Black Friday as a term has been used in multiple contexts, going back to the nineteenth century, where it was associated with a financial crisis in 1869. The earliest uses of "Black Friday" to mean the day close to Thanksgiving come from or reference Philadelphia and refer to the heavy traffic on that day. The earliest known reference to "Black Friday" (in this sense), found by Bonnie Taylor-Blake of the American Dialect Society, refers to Black Friday 1965 and makes the Philadelphia origin explicit:
JANUARY 1966 — "Black Friday" is the name which the Philadelphia Police Department has given to the Friday following Thanksgiving Day. It is not a term of endearment to them. "Black Friday" officially opens the Christmas shopping season in center city, and it usually brings massive traffic jams and over-crowded sidewalks as the downtown stores are mobbed from opening to closing.[11]
The term Black Friday began to get wider exposure around 1975, as shown by two newspaper articles from November 29, 1975, both datelined Philadelphia. The first reference is in an article entitled "Army vs. Navy: A Dimming Splendor," in The New York Times:
Philadelphia police and bus drivers call it "Black Friday" – that day each year between Thanksgiving Day and the Army–Navy Game. It is the busiest shopping and traffic day of the year in the Bicentennial City as the Christmas list is checked off and the Eastern college football season nears conclusion.

- Must burn more than you take in. The amount of calories you need depend on both your body characteristics and the things you do during the day. If you live on freezing weather you will need lots of calories just to keep warm, or if you are a high-performance athlete you need fuel to perform. So eat light and exercise a little unless you have specific reasons to do otherwise. You exercise routine does not need to be heavy but it must be steady and regular. Include stretching, start always with a warm up and end with a cool down appropriate to the intensity of what you do. With a little imagination you normal daily routine might be enough.
- Have breakfast. A good breakfast is essential; you can perform better and be less hungry during the day. Lunch and supper should be light meals. To start the day with a good breakfast will put discipline and order in your life and a natural consequence will be an appropriate weight.
- Eat balanced meals. The food you eat should provide all necessary nutrients without excess calories. Combine colors and textures and have generous portions of fruits and vegetables.
- Drink lots of water. Drink water and unsweetened tea. Use tea as a snack. Don’t drink soft drinks or other sugar-loaded beverages.
- Don’t buy junk. Do not buy junk food at all. If you have in the house, you will eat it.
- Measure. Keep track of your weight and what you eat but do not overemphasize calorie counting. If you try always to eat a balanced meal and go light on the fats you should be alright. The key is not to overeat.
- Have a hobby. Do not use food as time filler, do something with your life. Having a positive self image will help you control your weight and the overall quality of your life will improve. If you make food an issue it would be harder to control it. It’s best to put your energies and focus on something positive instead of try to offset negatives.
