Black Friday is a sale that takes place in November the day after Thanksgiving and Cyber Monday immediately after the holiday weekend. Originally popular only in the U.S., the tradition has eventually spread around the world. These sales are often blended together so that shopping events span the entire weekend.
In 2025, Black Friday starts at midnight on November 27 and runs through November 29, followed by Cyber Monday on December 1. According to research,
up to 45% of people start shopping for New Year's gifts as early as November. At the same time,
more than half of shoppers make at least one impulse purchase, even if they've prepared a list in advance.
Here are practical tips to help you prepare your online store for Black Friday and Cyber Monday, avoid losing customers, and suggest what to do after the campaign ends.
