Black Friday and Cyber Monday have a third act, and it’s called Giving Tuesday.

The nationwide initiative, launched by New York's 92 Street Y and the United Nations Foundation, kicked off on November 27 and encourages acts of giving just as the holiday season rolls around.

Huffington Post Impact's Giving Tuesday series features ways organizations and bloggers are getting involved and what you can do. And more than 2,000 charities, businesses, religious groups and more have come together to support projects that benefit at least one registered 501c3 nonprofit.

Will Giving Tuesday become a new holiday tradition? Check out the slideshows below to see how the movement has taken off on social media!
