Black Friday itself ends at 11:59 p.m. local time on Black Friday, but most “Black Friday sales” now run through the following Monday, known as Cyber Monday, and some deals continue a few days beyond that.

Official end vs sales period

• Officially, Black Friday is just the fourth Friday of November and ends at midnight that day.

• In practice, many retailers advertise Black Friday deals from at least the start of that week and keep them live through the weekend into Cyber Monday.

Typical retailer behavior

• A large number of brands end their main Black Friday/Cyber Monday promotions at 11:59 p.m. on Cyber Monday, which is the Monday immediately after Black Friday.

• Some companies extend discounts into “Cyber Week,” often running offers until around the end of that week or the first days of December, though selection and stock can drop quickly.

What this means for you

• If you see a specific deal you like, plan as if it will end by the end of Cyber Monday to avoid missing it.

• For a particular store, check its sale banner or terms; big retailers like Amazon and others often show the exact end date for their Black Friday or “Black Friday Week” events on their sites.
