Geocentric Science

Spring ahead! Fall behind! Have you ever wondered why we lose an hour in the fall and then gain an hour in the spring?

The answer lies in energy use. We use less energy in lighting if we take advantage of the daylight hours, so by adjusting the clocks by an hour, we are able to do so.

Everyone doesn’t observe Daylight Savings Time. Some places that are closer to the equator (such as Hawaii and Puerto Rico) do not observe Daylight Savings Time. They receive a lot of sunlight throughout the year, and therefore, the daylight length doesn’t vary very much. As a result, it would not make sense for these places to change their clocks.
