We may have lost touch with our agrarian roots but I don't think we have stopped noticing when flowers and leaves start appearing, birds start nesting, and many other signs of the beginning of Spring in the normal human sense. And we still talk about Spring being early or late, so we can't be thinking about the Vernal Equinox when we say it. I did not say that Astronomy was not a science, which it plainly is. But Astrology is certainly not a science (even if some think it is), and as you may see from other posts (including some of your own), the cycle of the seasons is commonly associated with astrological interpretations of astronomical events. That is not science, it is scientism - the pretense of a scientific basis for such interpretations.
