The HPA partnered with This Star Won't Go Out to promote and discuss Esther Day.
Esther Earl was a member of the Harry Potter and Nerdfighter communities who died from thyroid cancer at the age of 16 in August of 2010. Earlier that month, on her birthday, John and Hank Green first celebrated Esther Day - a holiday whose theme they had left up to Esther's choosing. After some consideration, Esther chose to make her holiday about love among friends and family. The holiday has been celebrated every year since.
The Esther Day campaign led a discussion on the holiday's themes and encouraged action in the holiday's spirit. It culminated in an Esther Day celebration at LeakyCon - a Harry Potter-based multifandom convention now called GeekyCon - in Orlando.
