Remember back in June when it was still light at bedtime? Now we’re lucky if we can get in a game of kickball or a walk with the dog after dinner.
That’s because we’re heading toward the winter, when the days are shorter and nights longer. The reason that happens is because the earth’s axis isn’t straight up and down, but at an angle. If you’ve ever seen a globe, think about how it’s tilted to the side.
People who live in the Northern Hemisphere — which includes Iowa and most of the earth’s population — have shorter days in winter because as the earth rotates around the sun we are tilted away from its light. That’s also why it’s colder. Brr!
People in the Southern Hemisphere, which includes countries like Australia, South Africa and Indonesia, have shorter and colder days in what we consider summer months.
The autumnal equinox, which happens Sept. 22 this year, is the day the length of day and night are nearly equal. It’s also the first day of fall.
But don’t be sad about less daylight. It will come back in the spring. Until then, you can do more cool evening activities, like playing ghosts in the graveyard, having an outdoor campfire or stargazing.
