There are so many oddities about English, so many irregularities, but I found something straightforward yesterday. Spring, summer, autumn and winter all have six letters, so it's possible to have them in quarterly lists withou the formatting needing any special attention. You can't do that with days or weeks. The other question on my mind: which capital city is closest to the equator? Is it Bangkok? Just asking, no real reason. I'll check and let you know sometime.
