Spring Forward 2026: What to Know About Daylight Saving Time

Each year, Americans adjust their clocks as daylight saving time begins. It may seem like a small change, but shifting the clock by one hour can affect our routines, sleep, and overall well-being. Here is a quick guide to what it means in 2026.

When Does Daylight Saving Time Start in 2026?

Daylight saving time begins on Sunday, March 8, 2026, at 2:00 a.m. local time. Clocks move forward one hour to 3:00 a.m.

The schedule follows the Uniform Time Act, which standardized time changes across the country. Most states observe daylight saving time from the second Sunday in March through the first Sunday in November. However, most of Arizona and all of Hawaii do not participate.

How Does It Work?

In the spring, we “spring forward” by setting clocks ahead one hour. In the fall, we “fall back” and return to standard time.

The shift gives us more daylight in the evening and less in the early morning, which many people appreciate as warmer months approach.

Why Do We Have It?

Daylight saving time was first introduced during World War I to conserve energy. It returned during World War II and later became standardized nationwide.

The goal was to reduce energy use and encourage evening activity. While the energy savings today are debated, extended daylight hours continue to benefit businesses and outdoor recreation.

Effects on Our Health

The one-hour loss of sleep can temporarily disrupt circadian rhythms. Some studies note a short-term increase in fatigue, reduced focus, and even a slight rise in heart-related incidents and accidents right after the change.

On the positive side, longer evenings bring more natural light, which can support mood and overall well-being. Most people adjust within a few days.
