NATIONAL DOUBLE CHEESEBURGER DAY
One of America’s favorites, National Double Cheeseburger Day recognizes a food icon savored across the United States.
Hamburger. Seasoned ground beef, grilled and placed between two slices of bread or a bun. Top with sauteed onions, peppers, pickles, sliced onions, and cheese. Add condiments such as ketchup, mustard, or mayo. Any one of these combinations would create a modern American version a hamburger.
Now, double the patties and the cheese. The celebration requires it.
While the day is about the double cheeseburger, that doesn’t mean you can’t add your favorite toppings. When it comes to adding some tanginess to a burger, a few ingredients never fail. Goat cheese brightens a burger every time. But if you’re looking for a crispness, too, add some creamy coleslaw instead. Another option in this category is the reliable tartar sauce.
If you like to bring the heat, you can look to your cheeses. Pepper jack is a mild way of adding some spice. However, if you prefer to test the limits, fresh sliced jalapenos or habaneros will also do the trick.
It is most likely that the hamburger sandwich first appeared in the 19th or early 20th centuries, but there is much controversy over its origin. Over the years, the hamburger has become a culinary icon in the United States.
And Americans love their burgers! Restaurants dedicated to making them just right have been in business for generations. Even those who refrain from red meat don’t hesitate to find a way to enjoy a juicy burger. Whether the burger is charbroiled, grilled or barely kisses the heat, there’s a flavor for you.
So when something this delicious exists, double it! Then celebrate it!
HOW TO OBSERVE #DoubleCheeseburgerDay
Enjoy a delicious double cheeseburger. Add your favorite toppings. Since it’s a celebration, be sure to invite friends to join you. Whether you cook together or go out to eat, remember to #CelebrateEveryDay and share your meal using #DoubleCheeseburgerDay to post on social media.

When is Earth Day?
GREENPEACE DAY HISTORY
Greenpeace was founded on September 15, 1971, when 17 activists set sail on the Phyllis Cormack. They hoped to stop the nuclear testing about to take place off the shores of Alaska. While the testing proceeded, the protest set in motion a movement still growing today. In honor of Greenpeace, Vancouver Mayor, Gregor Robertson proclaimed Greenpeace Day in 2011.
NATIONAL LINGUINE DAY
On September 15th, National Linguine Day fills the dinner menu at home and restaurants across the country.
From the Liguria region of Italy, linguine means “little tongues” in Italian. Made from durum semolina flour, linguine is one of the world’s oldest kinds of pasta. Fettuccine and linguine both developed around 400 years ago. While both are thin, flat noodles, linguine is narrower and more elliptical in shape. As a result, linguine produces a more delicate pasta. To avoid breakage, pair linguine with thinner, lighter sauces.
However, lighter sauces don’t limit linguine’s flavor profile. In fact, linguine recipes offer a wide variety of sauces. Whether you prefer spicy pasta or seafood, linguine offers a nice base. It compliments herb and butter sauces nicely, too. When adding fresh vegetables, linguine allows the bright colors to shine. Pesto lovers rave over linguine. Another ingredient that favors linguine is earthy mushrooms.
HOW TO OBSERVE #NationalLinguineDay
If you enjoy pasta but haven’t cooked with linguine, give it a try. Try new sauces and fresh ingredients. Share recipes or test out new ones. No matter your preference, lightly seasoned, spice, or taste of the ocean, linguine will satisfy your craving.
Invite some friends over and open a bottle of wine. Break open the pasta and get cooking!
Enjoy these delicious linguine recipes and use #NationalLinguineDay to post on social media.

NATIONAL CHEESE TOAST DAY
On September 15th, National Cheese Toast Day savors the cheesy goodness of this classic dish.
Simple but delicious, cheese and toast go well together. A little butter helps everything meld together nicely, too. The crustier the bread, the better. It makes an excellent side dish, but cheese toast also serves up a satisfying snack.
While food holidays aren’t in short order on the calendar, we can’t surpass them because of the carb count. Cheese and toast perfectly combine to dunk into soup. In the middle of dinner conversation, a chunk of cheese toast waved in the air emphatically punctuates your story, especially when finishing a monologue with a satisfying bite.
It might surprise many to know the treat was created by Del Johnson. In 1958, he opened his first Sizzler restaurant. It was an instant success. And although the recipe changed a bit over the years, the concept of Cheese Toast hasn’t.
Over 60 years later, Cheese Toast continues to be a favorite dish across the country. With the best cheeses and bread, served up as an appetizer, with soup or with the main course, cheese toast pairs well with many dishes.
HOW TO OBSERVE #CheeseToastDay
Whether snacking or craving comfort food, cheese toast fits the bill. Order up some Cheese Toast for lunch or dinner. If you don’t have a Sizzler near you, try your hand at making Cheese Toast at home. Share photos or your recipes using #CheeseToastDay on social media.
NATIONAL CHEESE TOAST DAY HISTORY
Sizzler USA founded National Cheese Toast Day in 2015 to celebrate this flavorful combination.
The Registrar at National Day Calendar declared the day to be celebrated on September 15th annually.
NATIONAL NEONATAL NURSES DAY
On September 15th each year, National Neonatal Nurses Day recognizes those who care for the most fragile patients as they take their first breaths. The celebration takes place in the middle of National Neonatal Intensive Care Awareness Month.
Neonatal nurse specialists work with newborn infants who are delicate at birth due to a variety of reasons. They may have been born premature or born with birth defects, infection, surgical issues, or heart problems. Neonatal nurses also provide care for healthy newborn infants immediately following their birth.
The demand for neonatal nurses continues to rise. Their expertise and training meet the needs of the youngest, most fragile, and critical patients in any hospital. Many require 24-hour care and attention. While most neonatal newborns spend a month or two in the hospital, some require longer care. The neonatal nurse provides their care for the duration of the stay. Some neonatal nurses provide care beyond the neonatal period.
The day celebrates their dedication and commitment to the profession. It also is a way to encourage others interested in the field to take a closer look. With the growing demand for qualified neonatal nurses, the more students stepping up to the challenge of this satisfying career, the better.
HOW TO OBSERVE #NeonatalNursesDay
Thank a neonatal nurse you know by sending them a card. Let them know how much you appreciate the work they do. Hospitals and other professionals will take the time to celebrate their neonatal nurses and encourage them every day. If you’re a neonatal nurse, plan to attend a job fair to share your experiences with others considering the profession. Use #NeonatalNursesDay to share on social media.
NATIONAL NEONATAL NURSES DAY HISTORY
The National Association of Neonatal Nurses established National Neonatal Nurses Day in 2000 to showcase the work these specialists do every day. The day honors neonatal nurses across the Nation for the care and protection they give to save the precious lives of babies.
NATIONAL FELT HAT DAY
On September 15th, tip your hat for National Felt Hat Day! The observance recognizes a stylish head protection worn throughout history.
Historically, men and women wore hats as protection and status symbols, too. This time of year, people traded in the lighter, cooler straw hat for the warmer felt hat. Additionally, etiquette dictated what hats men and women wore and where. For example, good behavior required men (mostly) to learn to don and doff the hat at an early age.
While primarily made from wool, felt can also be made from the fur of other animals. Usually, rabbit and beaver were the furs of choice. During the 16th and 17th centuries, beaver hats reached popularity but over trapping depleted the population.
The phrase “a mad as a hatter” comes from the use of mercury nitrate in haberdasheries in the late 18th and early 19th centuries. Over time, daily exposure to this metal caused these tradesmen to develop dementia, tics and other symptoms. These unusual side effects caused people to believe their hatters had gone mad.
Over the centuries, many styles of felt hats have made their debut. We can identify an era by many of them. Its buckle will quickly identify the Quaker, and the stovepipe reminds most Americans of one of its most beloved presidents. Others have odd names such as pork pie, bowler, and stingy brim.
HOW TO OBSERVE #NationalFeltHatDay
Celebrate by donning your favorite felt hat and snapping a picture. Try out styles you’ve never worn before. Go on a hat shopping expedition. Study up on millinery techniques. You might just find out the Fanchon, flower pot, Reubens, Fedora, or a Panama is really your style instead. Use #NationalFeltHatDay to post on social media.

NATIONAL CREME DE MENTHE DAY
National Crème de Menthe Day on September 15th recognizes the creamy peppermint-flavored liqueur used in cocktails and desserts. Enjoy your favorite combination to celebrate!
Many of the liqueurs we enjoy today started as tonics and cure-alls. And we thank pharmacists for bringing them into existence. Crème de menthe (mint cream) is one of those liqueurs. French pharmacist, Emile Giffard, studied the cooling and digestive properties of mint. His research led him to a recipe for crème de menthe.
Crème de menthe is sweet and mint leaves (usually Corsican mint) give crème de menthe its green color. However, when extracted, the liqueur is colorless. This form of the liqueur is called white crème de menthe. Unless color is essential, both varieties have similar flavors and are interchangeable in recipes.
The traditional formula involves steeping dried peppermint or Corsican mint leaves in grain alcohol for several weeks. This method creates a natural green color. The following steps include filtration and the addition of sugar.
Several cocktails include crème de menthe as an ingredient. Two popular cocktails include Grasshopper and Stinger. Because of mint’s digestive qualities, crème de menthe makes an excellent after-dinner drink. Also popular in the kitchen, it is used in many recipes as a flavoring. To make a chilly adult milkshake mix crème de menthe with ice cream. Add chopped pecans or shaved chocolate as a garnish.
HOW TO OBSERVE #CremeDeMentheDay
Try crème de menthe for the first time or the hundredth. Add it to a dessert or mix up a cocktail. Stir in some chocolate for a mint chocolate flair. Encourage your favorite restaurant or dessert shop to celebrate the day, too. Give them a shout-out for their amazing creations, too. If you don’t have a recipe to try at home, check these out:
