“Natty” in this context almost always means the college football National Championship game (the national title game). Because there are different “natty” games in different sports and years, the exact date depends on which one you mean (e.g., this season’s College Football Playoff title game, next season, etc.). To give you an accurate, up‑to‑date date for “the natty” this year, up to the current day in 2026, external schedule data is needed, and that information is not directly accessible in this chat. If you tell which natty you mean (college football, basketball, another sport, and which year or season), the answer can be narrowed down very precisely using an up‑to‑date schedule source.
