Why does the day length change during the year?

Earth's rotational axis is tilted about 23.5° relative to its orbit, so as the planet circles the sun each hemisphere faces toward the sun for part of the year and away for the other. That tilt is why days grow longer around each summer solstice and shorter around each winter solstice — the effect is strongest near the poles and vanishes at the equator.
