Black Friday

Black Friday is the day following Thanksgiving Day in the United States, traditionally the beginning of the Christmas shopping season. On this day, most major retailers open extremely early and offer promotional sales to kick off the holiday shopping season, similar to Boxing Day sales in many Commonwealth Nations. Black Friday is not an official holiday, but many non-retail employers also observe this day as a holiday along with Thanksgiving, giving their employees the day off, thereby increasing the number of potential shoppers. It has routinely been the busiest shopping day of the year since 2005,[1] although news reports, which at that time were inaccurate,[2] have described it as the busiest shopping day of the year for a much longer period of time.[3]
The day's name originated in Philadelphia, where it originally was used to describe the heavy and disruptive pedestrian and vehicle traffic which would occur on the day after Thanksgiving.[4][5] Use of the term started before 1961 and began to see broader use outside Philadelphia around 1975. Later an alternative explanation began to be offered: that "Black Friday" indicates the point at which retailers begin to turn a profit, or are "in the black".[4][6]
For many years, it was common for retailers to open at 6:00 a.m., but in the late 2000s many had crept to 5:00 or even 4:00. This was taken to a new extreme in 2011, when several retailers (including Target, Kohls, Macy's, Best Buy, and Bealls[7]) opened at midnight for the first time.[8] In 2012, Walmart led several other retailers in announcing it would open its stores at 8:00 p.m. on Thanksgiving Day,[9] prompting calls for a walkout among some workers.[10]

All I know is that by 7 am, the crowds were gone.  Most of the Mall had a lot of people, but not enough to inhibit shopping.
