I first heard about World Goth Day last year (including Top 10s), and they cropped up again on Facebook this week.
World Goth Day (May 22nd) is exactly what it says on the wrapper a day where the Goth scene gets to celebrate it’s own being, and an opportunity to make its presence known to the rest of the world.
You can find them here: World Goth Day website, World Goth Day Facebook page, and Facebook event
