Easter arrived too late in spring. All because the Earth year is about eleven minutes short of 365¼ days. Without a calendar correction, Easter would eventually have fallen in summer, and Christmas in the spring. So Pope Gregory XIII appointed a commission. It proposed eliminating three leap years every four centuries (years ending in 00, unless divisible by 400). That would prevent further creep of the calendar against the seasons. But to reset the calendar immediately, ten days had to be eliminated. The pope decreed the new calendar should start in October 1582. The day after October 4 would not be October 5, but October 15. This was just months away. Only Italy, Spain, and Portugal made deadline. Many people feared their lives were being shortened by ten days. The pious worried that saints might not listen to prayers that were ten days late. Everyone’s birthday moved up ten days too, so 365 days would pass between one birthday and the next. Rents, interest, and wages had to be discounted for that October, since it now had only twenty-one days. A mob in Frankfurt rioted against the pope and his mathematicians. France made the change in December. Parts of the Low Countries jumped from December 21, 1582, directly to January 1, 1583, skipping Christmas. Most Catholic countries adopted the Gregorian calendar by 1584. But Europe became a patchwork of calendars. You could cross a border and go backward or forward ten days. (Makes the international date line kid stuff.) The Julian calendar (see here) held on until 1752 in Britain and its colonies, and right through 1918 in Russia. As a result, the old Soviet Union used to celebrate its October Revolution in November.—RA Also January 1: 1801: Piazzi Discovers Ceres, First Known Asteroid 1845: Telegraph Helps Capture Murderer John Tawel 1915: Aspirin Tablets Replace Powdered Form (see here) Also Sixteenth Century: May 4, 1536: C U @ the Piazza (see here) January 2 1870: Building the Brooklyn Bridge Construction begins on the Brooklyn Bridge. It’s the first suspension bridge to use steel—rather than iron—cables. Conceived in 1867 by famed bridge designer John Augustus Roebling, it was by far the world’s longest suspension bridge, with a deck that connected Manhattan and Brooklyn suspended by cables hung from two neo-Gothic towers that pierced the skyline. Not precisely certain of the strength of his materials, Roebling designed the bridge to be six times stronger than it had to be. As a fail- safe, he added straight, diagonal cables to stiffen the superstructure. They make the bridge not a true suspension bridge (which has just vertical stringers, or suspender cables, hanging from huge, curved catenary cables) but a hybrid of suspension and cable-stayed design. That hybrid also gives the steel webwork its characteristic—and mesmerizing—crisscross appearance. Roebling died of tetanus in 1869, the result of an injury sustained while surveying the bridge site. John’s son Washington assumed the title of chief engineer, but tragedy struck again when he became ill with the bends (severe decompression sickness) after rapidly exiting one of the bridge’s caissons. It fell to Washington’s wife, Emily Warren Roebling, to supervise construction of the bridge. Though never formally trained as an engineer, Emily had studied alongside her husband and began her own research after he became bedridden. Historian David McCullough credits Emily with saving the project, and she rode alongside President Chester Arthur during the ceremonial opening of the bridge, in May 1883. The Brooklyn Bridge has over the years carried P.T. Barnum’s elephants, light-rail, and six lanes of automotive traffic, as well as the thousands of pedestrians who left Lower Manhattan after the attacks of September 11, 2001. But it’s not for sale, no matter what that guy on the corner tells you.—KB
