What is Cyber Monday?
Cyber Monday is the Monday after American Thanksgiving, four days later, which can land it in the first days of December. The National Retail Federation coined the term in 2005 after noticing that online orders spiked when people got back to fast office connections after the holiday weekend. Home broadband has removed the original reason, but the date stuck and is now one of the largest online shopping days of the year. It is calculated here from the fourth Thursday in November.
The next one falls on Monday, 30 November 2026, and this page counts down to the midnight that starts it in whatever time zone your browser reports. For a date of your own, the deadline countdown takes any target and tracks progress against it.
