Everything you need to know, including how the sale works, what date Black Friday falls on this year, and how it all started.

When is Black Friday 2021?

This year, Black Friday falls on Friday 26 November 2021.

However, in recent years many retailers have begun offering deals from the start of the month, leading some to rename it 'Black November'.

In this guide, we'll explain how Black Friday works. 

We've also got links to best Black Friday deals stories from last year. We will update these with 2021 deals as soon as they start launching.

How did Black Friday begin?

Black Friday originated in the USA. As Thanksgiving always falls on the fourth Thursday in November, the following Friday is often observed as an unofficial holiday. 

Because many people are off work, shops drop prices – historically for one day only – to start the Christmas season. 

UK shops have since caught on to this trend and it was brought across the pond over a decade ago. Between 2010 and 2013, Black Friday gradually built up momentum in the UK. In 2014, Black Friday became the peak pre-Christmas online sales day and online retailers haven't looked back since.

When is Cyber Monday 2021?

Cyber Monday is always the Monday directly following Black Friday. Cyber Monday 2021 falls on 29 November this year.

The tradition first started in 2005, when the National Retail Federation, an American trade association, noticed a spike in online sales the Monday after Thanksgiving. 

According to retail news site Charged, Cyber Monday 2020 was the most successful digital sales day ever to have taken place (it has since been beaten by Amazon Prime Day 2021).
