You miss the point entirely. Spring is *defined* as the season when flowers and leaves (re)appear, birds nest, etc. That is what Spring means. And, yes, it starts at different times in different places and in different years. For that reason the start of Spring can not be fixed by any astronomical event such as the vernal equinox, which will occur *at some time* in Spring, just as the Summer Solstice occurs at some time in Summer. That is how human beings relate to the world around them. Most know nothing about equinoxes or solstices, though no doubt they pick up references to them in their diaries, newspapers and other media and regard them in much the same way as their "star signs" and other astrological nonsense.
