Today is Fairfield County Giving Day.  Some 430 nonprofits have signed up to receive donations, with various fundraising goals throughout the day unlocking additional cash prizes.  Since its creation in 2014 by the Norwalk-based Fairfield County’s Community Foundation, Giving Day has helped about 750 organizations raise nearly $6 million dollars.  About $1.4 million was raised last year alone.  Several Greater Danbury area non-profits are among the organizations signed up to participate in the philanthropic event.
