The Amazon Big Spring Sale ends on March 31, 2026 at 11:59 p.m. Pacific Time (which is 2:59 a.m. Eastern Time on April 1).

Quick Scoop

  • Official sale dates: March 25–31, 2026.
  • End time: 11:59 p.m. PDT on March 31, 2026.
  • Some “early deals” started before March 25 and may continue briefly after, but the main Big Spring Sale promos stop at that March 31 cutoff.

Why the timing matters

Different outlets that covered the event all agree that the 2026 Big Spring Sale is a seven‑day event ending the night of March 31 in Pacific Time. That means if you’re in a later time zone (like Eastern), the sale effectively runs into the very early hours of April 1 for you.

Some deal sites also note that a few discounts or coupons may linger or reappear as regular promotions, but they are no longer part of the official Big Spring Sale once that deadline passes.

Forum-style takeaway

If you’re asking “when does the Big Spring Sale on Amazon end?” and you want to squeeze in last‑minute purchases, treat 11:59 p.m. PDT on March 31, 2026 as your hard stop and shop a bit earlier to avoid missing Lightning Deals or low‑stock items.

TL;DR: The Amazon Big Spring Sale 2026 officially ends March 31, 2026 at 11:59 p.m. Pacific Time; after that, any remaining discounts are just normal or leftover deals, not part of the event.
