About Time in Kentucky

Louisville's Leap Across the Line

Kentucky is one of a handful of states split between two time zones, with most of the commonwealth running on Eastern time while a western band, including Paducah and the Jackson Purchase region, keeps Central time instead. The boundary has not stayed fixed for the state's entire history. Louisville itself once ran on Central time, only switching permanently to Eastern time on July 23, 1961, a change made to bring the state's largest city into closer alignment with the business hours of East Coast markets and media. The area around the small city of Monticello, in Wayne County, made a similar switch decades later, moving from Central to Eastern time on October 29, 2000, after residents found that most of their shopping, schooling, and commerce already ran toward Eastern time communities to the east.

The resulting boundary does not track a straight line, and it produces a genuinely unusual quirk: roughly 30 percent of the land area now sitting in the Eastern time zone actually lies farther west than parts of the state still on Central time, a legacy of the boundary bending around county lines and local economic ties rather than following longitude in any consistent way. The practical result is a version of Kentucky where crossing certain county borders means gaining or losing an hour without traveling especially far, a fact of daily life for commuters, sports broadcasters, and families with relatives split across the line.

The Clock That Raced Itself at Noon

For much of the late twentieth century, downtown Louisville was home to one of the more eccentric public clocks in the country. The Louisville Clock, commonly called the Derby Clock, was a 40 foot tall ornamental timepiece designed by local sculptor Barney Bright, commissioned in 1970 and formally dedicated on Fourth Street in December 1976. Built in the shape of an oversized wind up toy, it featured an elevated five lane track ringed by eight columns, and at noon each day a bugle call would set off a miniature horse race among carved figures representing George Rogers Clark, Daniel Boone, Thomas Jefferson, King Louis XVI of France, and the steamboat Belle of Louisville, while mechanized figures of other notable Louisvillians, including former president Zachary Taylor and filmmaker D.W. Griffith, watched from a Victorian style gazebo above.

The clock's mechanical ambition proved to be its undoing. Plagued by recurring breakdowns and expensive upkeep, it was dismantled and moved into storage in 1993, later restored through years of volunteer effort at Bowman Field and returned to public display in Theater Square around 2012, only to break down again and be dismantled a second time in 2015. It remains in storage in Louisville today, a beloved but currently silent landmark whose noon horse race, once a genuine daily ritual for downtown workers and visitors, has not run in years.

The Fastest Two Minutes in Sports

The Kentucky Derby has earned its nickname as the most exciting two minutes in sports quite literally: since the race distance was shortened to one and a quarter miles in 1896, only two horses in well over a century of Derby history have ever finished the course in under two minutes. The record belongs to Secretariat, who covered the distance in 1 minute, 59 and two fifths seconds on May 5, 1973, a time that has stood unbroken through every Derby run since and remains one of the most famous marks in American sports. Secretariat ran the race's final quarter mile faster than any of the quarters before it, an acceleration pattern that still strikes race analysts as remarkable nearly a full lifetime later.

Only one other horse has managed to slip under the two minute mark since: Monarchos, ridden by jockey Jorge Chavez, finished the 2001 Derby in a computer timed 1 minute, 59.97 seconds, edging under the barrier by the narrowest of margins. Every other Derby winner across more than 150 runnings, dating back to Aristides, who won the very first Derby in 1875 in 2 minutes, 37 and three quarters seconds over the original one and a half mile distance, has needed at least two full minutes to reach the finish line, a reminder of just how exceptional those two performances remain.
