The wheel, the combustion engine, insulin, and the microscope are just a few things the world as we know it couldn't exist without. In real life, there are no widely known holidays celebrating such things, but we do acknowledge them and celebrate them; for example, the new Canadian $100 dollar bills have a picture of a bottle of insulin on the back, celebrating it's invention. The idea of a holiday celebrating an important invention, while not implemented in this reality, is a plausible concept And so, your mission this round is to construct a holiday which celebrates an invention integral to your culture! The invention could be a tool, a medicine, a food, a method or an organizational movement (eg: the invention of workers unions). Your invention does not have to affect the world as a whole, just enough people to merit a holiday; for example, the invention of the fur coat could be celebrated by a town that gets most of it's revenue from selling pelts, or the invention of deep-sea exploration equipment could mark the first contact of humans and mer-people.
