Dio Day 2026 is officially on the calendar.
I-100 is proud to be media sponsor of Dio Day 2026! For more than a decade the Dio Day committee has raised money for the Dio Day Music Scholarship, awarded every year to a Cortland High School student — the same school Ronnie James Dio graduated from.
This year, Dio Day happens Sunday, July 19th, at the Cortland Music Park — a venue we are so excited about. Tons of space, deep Cortland roots, and the perfect place to celebrate Ronnie’s legacy. Camping is available!

We’re excited to announce Dio Day 2026 at our spacious new venue, and we want YOU to be part of the fun! Reserve a booth for just $50 for the entire day. Keep all your profits while connecting with fellow music lovers and enjoying amazing live music.
