What is the Days Until Cyber Monday Calculator?
This tool (for the United States) counts how many days remain until Cyber Monday — the Monday following the Thanksgiving holiday. In the US, Thanksgiving falls on the fourth Thursday of November, so Cyber Monday is always four days later.
How to use it
Enter the target year and today's date. The calculator finds the fourth Thursday of November for that year, adds four days to land on Cyber Monday, then subtracts today's date to give the countdown in whole days.
The formula explained
First we locate the first Thursday of November, then add 21 days to reach the fourth Thursday (Thanksgiving). Adding four more days lands on the following Monday — Cyber Monday. Finally, the difference in days between Cyber Monday and today gives the answer.
$$\text{Days} = \frac{\text{CyberMonday} - \text{Today}}{86400000}$$ $$\text{where}\quad \left\{ \begin{aligned} \text{Thanksgiving} &= \text{4th Thursday of November in } \text{Year} \\ \text{CyberMonday} &= \text{Thanksgiving} + 4 \text{ days} \end{aligned} \right.$$
Worked example
For 2024, November 1 is a Friday. The first Thursday is November 7, so Thanksgiving is November 28. Adding 4 days gives Cyber Monday on December 2, 2024. Counting from November 1, 2024 that is \(31\) days.
FAQ
When is Cyber Monday? It is the Monday immediately after Thanksgiving, four days after the fourth Thursday of November.
Why can Cyber Monday fall in December? When Thanksgiving lands late in November (e.g. Nov 28 or 29), adding four days pushes Cyber Monday into early December.
Is this US-specific? Yes. The Thanksgiving-based date applies to the United States shopping calendar.
