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.
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.
