When you ask a search engine [when is Black Friday], most search engines will give you the day and date, i.e. Friday, November 28.
But with one interesting query on Yahoo Search, Yahoo is giving you a countdown widget to when Black Friday is.
Spotted somehow by Sunny K. Ujjawal and posted on Google+, a search in Yahoo for ["American Tourists can Enjoy Thanksgiving in London with"] brings back the countdown widget.
I tried bringing it up for searching in Yahoo for "black friday is in" or "countdown to black friday" and other alternatives, but none of the logical queries return this widget.
I find it incredibly interesting that this obscure, long, query returns it.
