As spring nears, people prepare for the yearly clock change. Daylight Saving Time (DST) shifts time forward for longer evening daylight. This adjustment impacts millions across the United States and Europe, affecting daily routines and sleep schedules.

When Will Daylight Saving Time Begin?
In the United States, DST starts on Sunday, 9 March 2025, at 2 a.m. Clocks will move forward by one hour, reducing sleep that night. The time shift extends daylight in the evening, making days feel longer. DST in the US will end on Sunday, 2 November 2025, when clocks return to standard time.

European countries will begin DST on Sunday, 30 March 2025, at 1 a.m. UTC. Clocks will move forward by one hour, adjusting local schedules. The time change will end on Sunday, 26 October 2025, when clocks are set back.

Why Was Daylight Saving Time Introduced?
DST was first suggested by Benjamin Franklin in 1784. However, Germany and Austria-Hungary officially introduced it in 1916. The goal was to save fuel by reducing artificial lighting in the evening.

The United States adopted DST in 1918 but lacked uniform rules. The Uniform Time Act of 1966 created a standard system for observance. Europe later introduced a coordinated DST system, ensuring all countries followed the same schedule.

Does DST Really Help Save Energy?
DST aims to reduce electricity use by increasing daylight hours. However, studies suggest energy savings may be minimal. More evening light reduces artificial lighting, but heating and cooling needs can offset the benefits.

The Sleep Foundation reports that people lose about 40 minutes of sleep after DST begins. This change can impact health, making it harder to adjust to new schedules.

Those affected by DST can adjust sleep schedules before the shift. Most modern devices update time automatically, but manual clocks need resetting. Planning ahead can help reduce the effects of losing an hour of sleep.
