Earth, Wind & Fire Day

It all comes down to three and a half minutes of pure sunshine. “September,” released by Earth, Wind & Fire in 1978, opens with the most famous date in pop music: “Do you remember the 21st night of September?” The song was written by Maurice White and Al McKay with songwriter Allee Willis, whom White had invited to co-write for the band. According to Willis, she arrived at the studio the day after White’s invitation to find the band had just written the happiest-sounding intro in the world, and the date was chosen the fun way. As she told NPR in 2014, they tried every date, “the first, the second, the third, the fourth,” and the one that felt best was the 21st. It simply sang better than all the others. There was, she confessed, no deeper significance. Sorry.

Or maybe there was a secret after all. In a 2026 documentary about the band directed by Ahmir “Questlove” Thompson, a new revelation surfaced: Maurice White’s longtime partner Marilyn White said September 21 was the expected arrival date of their son, Kahbran, who ended up being born early in August instead. So the most joyful date in funk may have started as a father’s private hope, even if the official story remains that it just sounded right. Either way, the 21st stuck, and generations of listeners have been ba-dee-ya-ing ever since.

The band behind the song is every bit as legendary as the date. Earth, Wind & Fire was formed in Chicago in 1969 by bandleader and percussionist Maurice White, after an earlier incarnation called The Salty Peppers. The cosmic new name came from White’s zodiac sign, Sagittarius, whose element is fire, and the group headed west with a bold new sound. What followed was a kaleidoscopic fusion of R&B, soul, funk, jazz, disco, pop, rock, dance, Latin, and traditional African music, delivered with an energetic stage presence and a horn section for the ages.

The hits piled up through the seventies and beyond: “Shining Star,” “That’s the Way of the World,” “Boogie Wonderland,” “Let’s Groove,” “Serpentine Fire,” and their joyful cover of the Beatles’ “Got to Get You Into My Life.” They were among the first African American acts to sell out major arenas worldwide and cross over to mainstream pop audiences while keeping the respect of jazz and R&B communities. In 2000, they were inducted into the Rock and Roll Hall of Fame. Maurice White, the visionary at the center of it all, passed away in February 2016 at age 74 after living with Parkinson’s disease, but the music never stopped.

Somewhere along the way, September 21 became a holiday. Comedian Demi Adejuyigbe deserves much of the credit: for several years he posted a video of himself dancing to “September” every September 21st, building to a spectacular eight-minute mini-movie in 2021 that featured shout-outs from the band themselves. Memes, playlists, and radio marathons followed, and in 2019 the Los Angeles City Council made it official in the band’s adopted hometown, declaring September 21 “Earth, Wind & Fire Day,” with band members Ralph Johnson, Philip Bailey, and Verdine White on hand for the honor. National Day Calendar lists the day every September 21, and the internet does the rest.

That is the magic of this particular holiday. There is no brand behind it and nothing to buy, just millions of people vibing on the same groove at the same time, once a year, as a way of saying good morning. So turn it up. The 21st night of September only comes once a year, and it deserves to be remembered loudly.

Musically, “September” is a masterclass in joy. Al McKay’s deceptively simple four-chord progression drives the whole track, Verdine White’s bassline struts underneath with unmistakable swagger, and the Phenix Horns add layer upon layer of brightness, all wrapped in lush string arrangements. It is funk, soul, and R&B blended so smoothly that it never loses energy, the kind of production that makes it nearly impossible to sit still. No wonder the song keeps showing up everywhere: it closed out “Night at the Museum” in 2006, lit up the animated hit “Trolls” in 2016, and soundtracks weddings, commercials, and parties to this day.

And then there are the memes, which have become a holiday tradition of their own. Every September 21st, social media fills with screenshots of Maurice White singing in the “September” music video, each one captioned with some version of the inevitable question. People belt out the ba-dee-ya in the street, DJs build entire sets around the groove, and radio stations lean into the marathon. It is all gloriously silly and completely sincere, a shared annual ritual built from three and a half minutes of music. Few songs get a spot on the calendar. This one earned it.
