With respect to the astronomical definition of the seasons, they line up reasonably well where I currently live (coastal) but not with where I grew up (interior). Likewise, holidays probably lined with the seasons at one point in their history. What we are likely seeing is the gradual shift between natural phenomena and a human construct, i.e. the calendar. We carry a lot of historical baggage with us, even if we rarely think of it.
