National Thrift Shop Day was created to celebrate the secondhand economy — the resale market that has grown from consignment stores and Goodwill bins into a $200 billion global industry, driven by sustainability concerns and Gen Z’s preference for vintage over new. Indonesia Independence Day marks August 17, 1945, when Sukarno and Mohammad Hatta proclaimed Indonesia’s independence from the Netherlands — a declaration made just two days after Japan’s surrender in World War II, initiating a four-year independence war before Dutch recognition in 1949. Black Cat Appreciation Day was established to combat the superstitions that make black cats the most euthanized color in U.S. shelters — research has found no difference in personality between black and other-colored cats, but adoption rates remain lower. Gabon Independence Day marks August 17, 1960, when Gabon gained independence from France. Vintage, a 1945 proclamation, a misunderstood feline, and a Gabonese flag.
