Yes, Oklahoma does observe Daylight Saving Time, and has since the Uniform Time Act of 1966 standardized the practice. Clocks spring forward one hour in March and fall back in November, on the same schedule as most of the country. A 2024 state law signals Oklahoma’s preference for permanent Daylight Saving Time, but that change cannot take effect unless Congress authorizes it, and Congress has not.
When Oklahoma’s Clocks Change
Most of Oklahoma sits in the Central Time Zone, with a small part of the western panhandle in Mountain Time. In the colder months, the state runs on Central Standard Time. When DST begins, it shifts to Central Daylight Time, one hour ahead.
The transition dates come from federal statute. Clocks move forward at 2:00 a.m. on the second Sunday of March and back at 2:00 a.m. on the first Sunday of November.1Office of the Law Revision Counsel. 15 USC 260a – Advancement of Time or Changeover Dates In 2026, clocks sprang forward on March 8 and will fall back on November 1.
Why Oklahoma Can’t Change the Rules on Its Own
Daylight Saving Time is governed by the Uniform Time Act of 1966, codified at 15 U.S.C. ยง 260a. The law sets DST’s start and end dates nationwide and gives the Department of Transportation authority over time zone boundaries.
States have exactly one opt-out available: they can stay on standard time year-round. Arizona and Hawaii have done so, along with five U.S. territories. What a state cannot do under current federal law is adopt permanent Daylight Saving Time. The statute only authorizes exemption from the “advancement of time,” so a state can refuse to spring forward but cannot lock its clocks in the sprung-forward position without Congress changing the rules.1Office of the Law Revision Counsel. 15 USC 260a – Advancement of Time or Changeover Dates
That matters here because Oklahoma’s preferred outcome is permanent DST, not permanent standard time. The state needs a green light from Washington before anything changes.
The 2024 Law and the Stalled Federal Bill
In April 2024, Governor Kevin Stitt signed Senate Bill 1200, authored by Senator Blake Stephens. The law declares that Oklahoma will adopt year-round Daylight Saving Time the moment federal legislation authorizes states to do so.2Oklahoma Senate. Bill to Lock Oklahoma’s Clock Approved by Governor Until that happens, the law has no practical effect. Clocks keep changing twice a year.
Oklahoma is one of at least 19 states with similar conditional laws on the books. Florida was the first in 2018, and Texas joined in 2025. None of these laws can take effect without federal action.
The federal vehicle most often cited for that change is the Sunshine Protection Act. The Senate unanimously passed a version in 2022, but it died in the House. A new version was introduced in the 119th Congress in January 2025 as H.R. 139 and referred to the House Committee on Energy and Commerce, where it has sat since.3Congress.gov.

The 2025 Effort to Go the Other Direction
Not everyone in the state agrees that permanent DST is the right call. In early 2025, Representative Kevin West introduced House Bill 1223, which would have repealed SB 1200 and locked Oklahoma on standard time year-round, something the state could legally do without waiting for Congress.4Oklahoma Legislature.

With HB 1223 defeated, SB 1200 remains on the books. Oklahoma’s official position is permanent Daylight Saving Time whenever Congress permits it. Until then, the clocks keep moving.
