F1’s 2026 Americas Dates: Race Day or Full Weekend?

United States: the weekend starts before race day

Formula 1 lists the United States weekend for October 23–25 in its 2026 calendar. The FIA places the Grand Prix at Circuit of the Americas on October 25. These entries answer different questions: the date range identifies the event weekend, while the single date identifies the race. Using the race date alone would leave out the opening part of the listed weekend. [1] [2]

Mexico and Brazil: match the country and city labels

The Formula 1 calendar labels Mexico’s weekend October 30–November 1. The FIA names the Mexico City Grand Prix, lists Autodromo Hermanos Rodriguez and gives November 1 as the race date. The month changes within the weekend, so an October-only calendar note would miss its final day. [1] [2]

Formula 1 then lists Brazil for November 6–8. The FIA’s corresponding São Paulo Grand Prix is dated November 8 at Interlagos. Matching the country label to the Grand Prix name helps a reader recognize the same round across the two calendar formats. [1] [2]

Las Vegas: keep the span and the single date together

Formula 1 lists Las Vegas for November 19–21; the FIA gives November 21 as its Grand Prix date. Here, too, the single race date is the final day of the listed span. Keep both entries when making a calendar note: the event range provides context, and the race date answers the narrower race-day question. A weekend span alone does not identify the time of each session. [1] [2]
