Mississippi: Does the state observe daylight saving time?
Observes DST, law to go year-round
Mississippi observes daylight saving time but passed a 2021 law to stay on it year-round if Congress allows.
The Governor signed House Bill 1062, the "Sunshine Protection Act," on March 17, 2021. It applies only if Congress changes federal law to let states keep daylight saving time all year, and it does not depend on neighboring states. Later bills on the same subject in 2025 and 2026 did not pass.
Conditions
- Takes effect only if Congress amends 15 U.S.C. 260a to allow year-round daylight saving time
What the law says
If the United States Congress amends 15 USC 260a to authorize states to observe daylight saving time year-round, daylight saving time shall be the year-round standard time of the State of Mississippi and all of its political subdivisions.
