October 1 is trending in large part because people are using the date as a signifier for the arrival of fall. While there are other fall days that have held this mantle over the years, including September 21, this year, TikTok users have decided that October 1 is the day to celebrate fall.
In particular, the trend involves setting your video to the song "we fell in love in october" by girl in red.

The song's chorus has become a focal point for these videos, in part because of its chorus, which includes the lyrics. "My girl, my girl, my girl / You will be my girl / My girl, my girl, my girl / You will be my world / My world, my world, my world / You will be my girl."
This simple chorus has left many in the mood for love, whether that means posting a tribute to your girlfriend or pining for the kind of relationship that would inspire these kinds of lyrics.
It's a wonderful confluence of two persistent trends on TikTok, one focused on the fall and the other focused on relationships. Of course, some people are also using the song to express their excitement for other elements of fall, whether that means the clothes or the decor.
The song is wistful all on its own, but girl in red has long had a special place in the heart of many TikTok users.
