Daylight Saving Time Schedule in Missouri for 2026
Daylight Saving Time (DST) changes dictate how clocks are synchronized throughout Missouri. For the year 2026, the transitions follow federally mandated guidelines, shifting clocks forward in the spring and backward in the autumn.
- Spring Forward (Start of CDT): Sunday, March 8, 2026. Clocks move forward from 2:00 AM to 3:00 AM local time, resulting in a shorter day and the loss of one hour of sleep, bringing St. Louis to UTC-5.
- Fall Back (Return to CST): Sunday, November 1, 2026. Clocks move backward from 2:00 AM to 1:00 AM local time, granting an extra hour of sleep and returning St. Louis to UTC-6.
Mismanaging these transitions can lead to missed flights at St. Louis Lambert International Airport (STL), scheduling errors for rail freight, and missed deadlines for financial settlements. Setting all connected devices to automatic time zone updates prevents these disruptions.
