"The lowest prices of the season"

I’ve always been intrigued when stores send out flyers with that phrase. Is their definition of season the same as ours (Winter, Spring, Summer, Fall)? Are the start and stop dates the same as the “official” ones for the seasons? How come they just don’t say, “the lowest prices of the Winter”?

I just got a Kohl’s flyer (I live in Illinois) with “Lowest prices of the season” on the front, but there’s no defintion of what that means. The items on sale aren’t clearance merchandise or particularly seasonal, they run the gamut of what’s in the store - athletic shoes, kitchen electrics, towels, etc. So in retail, what’s the definition of “season”?

“Season” is an extremely vague term. There is no official definition. The US NWS uses, e.g., March to May as “Spring”. Many resorts use Memorial Day to Labor Day as “Summer.” Many countries vary quite a bit as to what is regarded as the end points of seasons. Many places don’t even have 4 seasons.

As far as stores go, their “seasons” in no way have to correspond to anybody else’s idea of seasons. E.g., when is “the Christmas season”?

Note that “lowest prices of the season” excludes later still lower “sales prices” during the same season.

How to tell if your TV weatherman is an idiot: He tells you that solstices and equinoxes are the “official” starting points of seasons.
