For those not in the know about this unofficial holiday, here's a brief explanation: In Japanese, the numbers six and nine are pronounced "rokku" when placed next to each other, and since Mega Man is known as "Rockman" in Japan (or, to be precise, "Rokkuman"), the Japanese fans decided to make 6/9 the unofficial holiday for Mega Man! It eventually became a pretty popular thing, even managing to get official recognition from Capcom, so now it's a holiday that we Mega Man fans celebrate every year!
