Permanent Standard Time

In March 2022, the U.S. Senate approved the Sunshine Protection Act of 2021 (S 623), to make daylight saving time the new standard time across the nation. The Sleep Research Society (SRS) responded with a statement on the importance of Permanent Standard Time and the benefits it would have on the nation’s health. The U.S. House did not approve the legislation before its December expiration, though it was reintroduced in March 2023. This page will continue to be updated with resources and information surrounding Permanent Standard Time and the advocacy efforts of the SRS.

Become a Standard Time champion

You’re a sleep expert. That gives you the authority and credibility to educate members of your community, local media, and state and national legislators about sleep health. This time of year, right before and after most of the nation returns to standard time, offers the perfect time to speak out.

A summary of an SRS/AASM online workshop on the benefits of permanent standard time held on September 11, 2024 can help you get started. As participants learned, advocacy can be both meaningful and fun. At the workshop, California State Senator Roger Niello discussed his bill calling on California to adopt permanent standard time. In breakout groups, participants crafted personal stories to share with the media or others in their community. They also learned how to work effectively with legislators and become standard time champions. Participants left the workshop energized and with a clear message to use in their letters to the editor, op-eds, media appearances, emails to legislators, and legislative testimony.

You can use the same tactics to advocate for permanent standard time in the spring before the nation switches to daylight saving time, and year-round to support other sleep and circadian issues, including healthy school start times for teens and initiatives to prevent drowsy driving.

Science of Clock Change Video Series

The SRS teamed up with the AASM to create a series of 12 videos that explore how clock change impacts our lives. The video series was supported by funding from the AASM Foundation.
