How did Black Friday begin?

Black Friday originated in America. 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 – usually 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 a few years ago. Between 2010 and 2013, Black Friday gradually built up momentum in the UK. In 2014, Black Friday was 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. 

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.
