Bill > HB5400

This bill amends the Time Standardization Act to exempt Illinois from observing daylight saving time, meaning the state would remain on standard time year-round, specifically United States standard central time. This change would take effect on January 1st of the year following or coinciding with the date when both Iowa and Missouri are also exempted from daylight saving time under federal law. The bill's findings section explains that seasonal clock changes are disruptive and that permanent standard time is recommended by sleep medicine experts, unlike permanent daylight saving time which has historically been repealed due to negative effects. The Uniform Time Act of 1966 is a federal law that establishes time zones and the observance of daylight saving time, and this bill seeks to utilize an exemption provision within that act.
