How people usually talk about “when is March Madness?”

When fans say “when is March Madness?” , they usually mean one of three things:

  • When the bracket drops (Selection Sunday in mid‑March).
  • When games actually start (First Four or First Round a couple of days later).
  • The overall window, which typically runs from mid‑March through the first week of April every year.

For 2026, if you just want to block your calendar, think “March 15 through April 6.”
