Hash Bash has been a fixture in Ann Arbor since the early 1970s. The event draws visitors from across Michigan and beyond to the Diag, the central gathering space on the U-M campus.
Event Basics
The 2026 edition takes place on April 4, 2026 — the first Saturday of April, as is tradition. The Diag is the main venue, with crowds typically gathering from mid-morning through the afternoon.
What to Expect
The event is informal and community-focused. There are often speakers, music, and vendors. The atmosphere is celebratory and relaxed. Many attendees come prepared for the weather and a day of walking around campus and downtown Ann Arbor.
