September 15

September 15 is the 259th day of the year, and the American record for it runs from 1776 to 2020 — a span of 244 years. The entry that anchors it: U.S. President Lyndon B. Johnson, 1966.

The revolutionary generation left its own mark on the date. In 1776, American Revolutionary War — British forces successfully land at Kip's Bay, forcing the Continental Army, which was already withdrawing from New York City, to cede control of the lower half of Manhattan Island.

The antebellum decades brought the date closer to the country’s central argument. In 1862, American Civil War — Confederate forces captured the Union garrison at Harpers Ferry, Virginia, taking more than 12,000 prisoners.

After 1945 the date reflects a country operating at global scale. In 1963, Baptist Church bombing — four children are killed in the bombing of an African-American church in Birmingham, Alabama, United States. Three years on, in 1966, U.S. President Lyndon B. Johnson, responding to a sniper attack at the University of Texas at Austin, writes a letter to Congress urging the enactment of gun control legislation. Then, in 1981, the John Bull becomes the oldest operable steam locomotive in the world when the Smithsonian Institution operates it under its own power outside Washington, D.C. The same year, the Senate Judiciary Committee unanimously approves Sandra Day O'Connor to become the first female justice of the Supreme Court of the United States.

The most recent entries fall within living memory. In 2008, Financial crisis of 2007–2008 — the global financial services firm Lehman Brothers filed for bankruptcy while holding over $600 billion in assets, the largest such filing in U.S. history. Then, in 2020, Signing of the Abraham Accords occurs in Washington, D.C., normalizing relations between Israel and two Arab nations, the United Arab Emirates and Bahrain.

The date is also a birthday. Among the Americans born on September 15: James Fenimore Cooper (1789), American novelist, short story writer, and historian; James Gates Percival (1795), American poet, surgeon and geologist; George Franklin Grant (1846), African-American educator, dentist, and inventor; Edward Bouchet (1852), American physicist and educator; and Jan Ernst Matzeliger (1852), Surinamese-American inventor.

September 15 is also a date of endings. Among the Americans who died on it: Abraham Clark (1794), American police officer and politician; William Wales (1907), English-American inventor (born c. 1838); Milton Sills (1930), American actor and screenwriter; and Thomas Wolfe (1938), American novelist.

The date carries formal observance as well — International Day of Democracy; The beginning of German American Heritage Month, celebrated until October 15; and The beginning of National Hispanic Heritage Month, celebrated until October 15 (United States). What holds these 8 entries together is nothing more than the calendar, and nothing less. 244 years separate the earliest from the latest, and each was once simply the present day.
