January 21

January 21 is the 21st day of the year, and the American record for it runs from 1919 to 2017 — a span of 98 years. The entry that anchors it: War on drugs, 1999.

As the country moved into the modern age, the date accumulated new kinds of firsts. In 1919, the First Dáil convened at the Mansion House in Dublin and adopted a declaration of independence calling for the establishment of the Irish Republic.

In the postwar decades the date belonged to a nation of enormous reach and unfinished arguments. In 1954, the first nuclear-powered submarine, the USS Nautilus, is launched in Groton, Connecticut by Mamie Eisenhower, the First Lady of the United States. Then, in 1968, Vietnam War — the People's Army of Vietnam attacked Khe Sanh Combat Base, a U.S. Marines outpost in Quảng Trị province, South Vietnam, starting the Battle of Khe Sanh.

In living memory, the date has kept adding to the record. In 1997, the U.S. House of Representatives voted 395–28 to reprimand Newt Gingrich for ethics violations, making him the first Speaker of the House to be so disciplined. Two years on, in 1999, War on drugs — in one of the largest drug busts in American history, the United States Coast Guard intercepts a ship with over 4,300 kilograms (9,500 lb) of cocaine on board. Five years on, in 2004, NASA's MER-A (the Mars Rover Spirit) ceases communication with mission control. The problem lies in the management of its flash memory and is fixed remotely from Earth on February 6. Then, in 2017, over 400 cities across America and 160+ countries worldwide participate in a large-scale women's march, including in Portland, on Donald Trump's first full day as President of the United States. The same year, millions of people participated in the Women's March in Washington, D.C., and around the world to advocate for legislation and policies on human rights and other issues.

The date is also a birthday. Among the Americans born on January 21: Ethan Allen (1738), American general; John C. Frémont (1813), American general, explorer, and politician, 5th Territorial Governor of Arizona; Horace Wells (1815), American dentist; Stonewall Jackson (1824), American general; and Francis Gailey (1882), Australian-American swimmer.

January 21 is also a date of endings. Among the Americans who died on it: David Ker (1805), Irish-American educator and judge; Josiah Hornblower (1809), American engineer and politician; Calixa Lavallée (1891), Canadian-American lieutenant and composer; and Elisha Gray (1901), American engineer, co-founded Western Electric.

The date carries formal observance as well — National Hugging Day (United States). Taken together, the 8 entries on January 21 span 98 years of American life. A date is an arbitrary container, but what fills it is not arbitrary at all.
