The United Kingdom is not on Greenwich Mean Time (GMT) all year. During Daylight Saving Time (DST) the correct time zone is British Summer Time (BST).

Today, most Americans spring forward (turn clocks ahead and lose an hour) on the second Sunday in March (at 2:00 A.M.) and fall back (turn clocks back and gain an hour) on the first Sunday in November (at 2:00 A.M.).

In California, for example, voters back in 2018 overwhelmingly passed Proposition 7 in an effort to establish year-round daylight saving time. Since then, however, legislation seeking federal authorization to do so has stalled in the legislature. The legislation would put an end to the practice of daylight saving time.

The main purpose of Daylight Saving Time (called “Summer Time” in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening. Countries have different change dates. According to some sources, DST saves energy.

Immediately following the “spring ahead” time shift, people can find it difficult to fall asleep at night and wake up in the morning. This can lead to less hours of sleep overall, and that sleep deprivation can pose safety risks, including a higher likelihood of motor vehicle accidents on days following the time shift.

Consider these four benefits of daylight saving time:

• There’s more light to enjoy in the evening.
• The crime rate drops during daylight saving time.
• It minimizes energy consumption (and lowers your costs).
• It lowers the incidence of traffic accidents.
• Reset your clocks the night before.
• Catch some extra ZZZs.

Researchers have also noted negative effects that occur during the transition from DST to Standard Time in November. In addition to sleep loss, people are at greater risk of mood disturbance, suicide, and being involved in traffic accidents during both bi-annual transition periods.

Critics of DST are correct about one thing: The biannual clock switch is bad for health and welfare. It wreaks havoc on sleep cycles. In March, in the week after the country “springs forward,” heart attacks increase 24%. There’s also an uptick during the week in November when the clocks “fall back.”
