Here's something to think about- as the seasons change, most importantly during fall and spring, and the days get shorter and then longer again, do the days get shorter and longer linearly, or because of the ellipse in earth's orbit, do they get suddenly shorter in the fall for a time and then suddenly longer again in the spring? Doesn't it seem that way? Wait until it gets spring again and one day you walk outside and can't believe its still light so late...you'll see...
