What does a ‘spring ahead’ time change mean for Miami? When will it get light and dark?

We’ll lose an hour of sleep when we have to “spring ahead” in March.

But how else will we be affected? You’ll have extra light in the evening.

Let’s take a look at sunrise and sunset times in Miami when daylight saving time takes effect March 9, 2025, and then through the months until the next time change, when we “fall back” and return to standard time in November. That’s when we can reclaim our hour of sleep in November.

Here’s what to know:

When is daylight saving time?

Time change: Daylight saving time starts at 2 a.m. Sunday, March 9.

Sleep: Springing ahead means you’ll lose an hour of sleep when the time changes. You can make it up in November when we fall back in changing the time again.

Pro tip: Move your manually controlled clocks ahead an hour before going to sleep on Saturday night, March 8.

Why have we tinkered with the clock?

Saving energy: Daylight saving time is all about a desire to save energy by extending sunlight later in the day during spring and summer. A study conducted by the U.S. Department of Energy found that the four-week extension of daylight saving time in 2008 saved about 0.5% of the nation’s electricity per day, or 1.3 trillion watt-hours — which is enough to power 100,000 households for an entire year.

Safety: Studies have also shown that the extra hour of daylight has resulted in safer roads, lower crime rates and economic benefits.

Disruptions: Other concerns about daylight saving time have included disruptions to harvesting schedules for farmers, interference with religious observances based on solar and lunar time, and potential delays in reworking computer systems programmed to switch twice a year.
