National Oreo Cookie Day - March 6


Be ready to observe by having your glass of milk handy as it is National Oreo Cookie Day.  This day is recognized across the nation each year on March 6th.

The Oreo sandwich cookie is made up of two chocolate disks containing a sweet cream filling and is loved by millions.  Since it’s introduction, the Oreo cookie has become the best-selling cookie in the United States.

The National Biscuit Company (today known as Nabisco) first developed and produced the “Oreo Biscuit” in 1912 at its Chelsea factory in New York City. Today, the block on which the factory was located is known as “Oreo Way”.

  • The name “Oreo” was first trademarked on March 14, 1912.
  • The first Oreo cookies in the United States sold for 25 cents a pound in clear glass topped novelty cans.
  • In 1912, the Oreo Biscuit was renamed to “Oreo Sandwich”.
  • In 1948, the Oreo Sandwich was renamed to “Oreo Creme Sandwich”.
  • William A. Turnier developed the modern-day Oreo design in 1952 to include the Nabisco logo.
  • Nabisco’s principal food scientist, Sam Procello, developed the modern Oreo cookie filling.

National Dentist's Day - March 6


Annually observed on March 6, National Dentist’s Day was created as a day set to say “Thank You” and show appreciation to your dentist.

In many cases, the day of our dental visit usually has us a bit nervous and sometimes anxious.  We would often rather be someplace else than sitting in a dental chair.  The dentist is not the person most of us look forward to seeing.  However, when our checkup is done, our teeth are cleaned, the cavities are filled, the broken tooth is fixed, or a toothache is gone, we appreciate what the dentist has done for us.


If you are not already in the habit of using them, this would be a great day to make a commitment to better dental habits. Use #NationalDentistsDay to post on social media.

National Frozen Food Day - March 6


Observed annually on March 6, National Frozen Food Day has been celebrated since 1984.

The frozen food aisle is as common in the grocery store today as ATMs and self-checkouts and is a convenience we don’t give a second thought to unless the power goes out.

Credit for the flash freezing of fruits, vegetables, meats and seafood to preserve flavor and quality is given to American inventor, entrepreneur and naturalist Clarence Frank Birdseye II.

Food preservation by freezing had been done long before Birdseye had ever begun experimenting with the process. Birdseye discovered the key was freezing the food quickly. Flash freezing forms small ice crystals which prevent the cell walls from bursting. Large ice crystals turn the food to mush.

Birdseye applied for a multitude of patents, but one of his earliest is from 1927 for a process to flash freeze foods. Consider that in 1930 only 8 percent of American households had refrigeration units in their homes. A frozen food patent in 1927 was a visionary step in a long chain of events to make frozen foods a marketable product.

In 1930, the Birdseye label, owned by the General Food Corporation, began selling 26 products to 18 retails stores in and around Springfield, Massachusetts. Clarence Birdseye continued his work with General Foods Corporation.

Birdseye died October 7, 1956, but the name and products he inspired continue today.

Frozen dinners, first known as TV dinners, came on the scene in 1954 and were introduced by Swanson. These pre-cooked meals only needed to be heated through in the oven to be ready to eat.  No cooking skills were required. Pre-heat the oven, cook for the required length of time and eat.

The invention of the microwave has also changed the types of frozen foods and just how convenient these items can be.  Over the years, frozen foods have developed to meet consumer demand. A variety of family sized meals, health conscience meals and even organic meals have hit the markets in recent years.


Take a trip to your local grocery store and find one of your favorites in the frozen food aisle!! Use #NationalFrozenFoodDay to post on social media.


Proclamation 5157 was signed by President Ronald Reagan in which it said:  “Now, Therefore, I, Ronald Reagan, President of the United States of America, do hereby proclaim March 6, 1984, as Frozen Food Day, and I call upon the American people to observe such day with appropriate ceremonies and activities.”
