The Pope Who Deleted Ten Days and Made Everyone Lose Their Minds Over Rent and Their Souls

On February 24, 1582, Pope Gregory XIII issued the papal bull *Inter gravissimas*, thereby creating the Gregorian calendar and setting up one of history's most delightful administrative disasters. The Julian calendar, introduced by Julius Caesar in 45 BCE, had been running about 11 minutes slow per year—which doesn't sound like much until you realize that by the 16th century, the calendar had drifted a full ten days out of sync with the solar year. Easter was threatening to eventually occur in summer, which would have made for very confused ecclesiastical celebrations. Gregory's solution was beautifully simple and catastrophically complicated: delete ten days from existence. When Catholic countries implemented the calendar later that year, Thursday, October 4, 1582, was immediately followed by Friday, October 15, 1582. October 5-14 simply never happened. The chaos was magnificent. Landlords demanded full month's rent despite the month being ten days shorter. Workers rioted, convinced they'd been robbed of ten days of their lives. Some people genuinely believed they'd aged ten days instantly or that they'd lost ten days of their eternal souls. Protestant countries, naturally, refused to adopt a *Catholic* calendar out of sheer principle, creating a situation where neighboring towns existed in different dates. Britain and its colonies didn't switch until 1752—by which point they had to delete eleven days. Sweden attempted a gradual transition that failed so spectacularly they had to add back the days they'd removed. The Orthodox Church in some countries still hasn't switched, which is why they celebrate Christmas on January 7th. All because the Pope really wanted Easter at the right time.
