From the National Philanthropy Day® Official Website:
NPD is a celebration of philanthropy; giving, volunteering and charitable engagement that highlights the accomplishments, large and small, that philanthropy and all those involved in the philanthropic process, makes to our society and our world. National Philanthropy Day® is both an official day and a grassroots movement.
Every year, since 1986 when President Ronald Reagan first proclaimed November 15th as National Philanthropy Day®, communities across the globe have celebrated by hosting events to recognize activities of donors, volunteers, foundations, leaders, corporations, and others engaged in philanthropy. Since that first NPD, participation has grown year after year.
