“Do you recall the 21st night of September?” Earth, Wind & Fire first posed this question in 1978. Over the years—thanks in large part to writer and comedian Demi Adejuyigbe’s viral tributes to the song and the date—September 21st has evolved into what many consider the internet’s unofficial holiday, often referred to as “the most significant day of the year.”
To celebrate this special day, here are 12 notable events that have taken place on September 21st. By the end, you’ll not only remember the 21st night of September—you’ll understand why it’s worth celebrating.
