Hi. I wrote the article. To tell you the truth, I&#x27;ve not (yet) found a reason why people in some places (it seems to be mainly North America and some in the UK) define seasons as beginning on solstices and equinoxes. Everyone just seems to repeat that that&#x27;s when the seasons start, even if they acknowledge that there are other definitions.<p>I&#x27;d be curious if anyone finds a good explanation of why and how this definition took root!
