6 November 2017 - daylight saving time

When the aliens invade, they will not enslave humanity. It would be dangerous. They will look at our calendars, which have systems of bizarre tweaks to align the counting of days, months, and years, as if pretending that they fell into neat ratios. They will look at our irregularly-shaped time zones, and wonder why we have more than one. When they notice that large parts of the planet change time by an hour twice a year, on different schedules, they’ll throw up their tentacles. “With this joy in disorder, they could keep secrets from us,” the invaders will conclude. “We’d better exterminate them.”
