actually be “dropped” but lowered from a flag pole on the roof of One Times Square. In New York City, the tradition dates back to 1907. But where did the tradition of dropping a ball to mark the time originate?  

The practice dates back to 1829 and was related to helping sailors calculate their position at sea. Here is an updated repost.

When out of sight of land, a navigator can determine latitude, his position north or south on the globe,  by measuring the altitude of the sun using only a sextant and a nautical almanac.  To determine longitude, his position east or west, however, a navigator must compare the time of the locally observed noon with the time on his chronometer, usually set to the time in Greenwich, UK. The first chronometers rugged enough for use at sea were developed by John Harrison and others in the mid to late 18th century. By the 19th century, marine chronometers were adopted on naval ships and many merchant vessels.

But how could a navigator easily and precisely set his ship’s chronometers? To solve this problem, the Royal Navy’s Captain Robert Wauchope invented the time ball in 1829.  It was a large ball hoisted to the top of a pole on a building easily visible to ships in the harbor. The ball would be lowered at a precise time, usually noon or 1PM. When the navigators on ships in the local harbor saw the ball beginning to drop they could use it to set their chronometers to the exact time.

The first time ball was erected in Portsmouth in 1829, followed by a time ball at the Greenwich Observatory in 1833 and at the US Naval Observatory in Washington in 1845. Soon, time balls were installed in ports around the world.

In 1877, Western Union installed a time ball on its Manhattan headquarters, at Broadway and Dey Street. Its firing signal came from the Naval Observatory in Washington, via a dedicated telegraph line, which directed the ball to drop at noon New York time, or about 11:48 a.m. in D.C.  At a distance, the ball appeared to be a solid ball. It actually was made up of a dozen thin semicircles made of sheet copper, half of which were crescents. This allowed for minimal wind resistance when dropped.

On April 5, 1913, the Titanic Memorial Lighthouse was installed on top of the Seamen’s Church Institute and overlooked New York Harbor from Battery Park on the southern tip of Manhattan. From 1913 to 1967, a time ball on top of the lighthouse would drop down the pole to signal twelve noon to the ships in the harbor. In 1976, the Titanic Memorial Lighthouse was moved to the corner of Pearl and Fulton Streets, near the entrance to the South Street Seaport, in downtown Manhattan.

With the advent of radio time signals in the 1920s, the time balls became obsolete. Nevertheless, the time balls at the Greenwich Observatory and the US Naval Observatory continue to drop every day to give both locals and ships on the rivers a means of setting their watches. And, when the ball drops at midnight every year at Times Square, whether watched by many or a few, the bejeweled ball pays homage to Robert Wauchope’s invention, the time ball.

Happy New Year to all.
