How Many Days Until Cyber Monday 2027?

Cyber Monday 2027 is Monday, 29 November 2027

There are 467 days between 19 August 2026 and Cyber Monday 2027, which falls on Monday, 29 November 2027. That is 66 weeks and 5 days, or 318 working days once Saturdays, Sundays and the US federal holidays in between are taken out — the figure that matters if you are counting delivery lead time or a work schedule rather than sleeps. The date is 2027-11-29 in ISO form and 11/29/2027 in the US format, it falls in ISO week 48 of 2027, and it is day 333 of 365.

How the date of Cyber Monday is decided

The Monday after Thanksgiving, between 26 November and 2 December.

That makes it a computed date: there is no fixed day and no simple weekday rule, so it has to be worked out from a formula or a calendar of its own each year. In 2027 it works out as Monday 29 November.

Cyber Monday is an observance rather than a federal holiday. Offices, banks and schools stay open unless an individual employer chooses otherwise, and it counts as an ordinary business day in every calculator here. Only the eleven federal holidays are treated as non-working days — the list and the reasoning are on the holiday sources page.

Cyber Monday in the years after 2027

Both the date and the weekday move, because the rule is not tied to either.

Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including how we count the 318 working days above.
