Organizers call it a 24-hour dash to donate for those who need it most.
The fifth annual ROC the Day online fundraising event is underway.
It's a chance for people to donate to 550 local not-for-profit organizations.
Organizations like St. Joseph's Neighborhood Center, which provides health care for the uninsured or underinsured, depend on the generosity of others.
Director of Development and Communications, Anne McKenna, says it's a very grass-roots organization relying completely on grants and donations, and has a $1 million dollar budget.
