International / Global Pay It Forward Day
Founded in Australia in 2007 by Blake Beattie and inspired by Catherine Ryan Hyde’s novel and subsequent film, Pay It Forward Day challenges people to perform acts of kindness for strangers — not to repay a past kindness, but to pass one forward to someone else entirely, creating a chain of generosity.
