About September 13

September 13 feels tailor-made for the curious and the mischievous—and not by accident. It's the birthday of Roald Dahl, the British author who gave children everywhere permission to revel in the grotesque and glorious. Celebrated across the UK, Africa, and Latin America, Roald Dahl Day honors a storyteller who understood that kids rarely want their tales sanitized. He'd have appreciated the irony that his birthday shares the calendar with National Defy Superstition Day—Dahl never met a rule he didn't want to bend.

This date also carries an extraordinary musical coincidence. In 1814, Francis Scott Key watched British ships fail to capture Baltimore and jotted down a poem that became the United States national anthem. Exactly 171 years later, in 1985, Nintendo released Super Mario Bros. in Japan, launching a theme song as universally recognizable as any anthem. From a dawn bombardment at Fort McHenry to a plumber racing through the Mushroom Kingdom, September 13 has soundtracked revolutions both martial and digital.

It's also a day of handshakes and hard-won steps forward. In 1993, Yitzhak Rabin and Yasser Arafat clasped hands at the White House after signing the Oslo Accords, offering a fleeting glimpse of Middle East peace. On the same date in 1933, Elizabeth McCombs became the first woman elected to New Zealand's Parliament, and in 1948 Margaret Chase Smith won a U.S. Senate seat, becoming the first woman to serve in both chambers of Congress. Virgo energy—methodical, determined, quietly revolutionary—runs through every one of these moments.
