- The Kentucky Derby, held in Louisville, Kentucky, is traditionally on the first Saturday in May. The 2026 Kentucky Derby is scheduled for Saturday, May 2nd, 2026.
- The Epsom Derby, the original and classic "Derby" held in England, will take place on Saturday, June 6th, 2026.
- The Victoria Derby in Australia occurs during the Melbourne Spring Racing Carnival, with the 2025 Victoria Derby Day set for Saturday, November 1st, 2025.
Therefore, "Derby Day" most commonly refers to the first Saturday in May for the Kentucky Derby, but also to other dates for other major Derbies worldwide. For the most widely recognized Kentucky Derby, the next Derby Day will be on Saturday, May 2nd, 2026.
