Wisconsin lawmakers have introduced a bill that would eliminate the use of Daylight Saving
Time (DST) in the state, establishing a permanent standard time throughout the year. The
proposal, sponsored by Representative Gustafson and Senator Cabral-Guevara, is aimed at
ending the twice-yearly time change, which research suggests may have negative effects on
public health and safety.
According to the bill’s sponsors, studies show that the transition to and from DST can lead to an
increase in workplace injuries, traffic accidents, and disruptions to mental health and
productivity. Parents of young children have also reported difficulties adjusting to the time
change, making the transition period particularly challenging for families.
Under current law, DST begins on the second Sunday in March and ends on the first Sunday in
November. Federal law generally requires states to observe DST unless they opt out entirely in
favor of permanent standard time. Since Wisconsin is located entirely within one time zone, it
has the option to make this change statewide. Arizona and Hawaii are among the states that
have already chosen to remain on standard time year-round.
The debate over Daylight Saving Time (DST) versus Standard Time continues as experts weigh
in on the potential effects of making DST permanent. The American Academy of Sleep Medicine
(AASM) argues in favor of permanent Standard Time, citing its alignment with the body’s natural
circadian rhythm and its benefits for sleep quality, cognition, and cardiovascular health.
According to AASM, seasonal time changes disrupt sleep patterns and have been linked to
increased risks of stroke, heart disease, and workplace injuries. The organization also warns
that making DST permanent would result in darker mornings in many parts of the country,
potentially increasing traffic accidents and safety risks, especially for children commuting to
school.
Despite expert recommendations favoring Standard Time, legislative efforts have focused on
making DST permanent. The U.S. Senate unanimously passed the Sunshine Protection Act,
which proposes ending the biannual time changes and keeping the country on DST year-round.
Supporters of the bill argue that later sunsets would provide economic benefits, improve outdoor
activity opportunities, and enhance public safety by reducing crime rates. However, the bill has
stalled in the House, with lawmakers citing other legislative priorities. As the debate continues,
the United States remains divided on whether to adopt a permanent time standard and, if so,
whether Standard Time or DST would be the better choice.
The bill is open for co-sponsorship until March 19, 2025. If passed, Wisconsin would join a
growing number of states considering similar legislation to eliminate seasonal clock changes.
