September 18 Celebrations: National Tradesmen Day, Hug a Greeting Card Writer Day, World Bamboo Day & World Water Monitoring Day

September 18 is a day for appreciating the people and things that quietly hold up our world: skilled hands, thoughtful words, a very fast-growing grass, and clean water.

National Tradesmen Day

National Tradesmen Day, observed on the third Friday of September, honors the electricians, plumbers, carpenters, masons, mechanics, and other skilled workers who build and maintain the roads, homes, water systems, and power grids everyone relies on. It was created in 2011 by Irwin Tools, with the first observance held on September 16 of that year, as a way to recognize trade careers and the people who work in them.

😄 Fun fact: Harrison Ford was working as a carpenter before Star Wars made him famous, so somewhere out there is some very well-built furniture with a Hollywood backstory.

Ways to celebrate:

  • Thank the plumber, electrician, or mechanic who has helped you, in person or with a handwritten note
  • Leave a positive review for a local tradesperson or trade business you trust
  • Encourage a young person to look into an apprenticeship or a skilled trade career

Hug a Greeting Card Writer Day

Hug a Greeting Card Writer Day shows appreciation to the people who craft the messages we send to the ones we love, the birthday wishes, thank-yous, and get-wells that say what we could not quite put into words. Sending greetings is an old habit: paper greeting cards were being made in Europe by around 1400, the first Christmas card was designed in England in 1843, and commercial card production took off in the 1860s.

😄 Fun fact: Hallmark took its name from the goldsmith term for a mark of quality, which is a fitting name for a company that helps people put feelings into words.

Ways to celebrate:

  • Write a card by hand to someone you have not talked to in a while, in your own words
  • Share a favorite card verse with a friend
  • Thank a writer you know, or anyone who always finds the right words

World Bamboo Day

World Bamboo Day was established in 2009 at the 8th World Bamboo Congress in Bangkok, Thailand, and promotes bamboo as a sustainable resource for building, crafts, food, and more. Bamboo is a giant grass and the fastest-growing land plant in the world, with some species shooting up about 36 inches in a single day. It is also the giant panda's favorite meal, making up about 99 percent of its diet.

😄 Fun fact: The first successful lightbulb used a carbonized bamboo filament, so bamboo has literally helped light up the world.

Ways to celebrate:

  • Swap one everyday item for a bamboo version, like a cutting board, toothbrush, or set of utensils
  • Plant a clumping bamboo in your garden or a large pot
  • Look up the many ways bamboo is used in furniture, crafts, and cooking

World Water Monitoring Day

World Water Monitoring Day invites everyday people to test the health of their local streams, rivers, and lakes, checking things like temperature, pH, turbidity, and dissolved oxygen. First held in 2003, it originally fell on October 18 to mark the anniversary of the U.S. Clean Water Act, then moved to September 18 in 2007 so more countries could take part before their waters freeze. Since 2015 the program has been managed by EarthEcho International.

😄 Fun fact: The testing kits are designed for ordinary people, so you can be a citizen scientist without owning a single lab coat.

Ways to celebrate:

  • Pick up a water testing kit and check a nearby stream, pond, or pool
  • Join a local cleanup at a creek, lake, or beach
  • Find out where your tap water comes from

September 18 Other Celebrations

National Cheeseburger Day celebrates the simple upgrade that turned a plain hamburger into an American classic. The most popular origin story credits Lionel Sternberger, a teenager at his father's sandwich shop, The Rite Spot, in Pasadena, California, who is said to have dropped a slice of American cheese on a sizzling patty in the 1920s, though O'Dell's in Los Angeles and Kaelin's in Louisville have their own claims. A Denver drive-in owner even trademarked the word cheeseburger in 1935, proving a slice of cheese can get serious in a hurry.

Chile Independence Day, known as Fiestas Patrias, marks the day in 1810 when Chile's First National Government Junta was established, the first big step toward independence from Spain. Chileans celebrate with fondas, asados, empanadas de pino, kite flying, and the cueca, the national dance said to mimic a rooster courting a hen. A second public holiday, the Day of the Glories of the Army, follows on September 19.

Rice Krispies Treats Day celebrates the marshmallow cereal bar that Kellogg's employees Mildred Day and Malitta Jensen are usually credited with inventing around 1939. The first squares were called marshmallow squares, and they soon became a Camp Fire Girls fundraiser near Kansas City. Three ingredients, one pot, and a lot of stirring have kept them a lunchbox and bake sale favorite ever since.
