[oeckqewt] September golden week

Consider dictatorially choosing dates during which most of the world could take a long vacation.  The most common such long vacation period in the United States, the week between Christmas and New Year's, is terrible because it falls in the middle of winter in the northern hemisphere, and inclement winter weather often impedes travel (something people often do for long vacations).

However, we can't just shift such a vacation period by 6 months, because that would place it in the middle of winter in the southern hemisphere.  This leaves Spring and Fall as possibilities.  We break the tie between them in favor of the northern hemisphere (because that's where most of the population and land mass is), choosing late September, around the autumnal equinox in the northern hemisphere.  In the northern hemisphere, seasonal lag will cause September to be more likely warmer (so less likely to have snow impeding travel) than March.

Of course, with a September golden week instead of the week between Christmas and New Year's, one won't be able to take a long vacation to somewhere warm in the dead of winter as Northern hemisphere residents like to do.  Though if you are rich enough to be doing that, maybe you are rich enough to pick your own vacations.
