According to Chatgpt,


Chatgpt agrees with you.

The term "Sports Equinox" is used to describe a day in late October when all four major U.S. sports leagues—NFL, NBA, NHL, and MLB—have games scheduled on the same day. This rare occurrence typically happens in the fall when all the seasons overlap briefly, and it's a big event for sports fans since it's one of the few days where fans can watch all four leagues in action.

But then again, Chatgpt could have farmed the answer from here since I asked after you wrote it.

EDIT: When I asked, "are there other terms people have used?" It replied with the following:

Yes, besides "Sports Equinox," people sometimes call this event by other names, though they're less common. Here are a few variations:

1. "Super Sports Saturday/Sunday" – When it falls on a weekend, people might refer to it this way.
2. "Quad Sports Day" – Some fans emphasize the four-sport combination by calling it "Quad Sports Day" or "Quadruple Sports Day."
3. "Mega Sports Day" – This general term captures the magnitude of having all four leagues play on the same day.
4. "Sports Mega-Overlap" – A few fans use this to describe the unusual overlap of all four leagues.

Each term highlights the excitement and rarity of this confluence in the sports calendar.
