What is Black Friday and why did it become a whole month?

Black Friday is the discount day on the Friday after American Thanksgiving in late November. In 2026, it falls on November 27. Originating in the United States, it reached Brazil through online commerce and is now one of the year’s largest internet sales campaigns.
Customers enter November expecting discounts. Unprepared businesses sell less or at a loss. Those preparing in October choose offers, concessions and exclusions.
Why did Friday become a month?

Competition outgrew one day. Large retailers bring offers forward to secure customers, while customers compare prices from early November. There are warm-ups, Black Week, Black November and the Friday itself.
For small companies, two effects follow. Peaks spread out, so choose your day or week rather than compete all month, and announce it beforehand. Customers also arrive skeptical after seeing October price increases disguised as November reductions. Fake discounts cause Procon complaints; see the reference-price rules.
What changes for small businesses?
Margins change: 50% discounts on 30%-margin products create losses. Operations change: orders arrive in batches, stock runs out and deliveries delay. Customer service changes: WhatsApp messages multiply beyond manual replies.
A natural-cosmetics store with two fast-selling and eight slow-moving products need not discount everything by 40%. It bundles two bestsellers with one slow item and discounts the set 15%, moving old stock without destroying annual margins.
You still have weeks to decide. October’s job is calculating, choosing offers and checking website, payment and delivery capacity.

Frequently asked questions
When is Black Friday 2026?
Friday, November 27, 2026. Most stores advertise in preceding weeks and extend through the following Monday.
Must small businesses participate?
No. Without discount margins, staying out is better than losing money. Free shipping, gifts and bundles offer alternatives to price cuts.
Does Black Friday work for services?
Yes, adapted. Defined packages with special terms for closing by a deadline work better than pure immediate discounts.
