Official set times just dropped. Aftershock 2026 locks Discovery Park Thursday through Sunday, October 1–4 — and the timed schedule is now live across five stages with 140+ set windows. News is the alert; the lineup hub plus the official Aftershock schedule / app stay canonical as times move.
Headliner windows (subject to change): Thursday night My Chemical Romance owns the Aftershock Stage ~8:25–9:55p. Friday Limp Bizkit closes ~9:45–11:00p. Saturday Pierce The Veil ~9:25–10:55p. Sunday Tool seals the weekend ~8:25–9:55p. Under card stacks deep every day — map your conflicts on the hub before you commit a stage.
How to use it. Treat this post as the drop notice, not a printable grid. Festival schedules shift; stages collide; weather and production move sets. Bookmark the Aftershock 2026 event page, keep the day-by-day lineup open, and verify live times on the official Aftershock schedule page / festival app before you walk Garden Highway. Passes, first-year Cal Expo camping, and Park & Ride still sell separately if you have not locked your plan.
Set times are live — grab your days, pick your stages, and ride the five-stage war zone October 1–4 in Sacramento.
