What Is Black Friday?

Black Friday is around the corner. We would like to talk about this crazy shopping day.
Black Friday was originally an American tradition, it is the Friday following Thanksgiving Day in the United States, often regarded as the beginning of the Christmas shopping season. Retailers offer massive discounts on a masses of products in an attempt to persuade you to spend your hard earned in the run-up to Christmas. But UK retailers have jumped on the bandwagon in recent years so bargain hunters over here get the chance at some festive deals. It has routinely been the busiest shopping day of the year since 2005, although news reports, which at that time were inaccurate, have described it as the busiest shopping day of the year for a much longer period of time.

When is Black Friday?And what time will it start?

This year Black Friday will happen on the Friday following Thanksgiving Day (fourth Thursday of November). However, In recent years, almost all the retailers have opened early and offered promotional sales to kick off the holiday shopping season, similar to Boxing Day sales in many Commonwealth nations. Retailers generally see an upward spike in sales and consider this to be the start of the holiday shopping season. It's common for retailers to offer special promotions and to open early to draw in customers.

Why is it called Black Friday?
Originally, September 24, 1869, was deemed Black Friday. The crash was sparked by gold speculators, including Jay Gould and James Fist, who attempted to corner the gold market. The attempt failed and the gold market collapsed, causing the stock market to plummet. Explanation was made: that retailers traditionally operated at a financial loss ("in the red") from January through November, and "Black Friday" indicates the point at which retailers begin to turn a profit, or "in the black".
Nobody's entirely sure, but most suggestions surround how businesses and retailers detail their finances. Many shops see the biggest profits of the year on Black Friday. Many businesses will detail their gains in black ink (and losses in red ink), hence the name.

Since black day is a big day for shopping. There are many customers wait for this day get products with good budget. Only one day is too short. We have a whole November. And you can have enough time to buy the car GPSand car DVD player car DVD player that you want with much good price.
