In most of the United states, there are about 4,600 hours of available sunlight each year.
For the eight months that clocks are ahead, the available light is shifted from the morning into the evening. Early risers tend to abhor that change, and night owls tend to welcome it. But does daylight saving actually save daylight?
In order to get all of the available sun throughout the year, you’d have to wake up by 5am every day through the warmer months. That might sound pretty brutal, but without daylight saving, it’d be even worse. In that case, you’d have to get up by 4am.
Either way, if you’re not an extreme early riser, you’re going to miss out on a lot of morning sun. If you wake up at 7:30am and go to bed at 11:30pm, for example, you would soak in 4,203 of the available 4,568 hours of daylight throughout the year, as long as daylight saving is in effect. That’s 92% of all of the available light.
That’s 238 more hours of sun than you’d get without daylight saving, which means that, believe or not, daylight saving really can save you some daylight.
