Over the past several days, a comedian named Demi Adejuyigbe has been making increasingly elaborate videos in which she pries open a curtain to reveal that it's September 21. As the confetti shoots, she declares that it's Earth, Wind & Fire Day, and that today is "do you remember the 21st night of september meaning."
This is all in response to a viral meme centered around a line from the 1978 Earth, Wind, and Fire song September that begins, "Do you remember the 21st night of September?" While it might seem like a trivial matter, the date has actually become quite meaningful for some people, including many who use it as a reminder to stay positive. Others take it as a sign to party hard and stay true to themselves.
The song is a classic, and it's not uncommon to hear it being played at parties or on the radio. However, the reason why the band chose to reference the specific date has always been a mystery. Many people have speculated that the choice had to do with the autumnal equinox, but Allee Willis, who co-wrote the track with bandleader Maurice White, has revealed that it was simply a matter of musical taste.
In a 2014 interview with NPR, Willis stated that the band had gone through all the possible dates in the opening phrase and that they ultimately settled on September 21 because it was the one that sounded the best. She also went on to explain that the rest of the lyrics in the song—including the nonsensical ba-dee-ya phrase—were simply chosen based on how they sounded together.
