The last few months of the year are often called the Golden Quarter for retailers.

This is the period in the year in which they often earn the most money.

It was thought that the name Black Friday comes from when retailers move from the red to the black.

When talking about money, a business can be in the red if they owe money or have not made a profit.

A business is described as being in the black when they have no money owed or if they are making a profit.

However, this is not where the name for Black Friday comes from.

The phrase Black Friday was first used by police officers in the city of Philadelphia to describe the chaos of the Friday after Thanksgiving, as people rushed to the shops to buy Christmas presents.

In the 1980s, the phrase was used in a more positive way by retailers and businesses, suggesting it was the day they started to turn a profit.
