About Time in Missouri

The Meeting in St. Louis That Started It All

Eleven years before American railroads formally adopted standard time, the organization that would eventually make that decision was born in St. Louis. In 1872, a group of railroad superintendents met in the city to coordinate summer passenger schedules, and rather than disband afterward, they formed a permanent body called the Time-Table Convention.

That organization evolved into the General Time Convention, the same body that gathered at Chicago's Grand Pacific Hotel on October 11, 1883, to adopt William F. Allen's plan for five continental time zones. The formal vote and the historic Day of Two Noons both happened in Chicago, but the institutional seed that made the decision possible was planted in St. Louis a full decade earlier, when nobody in the room yet imagined they were founding the body that would end fifty different local times in the United States.

A Legislature Arguing With Itself

Missouri's lawmakers have spent recent years pulling in opposite directions on the same question. In 2024, Representative Van Schoiack introduced HB 1607, which would have taken Missouri out of Daylight Saving Time entirely and kept the state on permanent Standard Time starting that November. The following year brought HB 701, pursuing a similar standard time direction.

Then, in April 2026, the chamber flipped its position entirely. Representative Jamie Gragg of Ozark sponsored HB 1758, the Daylight Saving as New Standard Time Pact, which asked for exactly the opposite outcome, permanent Daylight Saving Time rather than permanent Standard Time. It passed the Missouri House by a lopsided 107 to 31 vote, with two members voting present, a companion bill numbered SB 1326 moved through the Senate the same year, and neither the 2024 nor 2025 standard time proposals had gone nearly that far. A St. Louis University and YouGov poll found only 16 percent of Missouri voters actually wanted to keep switching the clocks twice a year, meaning the public was largely united on ending the practice even while their own representatives kept disagreeing on which fixed time to land on.

The Kansas City Problem

Representative Gragg's pitch for the 2026 bill leaned heavily on a very specific, very local worry rather than abstract sleep science. Kansas City straddles the Missouri and Kansas state line, and Gragg warned that if a neighboring state like Kansas or Illinois eventually chose permanent Standard Time while Missouri went the other direction toward permanent Daylight Saving Time, commuters crossing the state line every day would face a scrambled, mismatched metro area, part of it effectively an hour apart from the other for good, not just for a few months a year.

That scenario helps explain why Missouri's bill, unlike some other states' permanent Daylight Saving laws, was written to activate only once Congress itself makes daylight time the new national standard, rather than letting Missouri move first and risk a permanent, uncoordinated split with the states it borders. Of Missouri's eight neighboring states, five have leaned toward the same daylight time direction, while Oklahoma has preferred standard time and Arkansas and Tennessee have no active legislation either way, leaving Missouri boxed in on multiple sides by neighbors who have not yet agreed among themselves.

A Cross of Sunlight, Once a Year, for Exactly Four Minutes

Inside Bellefontaine Cemetery in St. Louis stands a mausoleum finished in 2021 that functions as an extraordinarily precise, single purpose sundial. A cross shaped gap was cut through a 32,000 pound, two foot thick block of granite at the top of a staircase, angled at exactly 27.9 degrees, the precise angle of the sun at solar noon on December 20, the birthday of the anonymous family who commissioned the building.

Once a year, at 11:58 in the morning on that single date, sunlight passes through the cut and projects a glowing cross measuring 4 by 8 feet onto the granite floor at the bottom of the stairs, holding there for about four minutes before the moment passes and the alignment will not repeat for another twelve months. A time capsule is sealed beneath the spot where the light lands. The same cemetery already held an older sun aligned monument, a pink granite obelisk built in 1990 by St. Louis sculptor William Conrad Severson, which casts a perfectly formed cross shaped shadow only at solar noon on the equinoxes and summer solstice.

A Half Scale Stonehenge in Rolla

Missouri's fascination with solar alignment is not confined to St. Louis. In Rolla, a half scale replica of Stonehenge stands with five trilithons arranged the same way as the original in England, and it is not purely decorative. A south facing stone in the arrangement carries a pierced brass plate that projects a small spot of sunlight onto a carved analemma pattern below, tracking the sun's changing position across the sky through the year in the same spirit as the ancient monument it copies.

The Only State Eclipsed Twice in Seven Years

Missouri sat inside the path of totality for two separate total solar eclipses within a single decade, an extraordinarily rare coincidence, and was the only state along the 2024 eclipse path that had also been crossed by the 2017 eclipse. Missourians had not seen anything like the 2017 event since 1869.

The two eclipses treated the state very differently. In 2017, totality swept across the width of Missouri, passing directly over both Kansas City and St. Louis, though Kansas City sat so close to the southern edge of the shadow that totality there ranged from a full minute in some neighborhoods down to nothing at all just blocks away, depending on which side of an invisible line through the city someone happened to be standing. Cape Girardeau saw less than two minutes of totality that year.

By 2024, the shadow's path had shifted into the state's southeastern corner, missing Kansas City and St. Louis entirely, with St. Louis reduced to a 99 percent partial eclipse rather than full darkness. Cape Girardeau, however, came out ahead the second time around, sitting almost exactly on the new centerline and experiencing over four minutes of totality, more than double its 2017 total. A third, smaller event had already crossed the state three decades before either total eclipse, an annular solar eclipse on May 10, 1994 that split Missouri diagonally in two. Missouri will not see another total solar eclipse until the year 2178.
