Cities within 60° of the equator, as in the daily puzzle. The solstices are when the puzzle is most generous: day lengths are spread over hours, not minutes.
After the solstice
Day length changes slowest right around a solstice, by seconds a day, and then speeds up toward the next equinox. The earliest sunset and latest sunrise don’t fall exactly on the solstice either: they’re shifted by a couple of weeks because the length of the solar day varies slightly through the year.
