Black Friday & Cyber Monday Countdown

A live countdown to both dates, calculated from the rule that actually defines them — not looked up from a fixed list.

How these dates are actually defined

Black Friday is always the day immediately following US Thanksgiving — the 4th Thursday of November, per the US federal holiday calendar — which makes it always a Friday, but the calendar date itself moves within a roughly week-wide range each year. Cyber Monday is simply the following Monday, a newer, purely retail-invented date (coined in 2005) with no historical or governmental basis at all — it exists purely because it was the next convenient shopping-focused day after a long weekend.

Neither is an official public holiday

Unlike Thanksgiving itself, neither Black Friday nor Cyber Monday is a federal holiday — many people are simply off work because Thanksgiving Thursday often gets paired with the Friday as a company-granted long weekend, not because Friday itself is any kind of statutory holiday.
