“Daylight saving time results in more darkness in the morning and more light in the evening...”
The sun, and the earth’s rotation does not care about daylight savings time and changing times on a clock does not increase or decrease the amount of light or darkness.
No the earth does does not care. But it does change the amount of light in the morning or evening. Morning and Evening are defined periods of our day. You get the extra hour in one or the other. You still get the same overall. I know you know this, but we all collectively agree that those terms mean parts of our day. We schedule our lives around the clock.
