I recently had a discussion with a friend about Daylight Saving Time and it reminded that there is actually a lot of misunderstanding about it. Most of the complaints I hear about DST come in the fall when it ends. I hear people complain that, with the time change, it will be getting dark sooner, and because of that they hate Daylight Saving Time. They shouldn’t “be hating” on DST for the early darkness, because the early darkness is a result of our return to Standard (that means unaltered and un-adjusted) Time.
Why do we use DST?
The rational behind DST is explained simply in the Wikipedia article Daylight Saving Time, “[DST] is the practice of advancing clocks during the lighter months so that evenings have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.” *There is a whole lot more to the original motivation and the motivation to expand the date range for DST, but I wanted to keep it simple here. If you really want to learn about DST, check out the link above and do some reading on your own.
When someone complains about DST and says they are not happy that the sun will set at 5:18 pm on November 3, they are actually saying that they wish the sun had set 5:19 on November 2 and 5:20 on November 1, instead of 6:19 and 6:20. (You can find sunrise and sunset times here.) What they really mean is that they wish we used DST time all year long, so that the sun would set at 6:18 pm on November 3 just a minute earlier than it did the day before. DST always means that the sun sets later than it would on ST.
What if we didn’t use DST at all?
What would the spring and summer months be like? The chart I shared earlier shows that for Ohio, the sun would be rising at 4:51 am (That’s EARLY!) in the middle of June and setting at 8:03 pm (its latest) at the end June. Daylight Saving Time was instituted to help people use that hour of sunlight between 5 am and 6 am by moving it to the end of the day between 8 pm and 9 pm, which makes a lot of sense to me.
What if we used DST all year long?
We could, but it would mean really late sunrises in the winter. The chart shows sunrises as late as 8:52 am in December and January. That seems awful late to me.
What do you think?
When we do time changes in the spring and fall, they feel really drastic and maybe unnecessary, but when we look at what those time changes do for us in June/July and December/January is makes more sense. What do you think? Feel free to comment below and answer the survey below.
