On October 20th 2010. You expected to wear purple this day to support gay rights and anti-homophobia. It is supposed to honor the six homosexual men who have killed themselves do to homophobic behavior from their peers. I am pretty sure it was created on Facebook, but I'm not positive.
"Hey, are you wearing purple on Wear Purple Day? It's on the 20th."
On January 15th people cover their faces with purple freckles using a purple marker. It's a day to think about the mistakes of others and to deal with stress.
