I wouldn’t say I’m addicted to coffee. I would simply say that I need very much of it every day or I’m completely nonfunctional. In that respect, coffee is just like air or water, but with more caffeine. So, for me, every day is coffee day, but today—at least in most countries—is National Coffee Day. (A handful of countries celebrate it on other dates.) There is also International Coffee Day, coming up on October 1, and though I will certainly drink coffee then too, I think we’ll highlight another celebration on that day.
