Taco Bell made history in 2024 when it secured National Day Calendar’s official blessing to move National Taco Day permanently to the first Tuesday of October. (Previously, the spicy day was always celebrated on October 4.) This year, National Taco Day falls on Tuesday, October 6, 2026. And Taco Bell is partnering with Duolingo to celebrate the day in a big way!
