Buffalo Grove Days is the Chicago suburb's Labor Day festival, five days from Thursday night to Monday afternoon at Mike Rylko Community Park, with a carnival, cover and tribute bands on the park's amphitheater stage and a parade down Buffalo Grove Road. More than 49,000 people came through over the five days in 2023, and admission is free for everyone. This is a hometown crowd of families. The 2026 program filled Saturday and Sunday with face painting, a petting zoo, a police K9 demonstration, a dog show judged on best costume, best trick and waggiest tail, a bags tournament and a Business and Craft Fair. The main stage carried 2026 headliners including The Brothers Gibb, 16 Candles and Rod Tuffcurls and the Bench Press. The festival reaches the whole village before anyone arrives. The 2026 parade carried more than 60 community groups, businesses and organizations, the Rotary duck race streamed live on the Buffalo Grove Rotary Facebook page, and the Daily Herald previewed the festival with a full schedule in 2024, 2025 and 2026. Local and regional brands show up every year. Logos on the festival site have included ComEd, Ozinga, Dick's Sporting Goods, Bowlero, Civiltech and Ankin Law, Hatch sponsored the 2026 beer tent cups, and McDonald's, Walgreens and Kona Ice supported the 2026 Fun and Food lunch for residents with disabilities. The good goes back to town too: the 2023 festival sent $21,815 to the Buffalo Grove Community Foundation for grants to local nonprofits. The Community Partner package, at $16,500, gives your brand high-visibility signage on the festival grounds, a logo in festival print materials, a place on the bgdays.com sponsor page and recognition on the festival's social media.
