Kate's Corner: Daylight Saving Time

By  | 

BRIDGEPORT, W. Va. (WDTV) - Daylight saving time officially ends at 2:00 AM on Sunday November 6th. So as we think about gaining that extra hour of sleep this weekend, I thought I would tell you a brief history of springing forward and falling back. Before we talk about the history though, let's quickly explain why we even need to shift our clocks.

Due to the earth's tilt, length of days vary depending on the time of the year. Days are longer during the summer in the northern hemisphere because the earth is inclined toward the sun. This allows sunlight to fall at higher latitudes and the sun rises higher in the sky. So with longer days, we shift our clocks to move an hour of daylight from the morning to the evening.

Now to the history portion, Germany was the first country to enact Daylight Saving Time in 1916. The country implemented the practice to conserve energy during World War I and the United Kingdom quickly followed suit a few weeks later.

Here in the United States, the practice was put into law in 1918 by President Woodrow Wilson but back then it was called fast time. Fast time stopped once the war ended but FDR brought it back in 1942 during World War II and it has been observed ever since.

However, not all of the United States changes their clocks in the spring and fall. Hawaii and Arizona are the two states that do not shift back and forth. Around 70 counties around the world observe it Daylight Saving Time today.
