California Daylight Saving Time 2021

CALIFORNIA — Longer evenings are just around the corner as residents of California and others prepare to spring forward, officially marking the start of daylight saving time — colloquially known as "daylight savings."

Daylight saving time in California begins at 2 a.m. this Sunday, March 14. You don’t have to do much to prepare — just remember to set your clocks ahead by one hour before going to bed Saturday night.

Daylight saving time starts each year on the second Sunday in March. The practice involves moving clocks forward one hour from standard time during the summer months and changing them back again in the fall. This year, daylight saving time ends on Nov. 7.

The basic point of daylight saving time is for us to make better use of natural daylight; however, not every state observes it. Hawaii doesn't, nor do the U.S. territories of Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands.

The time switch also passes without notice in Arizona, except in the Navajo Nation, which takes part in the biannual clock change to and from daylight saving time.

Arizona cited its hot climate in getting an exception; and Hawaii cited its tropical latitude, which means there isn't much variation in daylight in the summer and winter months.

But what about the vote in California to stay on daylight saving time? Back in 2018, Californians passed Proposition 7 by a 60 to 40 percent margin, saying that we prefer to remain on daylight saving time.

However, it is up to the California legislature and the US Congress to pass legislation to allow California to permanently opt out of daylight saving time, and that has not happened.

Daylight saving time has been around since World War I. But it became the law of the land more than 50 years ago with the Uniform Time Act of 1966, though the exact dates — now the second Sunday in March and the first Sunday in November — have changed some over the years.

Who really benefits from the time change?

Proponents may argue that longer evenings motivate people to get out of the house. The extra hour of daylight can be used for outdoor recreation such as golf, soccer, baseball, running and more. It also benefits the tourism industry.

However, critics say the drawbacks outweigh the benefits. The time change can mess with our body clocks and circadian rhythms, making for some restless nights and sleepy days. It also is difficult to quantify the economic cost of the collective tiredness caused by daylight saving time, but studies have found a decrease in productivity after the spring transition.

Tips To Help Adjust

So, what are the best ways to avoid sleep deprivation? The U.S. Centers for Disease Control and Prevention says this already affects about one-third of adults in the United States. Here are some tips:

• You know it's coming. Go to bed an hour early Saturday, and make sure you get seven to eight hours of sleep.
• Get the kids to bed early, too. They pay more attention to their internal clocks than timepieces, so implement the routine Saturday night to help them adjust to the brighter-than-usual bedtime, so they'll be set up for a good night's sleep before school Monday.
• Be patient with the kids. They may throw temper tantrums or show signs of frustration, but it's usually short-lived. Adults can also be cranky during the first several days after the time switch. You'll get over it, too.
• New baby? Pretend nothing has changed. That means taking the baby outside, even if it's cold, to help the baby's internal clock adjust. Getting 30 minutes of sunlight first thing in the morning will help you, too.
• Limit your vices. That shot of booze may seem like a good idea, but it will fragment your sleep. And, of course, limit your caffeine intake in the late afternoon and evening. Chamomile tea or a glass of warm milk is a better choice.
• Don't eat a big meal right before bedtime, either.
• If you are using the extra hour of daylight at the end of the day for exercise, make sure your session ends at least three hours before bedtime, because the energy boost that exercise gives you can cause insomnia.
• Wind down with a relaxing activity, such as a warm bath or shower, gentle stretching, or yoga.
• Let the sun shine in. Experts say that pulling back the curtains and allowing the sun to shine in the windows in the morning improves alertness during the day. You're also more likely to feel sleepy when it is time to go to bed.
• Turn off the bright lights an hour or two before you go to bed — yes, even the television, your computer and other electronic devices. Read a relaxing book or listen to soothing music instead.
• Don't give in to the urge for a long nap. Take a brief power nap if you need, but longer naps will disrupt your sleep schedule and make it more difficult to adjust to daylight saving time.
• Make your bedroom a sleep sanctuary — dark, quiet, well ventilated and at a slightly cooler temperature.
