SB 22-135

Senate Bill 22-135, also known as "Standard Time in Colorado," proposes that Colorado stops observing daylight saving time and remains on Mountain Standard Time (MST) all year round. If voters approve this bill in the November 2022 election, Colorado will no longer switch its clocks forward one hour starting from 2023. This change would affect everyone in the state, impacting daily routines like work schedules and school times. The bill has been signed into law, meaning that if approved by voters as expected, Colorado will move to year-round MST beginning next year.

Official Summary

Currently, "United States Mountain Standard Time" (MST) is the standard time within Colorado, except during the period of daylight saving time (i.e., the second Sunday in March to the first Sunday in November) when time is advanced one hour. If the registered electors of the state approve the bill at the November 2022 general election, the entire state will be exempt from observing daylight saving time in the future, beginning in 2023, and MST will be the year-round standard time in the state.(Note: This summary applies to this bill as introduced.)
