- September 20th - National Tradesmen Day. Tradesmen build our homes, they pave our roads, they construct buildings for our businesses and schools. Although they are often overlooked, many people should realize that they are the backbone of every nation because they are doing the jobs that keep the world running and life moving. That’s why there is a day dedicated to Tradesmen and their hard work. The day often includes recognition events, celebrations, and activities that identify and honor the hard work that they do. Irwin Tools, a world-class manufacturer of a broad line of professional hand tools and power tool accessories, founded this very important day in 2011.
- September 20th - National Punch Day. The word punch means five, originating from the Hindustani word panch. National Punch Day sadly isn’t an excuse to drink five glasses of punch; rather, it celebrates the traditional punch base recipe of five key ingredients, which most punches still use – alcohol (usually spirits), lemon (or other fruits), sugar, water, and tea (or other spices, e.g. cinnamon). Punch made its way to England in the 17th century. It did this via those who worked for the British East India Company. They brought the drink to the UK. After this, it then spread across Europe, soon becoming an extremely popular drink, which was served at family gatherings and parties. Punch is served in a punch bowl, which is a large bowl. These were a common household item in Europe in the 17th and 18th centuries. A lot of the bowls were passed down as heirlooms, as they came with ornate stands and were beautiful statement pieces.
- September 20th - National Pepperoni Pizza Day. Pepperoni pizza has become the standard pizza for people all over the world. In fact, it stands apart as the singularly most ordered type of pizza on the entire planet. The pizza is believed to have first been developed in Italy in 1889 by Raffaele Esposito, though others claim that the first one was sold in 1738 in Naples, Italy. Pepperoni is one of many cased meats (like salami, but spicier) that likely traces its origins back to Italian immigrants to New York City in the early 1900s. It wasn’t until the 1950s that pizza became a widespread dish in the United States. The first mention of pizza in the US was in a New York Times article that called it “a pie popular in Southern Italy”. And, even then, it was continuing to develop flavor over time.
- September 20th - National Fried Rice Day. In 2018, National Fried Rice Day was founded by Benihana restaurants. The day is established in connection with the restaurant’s accomplishment of setting a new Guinness World Record for the longest cooking marathon.
