June 19

June 19 is the 171st day of the year, and the American record for it runs from 1785 to 2005 — a span of 220 years. The entry that anchors it: Over two years after the Emancipation Proclamation, 1865.

In the founding decades, the date sat close to the business of building a republic. In 1785, the Boston King's Chapel adopts James Freeman's revised prayer book, without the Nicene Creed, establishing it as the first Unitarian congregation in the United States.

Through the nineteenth century the date gathered the tensions that would define the era. In 1838, the Maryland province of the Jesuits contracted to sell 272 slaves to buyers in Louisiana in one of the largest slave sales in American history. Eight years on, in 1846, the first officially recorded baseball game in U.S. history using modern rules was played in Hoboken, New Jersey, with the "New York Nine" defeating the New York Knickerbockers 23–1. Then, in 1862, President Abraham Lincoln signs the Territorial Slavery Act of 1862, which prohibits slavery in all current and future United States territories. Three years on, in 1865, over two years after the Emancipation Proclamation, slaves in Galveston, Texas, United States, are officially informed of their freedom. The anniversary was officially celebrated in Texas and other states as Juneteenth. On June 17, 2021, Juneteenth officially became a federal holiday in the United States.

As the country moved into the modern age, the date accumulated new kinds of firsts. In 1939, American baseball player Lou Gehrig was diagnosed with amyotrophic lateral sclerosis, now commonly known in the United States as "Lou Gehrig's disease"

In the postwar decades the date belonged to a nation of enormous reach and unfinished arguments. In 1964, the Civil Rights Act of 1964 is approved after surviving an 83-day filibuster in the United States Senate.

In living memory, the date has kept adding to the record. In 2005, Only six race cars competed in the United States Grand Prix at the Indianapolis Motor Speedway in Indianapolis, Indiana, after all the Michelin-shod entrants were withdrawn due to safety concerns.

The date is also a birthday. Among the Americans born on June 19: Francis Johnson (1776), American lawyer and politician; Joseph Earl Sheffield (1793), American businessman and philanthropist; William H. Webb (1816), American shipbuilder and philanthropist, founded the Webb Institute; Mary Tenney Gray (1833), American editorial writer, club-woman, philanthropist, and suffragette; and Mary Sibbet Copley (1843), American philanthropist.

June 19 is also a date of endings. Among the Americans who died on it: Benjamin Tasker Sr. (1768), American soldier and politician, 10th Colonial Governor of Maryland; Nathanael Greene (1786), American general; Sarah Rosetta Wakeman (1864), American soldier; and Grace Abbott (1939), American social worker and activist.

The date carries formal observance as well — Juneteenth (United States). Taken together, the 8 entries on June 19 span 220 years of American life. A date is an arbitrary container, but what fills it is not arbitrary at all.
