March 18

March 18 is the 78th day of the year, and the American record for it runs from 1865 to 2019 — a span of 154 years. The entry that anchors it: American Civil War, 1865.

Through the nineteenth century the date gathered the tensions that would define the era. In 1865, American Civil War — the Congress of the Confederate States adjourns for the last time.

As the country moved into the modern age, the date accumulated new kinds of firsts. In 1925, the deadliest tornado in U.S. history spawned in Missouri and traveled more than 219 miles (352 km) across Illinois and Indiana, leaving one of the longest continuous tornado tracks ever recorded. The same year, the 1925 Tri-State tornado hits the Midwestern states of Missouri, Illinois, and Indiana, killing 695 people. Then, in 1942, the War Relocation Authority is established in the United States to take Japanese Americans into custody.

In the postwar decades the date belonged to a nation of enormous reach and unfinished arguments. In 1968, Gold standard — the U.S. Congress repeals the requirement for a gold reserve to back US currency. A year later, in 1969, Vietnam War — the United States began secretly bombing the Sihanouk Trail in Cambodia, used by communist forces to infiltrate South Vietnam. A year later, in 1970, U.S. postal workers began an eight-day strike after Congress raised their wages by only 4 percent despite increasing its own pay by 41 percent.

In living memory, the date has kept adding to the record. In 2019, Syrian civil war — the U.S. Air Force carried out an airstrike in al-Baghuz Fawqani, killing as many as 80, a disputed number of whom were civilians.

The date is also a birthday. Among the Americans born on March 18: John C. Calhoun (1782), American lawyer and politician, 7th Vice President of the United States; Francis Lieber (1798), German-American jurist and philosopher; John Plankinton (1820), American businessman, industrialist, and philanthropist; Grover Cleveland (1837), American lawyer and politician, 22nd and 24th President of the United States; and Kicking Bear (1845), Native American tribal leader.

March 18 is also a date of endings. Among the Americans who died on it: Johnny Appleseed (1845), American gardener and missionary; Matilda Joslyn Gage (1898), American author and activist; Henry Janeway Hardenbergh (1918), American architect, designed the Plaza Hotel; and Jean Leon Gerome Ferris (1930), American painter.

Read end to end, March 18 is less a list than a cross-section: 8 entries that happen to share a square on the calendar, separated by as much as 154 years. The coincidence is arbitrary; the accumulation is not.
