February 9

February 9 is the 40th day of the year, and the American record for it runs from 1775 to 2001 — a span of 226 years. The entry that anchors it: American Civil War, 1861.

The earliest entries here predate the republic entirely. In 1775, American Revolutionary War — the British Parliament declares Massachusetts in rebellion.

The antebellum decades brought the date closer to the country’s central argument. In 1825, after no candidate received a majority of electoral votes in the previous year's presidential election, the United States House of Representatives chose John Quincy Adams as president in a contingent election. Then, in 1861, American Civil War — Jefferson Davis is elected the Provisional President of the Confederate States of America by the Provisional Confederate Congress at Montgomery, Alabama.

Reconstruction and the years that followed added their own entries. In 1870, US president Ulysses S. Grant signs a joint resolution of Congress establishing the U.S. Weather Bureau. Then, in 1889, US president Grover Cleveland signs a bill elevating the United States Department of Agriculture to a Cabinet-level agency.

After 1945 the date reflects a country operating at global scale. In 1965, Vietnam War — the United States Marine Corps sends a MIM-23 Hawk missile battalion to South Vietnam, the first American troops in-country without an official advisory or training mission. Six years on, in 1971, Apollo program — Apollo 14 returns to Earth after the third human Moon landing.

The most recent entries fall within living memory. In 2001, the Ehime Maru and USS Greeneville collision takes place, killing nine of the thirty-five people on board the Japanese fishery high-school training ship Ehime Maru, leaving the USS Greeneville (SSN-772) with US $2 million in repairs, at Pearl Harbor.

The date is also a birthday. Among the Americans born on February 9: Thomas Paine (1737), English-American philosopher, author, and activist; George W. Campbell (1769), Scottish-American lawyer and politician, 5th United States Secretary of the Treasury; William Henry Harrison (1773), American general and politician, 9th President of the United States; Hyrum Smith (1800), American religious leader; and Samuel J. Tilden (1814), American lawyer and politician, 28th Governor of New York.

February 9 is also a date of endings. Among the Americans who died on it: Seth Pomeroy (1777), American general and gunsmith; Paul Laurence Dunbar (1906), American author, poet, and playwright; Ella D. Barrier (1945), American educator; and Eddy Duchin (1951), American pianist, bandleader, and actor.

The record for February 9 runs 226 years deep across 8 entries. Read in sequence, the date stops being a coincidence and starts being a through-line.
