Well, it’s that time of the year again. We reach for our phones and check what time it is because we never remember if we have to go forward or backward in time or we do not know if we gain or lost an hour of sleep. In this blog post, we have decided to explain Daylight Saving Time aka DST. We agree that it tends to be quite confusing and some of us do not actually know why we observe DST in some states.
What is DST?
Daylight Saving Time (DST) is the practice of turning the clock ahead as warmer weather approaches and back as it becomes colder again so that people will have one more hour of daylight in the afternoon and evening during the warmer season of the year. The U.S. Energy Policy Act of 2005 changed to Daylight Saving Time, extending it three weeks earlier in the spring and one week later in the fall. Starting March 11, 2007 clocks spring ahead an hour on the second Sunday in March and fall back on the first Sunday in November.
Why do we shift our clocks?
The assumption behind the change was that it would decrease the need for artificial light sources and, as a result, save energy. Allowing us to use more of sunlight during the day and less use of the artificial lighting in our homes and workplaces allow us to save energy.
Who doesn’t do DST?
The state of Arizona and Hawaii do not observe the time change due to the fact that the sunlight is enough for them throughout the day that no change is required to really save energy.
