Where the World Gathers to Celebrate Every Day




Constitution Day and Citizenship Day on September 17th commemorates the adoption of the Constitution of the United States and those who have become United States citizens. On this day, members of the U.S. Constitutional Convention signed the Constitution in 1787.

Constitutional Convention 

While many contributed to crafting the document known today as the U.S. Constitution, James Madison wrote the draft forming the basis for the Constitution. Those who participated in its development gathered in Independence Hall in Philadelphia that sultry summer of 1787. George Washington presided over the Convention. But many “Founding Fathers” attended to other diplomatic duties, unable to participate. Thomas Jefferson, the author of the Declaration of Independence, served overseas on behalf of his country. John Adams also served abroad. However, Patrick Henry refused to attend due to principle and preferring the Articles of Confederation. Others eventually swayed Henry when convention leaders added a Bill of Rights.

When is Bill of Rights Day?

The convention lasted from May 25 to September 17, 1787. During that time, the 55 delegates debated the duties of the government, checks, and balances, and the rights and freedoms of the people. They divided the government into three branches: the legislative branch to make the laws; the executive to execute the laws, and the judicial to interpret the laws.

The delegates suffered through rough weather, heat, and illness. Despite the conditions, the formed a Bill of Rights enumerating the rights and freedoms of the people.

Benjamin Franklin, Alexander Hamilton, James Madison and George Washington all signed the Constitution.

On December 7, 1787, Delaware became the first state to ratify the Constitution. So the process began, obtaining each state’s approval. Rhode Island didn’t send any delegates to the Constitutional Convention. Their headstrong character did not appreciate a powerful government and held tight to their independence as long as they could. As a result, they were the last state to ratify the Constitution on May 29, 1790.


The 14th Amendment of the U.S. Constitution defines citizenship as “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.” On July 28, 1868, Secretary of State William Seward proclaimed the amendment ratified.

While the 14th Amendment was the first step in a long line of amendments defining citizens and their rights, it took decades to enforce some of those rights.

For example, one of a citizen’s most valued powers is the power to vote. The 15th and 19th Amendments define those rights for blacks and women. However, it wasn’t until 1924 that all Native Americans were granted citizenship. Through the Indian Citizenship Act, many Native Americans were allowed to vote for the first time. Still, this legislation did not stop some states from preventing some from voting.

This holiday dates all the way back to 1911 when schools in Iowa first recognized Constitution Day.  Then in 1917, the society known as the Sons of the American Revolution formed a committee to promote Constitution Day. Members of that committee included Calvin Coolidge, John D. Rockefeller, and General John Pershing.

In 1940, President Franklin D. Roosevelt declared “I am an American Day,” and Congress designated the third Sunday in May to celebrate it.  By 1949, the governors of all 48 states had issued Constitution Day proclamations.  On February 29, 1952, Congress changed the name from “I am an American Day” to “Citizenship Day” and moved its observation to September 17.  In 2004, the day was renamed Constitution Day and Citizenship Day.




National Apple Dumpling Day on September 17th honors a sweet delight of Autumn.
With fall fast approaching, this food holiday comes at the height of apple harvests. Peeled and cored apples are typically placed on a pastry. Then, cinnamon and sugar are sprinkled over the top. The dough is folded around the apple creating a dumpling and baked until tender. The flavor is similar to an apple pie. 

Apple dumplings are believed to be native to the northeastern United States, around Pennsylvania.  Often found among the delicious Amish recipes, it is frequently eaten as a breakfast item. However, they are also regularly eaten as a dessert and sometimes served with ice cream.

Not only do these pastry taste and smell like fall, but they look like it, too. First, the bright apples in their many colors come into our kitchens by the baskets and boxes full. Then we season them with warm-colored spices. Finally, when the pastry comes out of the oven filling our home with that delicious fragrance, it presents us with a gorgeous golden crust.

National Pawpaw Day on the third Thursday in September provides a taste of the great (forgotten) American fruit. Take a bite out of a creamy mango-banana flavored pawpaw to celebrate!

Despite their tropical taste and appearance, many pawpaws grow natively in the United States. With over 60 varieties of pawpaw to choose from, the fruit’s character changes slightly in each one.

With a blend of banana and mango and sometimes pineapple, we shouldn’t be surprised by the names given to the pawpaw. For example, the Kentucky Banana and Hillbilly Mango hint at the exciting tropical experience awaiting us. Interestingly, the pawpaw is the largest edible fruit native to the United States.

Pawpaw in History

Pawpaws are a rich part of the fabric of American history and have been from the very beginning. For example, the pawpaw Native American diets included the pawpaw as an integral part of their diets. Some may have cultivated the pawpaw, too. However, early Europeans confused the pawpaw with the papaya.

As part of United States history, rumor suggests the pawpaw was George Washington’s favorite dessert. Presidential farmer, Thomas Jefferson, cultivated the tree at Monticello. Additionally, while Jefferson served as minister to France in 1786, he shipped pawpaw seeds to friends living there. During the Corps of Discovery, Lewis and Clark wrote in their journals that they were quite fond of the pawpaw. At one point during their expedition in 1806, they relied on pawpaws when other provisions ran low.

While many people have never tasted the sweet, custard-like fruit, the day sets out to change that. This seasonal fruit enjoys a peak harvest time from late August through the first frost. Given that markets and festivals across the country offer samples, there’s ample opportunity to taste your first pawpaw.

HOW TO OBSERVE #NationalPawpawDay

Visit an orchard near you to pick a delicious pawpaw or sample them at a local farmer’s market. While you’re at it, discover recipes for desserts, too! Invite friends to discover this truly American fruit. Consider learning more about cultivating pawpaws and planting a couple. Maybe you’ll have your own pawpaw fruit in a few years to enjoy. Use #NationalPawpawDay to share on social media.

Through their one-of-a-kind pawpaw research program, the KSU Land Grant Program strives to improve growing methods, breed new improved cultivars, develop new pawpaw products, and gain a better understanding of the fruit.








On September 17th, National Monte Cristo Day recognizes the indulgent and delicious sandwich.  

A Monte Cristo is a fried ham and cheese sandwich. The French sandwich called the croque-monsieur inspired the Monte Cristo. However, the sandwich goes by other names, too. If you find a menu with French Sandwich, Toasted Ham Sandwich, or a French Toasted Cheese Sandwich, order them for a taste of Monte Cristo.

When is National Sandwich Day?

While the Monte Cristo typically offers a savory sandwich, sometimes powdered sugar and jam preserves sweeten it, too. To achieve the crispy outer coating, chefs dip the prepared sandwich in an egg batter. Then they either pan-fry or deep-fry the sandwich to perfection.

Occasionally, variations include sliced turkey and different types of cheese. Other options for serving are available, too. For example, some like to serve a grilled version. Another version may be served open-faced and heated under a grill or broiler. 

HOW TO OBSERVE #MonteCristoDay

Invite a friend or family member to join you for a Monte Cristo. Savor the delicious sandwich as an indulgent celebration and share a photo of your meal, too! Don’t forget to include your favorite versions. Do you prefer turkey over ham? Which cheese do you use? Be sure to share using #MonteCristoDay or #Bennigans on social media.
