California will shift to Daylight Saving Time on Sunday, March 8, 2026, in line with the national schedule followed across most parts of the United States. The time change will take place at 2:00 a.m., when clocks will move forward by one hour, officially marking the start of longer evening daylight.
The adjustment affects millions of residents, businesses, and institutions across the state. As California transitions from Pacific Standard Time to Pacific Daylight Time, the shift will temporarily disrupt sleep schedules but extend daylight availability in the evening, which remains the primary objective of this system.

Exact Date and Timing of the 2026 Clock Change
Daylight Saving Time in California will begin on March 8, 2026, at precisely 2:00 a.m. At that moment, clocks will jump forward to 3:00 a.m., effectively skipping one hour. This means the day will be shorter by one hour, and individuals will lose an hour of sleep on the night before the change.
The transition is uniform across the United States, except in regions that do not observe Daylight Saving Time. Most electronic devices, such as smartphones and computers update automatically, but manual clocks need to be adjusted to reflect the new time.
Full Daylight Saving Schedule for 2026
The time change in March marks the beginning of Daylight Saving Time, but it is not a permanent shift. The system continues until early November, when clocks are set back to standard time. The complete 2026 schedule for California is shown below.
| Event | Date | Time Adjustment | Outcome |
|---|---|---|---|
| DST Begins | March 8, 2026 | 2:00 a.m. to 3:00 a.m. | One hour lost |
| DST Ends | November 1, 2026 | 2:00 a.m. to 1:00 a.m. | One hour gained |
This pattern has been followed in the United States since 2007, when federal law extended the duration of Daylight Saving Time to its current period of about eight months each year.
Shift from PST to PDT Explained
California operates on Pacific Time, but the time offset changes during Daylight Saving Time. During standard time, the state follows Pacific Standard Time, which is eight hours behind Coordinated Universal Time.
California switches to Pacific Daylight Time, which is seven hours behind Coordinated Universal Time, when Daylight Saving Time starts. This one-hour difference plays an important role in scheduling across different regions, especially for businesses that operate internationally.
The change also affects daylight patterns. After the transition, sunrise and sunset times occur approximately one hour later. Darker mornings give way to longer evening daylight, a phenomenon that many perceive as advantageous for outdoor activities and extended work hours.
Why Daylight Saving Time Is Implemented
Daylight Saving Time is designed to make better use of natural daylight during the warmer months of the year. By shifting the clock forward, more daylight is available in the evening hours, reducing the need for artificial lighting and supporting economic and social activities.
The concept was formally standardized in the United States by the Uniform Time Act, and later amendments extended its duration. Currently, Daylight Saving Time lasts approximately 34 weeks each year, covering nearly two-thirds of the calendar year.
Immediate Effects on Daily Routine
The most noticeable impact of the time change is the loss of one hour of sleep on the first day. This can temporarily affect sleep patterns, concentration levels, and overall productivity. Many individuals take a few days to fully adjust to the new schedule.
Morning routines may feel more difficult because sunrise occurs later, especially for those who start their day early. However, the extended daylight in the evening often leads to increased outdoor activity, longer business hours, and more flexibility in daily planning.
Changes After the Clock Moves Forward
After the transition to Daylight Saving Time, several changes can be observed in daily life. These include
- Later sunsets that extend daylight into the evening
- Delayed sunrise times leading to darker mornings
- Shorter day due to the one-hour shift
- Temporary adjustment in sleep cycles
These changes remain in effect until the end of Daylight Saving Time in November.
Devices That May Need Manual Adjustment
While many digital systems update automatically, several devices still require manual changes. Ensuring that all clocks are updated is important to avoid confusion in daily schedules.
- Wall clocks and traditional watches
- Vehicle clocks and dashboards
- Kitchen appliances such as ovens and microwaves
- Office equipment not connected to the internet
Updating these devices before starting the day can help maintain accurate timekeeping across all activities.
Areas That Do Not Follow Daylight Saving Time
Not all regions in the United States observe Daylight Saving Time. Hawaii and most of Arizona remain on standard time year-round. In addition, U.S. territories such as Puerto Rico, Guam, and the U.S. Virgin Islands also do not follow the clock change system.
California continues to follow the federal schedule, and any change to make Daylight Saving Time permanent would require approval at the national level. Although discussions have taken place in recent years, no final decision has been implemented.
Comparison Between Standard Time and Daylight Saving Time
The difference between standard time and daylight saving time primarily lies in the distribution of daylight throughout the day. The table below highlights the key differences.
| Feature | Standard Time | Daylight Saving Time |
|---|---|---|
| Time Zone | PST | PDT |
| UTC Offset | UTC minus 8 | UTC minus 7 |
| Daylight Pattern | Earlier sunrise and sunset | Later sunrise and sunset |
| Duration | November to March | March to November |
This comparison shows that the total amount of daylight does not change, but its distribution shifts to later hours in the day during Daylight Saving Time.
Although the initial adjustment can affect sleep and daily routines, the system is still followed across most of the United States. Understanding the exact timing and impact of this change helps residents and businesses plan effectively and avoid disruptions during the transition period.
