Daylight Saving Time begins Sunday — here’s how to prepare

More daylight is just days away. This weekend, the clocks will advance by an hour, and you will notice the days getting longer in the evening. Yes, we will have more time in the sun, but the change comes with disruptions in sleep patterns and a shift in our circadian rhythm, which is essentially our body’s internal clock. Not all experts support the continuation of this change.

When does daylight saving time start?

Daylight saving time begins Sunday at 2 a.m. local time. The start of daylight saving time usually means you’ll move forward. You’ll lose an hour of sleep, but you’ll get longer periods of daylight in the evening.
