Amazon’s main Black Friday deals usually run for about 10–12 days, starting roughly a week before Black Friday and continuing through Cyber Monday (and sometimes through December 1).

Typical duration

  • In recent years, Amazon has turned “Black Friday” into a longer event that starts around November 20 and runs through Cyber Monday, often ending December 1.
  • For example, Amazon’s official 2025 Black Friday and Cyber Monday “events” were announced to run from November 20 through December 1.

How daily deals work

  • Some discounts last the entire event (or until items sell out), while others are 24‑hour “Today’s Deals” or short Lightning Deals that only run for a few hours.
  • This means the overall Black Friday window is 10–12 days, but specific products may only be on sale for a small part of that time.

What to expect going forward

  • Retail analysts and Amazon‑focused marketers expect Amazon to keep using an extended 11–12 day “Black Friday/Cyber Monday” corridor rather than a single‑day sale, with dates shifting slightly each year around Thanksgiving through Cyber Monday.
  • You can assume most major Black Friday deals will be live sometime between roughly November 20 and Cyber Monday, with new rounds of offers dropping daily.

TL;DR: If you are asking “how long are Black Friday deals on Amazon?” plan on about a week and a half of deals, but check early (around November 20) and often, because the best Lightning Deals can disappear within hours.
