The Coalition for Permanent Standard Time (CpST) is a dedicated group of diverse organizations and individuals who support the elimination of biannual clock change in the United States through the restoration of permanent standard time. It’s time to ditch daylight saving time (DST).

Health Precautions

Delayed sunrise/sunset from DST increases the risk of depression, obesity, heart disease, cancer, and fatal car crashes

Dark Bus Stops

DST forces you to begin the day in the dark while you go to work or school. Standard time provides more daylight to start your morning.

Drowsy Driving

When adjusting to DST, evidence shows that drivers may be drowsy on the road, which negatively impacts public safety.

Circadian Wellness

Permanent standard time aligns closely with the body’s internal clock (circadian rhythm), which improves one’s health.


CpST advocates for the introduction and adoption of legislation (state/federal level) implementing permanent standard time throughout the United States.
