Bill > HB490

This bill proposes a change to Missouri state law regarding daylight saving time (DST), which is the practice of advancing clocks during summer months to extend evening daylight. Specifically, the bill mandates that on November 2, 2025, Missouri will set its clocks back to standard time and will not participate in daylight saving time afterward. However, the bill includes a provision that if the federal government ultimately adopts daylight saving time as the new standard time, Missouri would then adjust its clocks to conform with the new federal standard. This proposed legislation reflects growing national discussions about the potential drawbacks of biannual time changes and provides a mechanism for the state to opt out of DST while maintaining flexibility to follow federal guidance if national standards change. The bill represents a potential step towards ending the twice-yearly clock adjustments that have been criticized for disrupting sleep patterns and potentially causing minor health and productivity impacts.
