July 21

July 21 is the 203rd day of the year, and the American record for it runs from 1861 to 2024 — a span of 163 years. The entry that anchors it: U.S. President Joe Biden announces he will no longer seek a second term and withdraws from the 2024 election, 2024.

By the middle of the nineteenth century the date carries heavier freight. In 1861, First Battle of Bull Run — at Manassas Junction, Virginia, the first major battle of the war begins and ends in a victory for the Confederate army.

In the postwar nineteenth century the date tracks a nation rebuilding. In 1877, after rioting by Baltimore and Ohio Railroad workers and the deaths of nine rail workers at the hands of the Maryland militia, workers in Pittsburgh, Pennsylvania, stage a sympathy strike that is met with an assault by the state militia.

The postwar entries show a nation both expanding and contesting itself. In 1959, Elijah Jerry "Pumpsie" Green becomes the first African-American to play for the Boston Red Sox, the last team to integrate. He came in as a pinch runner for Vic Wertz and stayed in as shortstop in a 2–1 loss to the Chicago White Sox. The same year, NS Savannah, the first nuclear-powered cargo-passenger ship, is launched as a showcase for Dwight D. Eisenhower's "Atoms for Peace" initiative. Ten years on, in 1969, Apollo program — at 02:56 UTC, astronaut Neil Armstrong becomes the first person to walk on the Moon, followed 19 minutes later by Edwin "Buzz" Aldrin.

Closer to the present, the date is still accumulating. In 2010, U.S. President Barack Obama signs the Dodd–Frank Wall Street Reform and Consumer Protection Act. A year later, in 2011, NASA's Space Shuttle program ends with the landing of Space Shuttle Atlantis on mission STS-135 at NASA's Kennedy Space Center. Then, in 2024, U.S. President Joe Biden announces he will no longer seek a second term and withdraws from the 2024 election, endorsing Vice President Kamala Harris as she launches her own presidential campaign.

The date is also a birthday. Among the Americans born on July 21: C. Aubrey Smith (1863), English-American cricketer and actor; Howie Shanks (1890), American baseball player; Sophie Bledsoe Aberle (1896), American anthropologist, physician and nutritionist; Sara Carter (1898), American singer-songwriter; and Hart Crane (1899), American poet.

July 21 is also a date of endings. Among the Americans who died on it: Sam Bass (1878), American outlaw; Hiram Walden (1880), American general and politician; Nelson Dewey (1889), American lawyer and politician, 1st Governor of Wisconsin; and Robert G. Ingersoll (1899), American soldier, lawyer, and politician.

The date carries formal observance as well — Belgian National Day (Belgium). 8 entries, 163 years, one square on the calendar. July 21 is a reminder that history is experienced as an ordinary day before it is remembered as a date.
