OK HB3137

Establishes Oklahoma's standard time as Central Standard Time (solar time of the 90th meridian west of Greenwich) for the state and all political subdivisions

Oklahoma would become exempt from daylight saving time effective January 1 of the year following when any two of four neighboring jurisdictions also exempt themselves: Arkansas, central time zone portions of Kansas, Missouri, or central time zone portions of Texas

If federal law is passed authorizing year-round daylight saving time, Oklahoma would automatically adopt permanent daylight saving time statewide

Legislative findings cite health, safety, education, and economic harms from seasonal clock changes, noting that permanent daylight saving time trials during WWII and the 1970s Oil Crisis were repealed due to negative effects

Effective date is November 1, 2026
