January 6

January 6 is the 6th day of the year, and the American record for it runs from 1912 to 2021 — a span of 109 years. The entry that anchors it: Supporters of then-outgoing U.S. president Donald Trump attack the United States Capitol to disrupt certification of the 2020 presidential election, 2021.

As the country moved into the modern age, the date accumulated new kinds of firsts. In 1912, New Mexico is admitted to the Union as the 47th U.S. state. Then, in 1941, during his State of the Union address, U.S. president Franklin D. Roosevelt presented his Four Freedoms as fundamental freedoms that all people ought to enjoy.

In the postwar decades the date belonged to a nation of enormous reach and unfinished arguments. In 1967, Vietnam War — United States Marine Corps and ARVN troops launch "Operation Deckhouse Five" in the Mekong River delta. Two years on, in 1969, Allegheny Airlines Flight 737 crashes in Lafayette Township, McKean County, Pennsylvania, United States, killing 11. Five years on, in 1974, in response to the 1973 oil crisis, the United States implements the Emergency Daylight Saving Time Energy Conservation Act, switching to permanent daylight saving time for a trial period.

In living memory, the date has kept adding to the record. In 1994, U.S. figure skater Nancy Kerrigan is attacked and injured by an assailant hired by her rival Tonya Harding's ex-husband during the U.S. Figure Skating Championships. Then, in 2005, a train collision in Graniteville, South Carolina, United States, releases about 60 tons of chlorine gas. Then, in 2021, Supporters of then-outgoing U.S. president Donald Trump attack the United States Capitol to disrupt certification of the 2020 presidential election, resulting in five deaths and evacuation of the U.S. Congress.

The date is also a birthday. Among the Americans born on January 6: James Madison Porter (1793), American lawyer and politician, 18th United States Secretary of War; Jedediah Smith (1799), American hunter, explorer, and author; Joseph Pitty Couthouy (1808), American conchologist and paleontologist; Charles Sumner (1811), American lawyer and politician; and Clarence King (1842), American geologist, mountaineer, and critic.

January 6 is also a date of endings. Among the Americans who died on it: Richard Henry Dana Jr. (1882), American lawyer and politician; Theodore Roosevelt (1919), American colonel and politician, 26th President of the United States; Devil Anse Hatfield (1921), American Confederate guerrilla and leader of the Hatfield clan during the Hatfield-McCoy feud; and Alvin Kraenzlein (1928), American hurdler and long jumper.

Read end to end, January 6 is less a list than a cross-section: 8 entries that happen to share a square on the calendar, separated by as much as 109 years. The coincidence is arbitrary; the accumulation is not.
