Everyone gets excited about the first day of Spring. For a long time I thought that it finally meant that we would have more daylight than night, because the Equinox was the day of equal day and night. But being the obsessive Weather Channel App user that I am, I noticed that the day of equal day and night happens a good week before the Equinox. On the actual Equinox, hanging out with us folks on the 35th Latitude, sunrise is a 6:58 am and sunset is at 7:07 pm. What was up with that? The quick answer is that the Equinox refers to the geometric center of the sun, which I assume that we are not supposed to ever look at. In any event, here is an article that explains it much better than I can.
