The official count is 8,302 partners for #GivingTuesday tomorrow. More organizations might get involved but the official count is now frozen in time. It is more than triple the 2,500 reported last year for the inaugural event.

“We were really overwhelmed at how this call to generosity resonated so intensely,” said Beverly Greenfield, director of public relations for the 92nd Street Y (92Y) in New York City, where the idea for #GivingTuesday originated in partnership with the United Nations Foundation.

This year’s event will be bigger. “We set a goal of 5,000 partners and already beat it,” said Greenfield, a week before the event. “We’re not quite as surprised this year but the response has been extraordinary.” At least $10 million in giving was tracked to last year’s event.

A partners is loosely defined as a 501(c)(3) with a specific #GivingTuesday initiative or a for-profit business, school, religious or community group committed to spearhead a project benefiting at least one registered charity 501(c)(3) in the U.S.

Americans have Black Friday and Cyber Monday, the Friday and Monday after Thanksgiving, which are all about dropping prices to entice consumers to spend money. Black Friday is also characterized by long lines and near-riots to be the first through the doors. “The idea behind (#GivingTuesday) was it brings us back to the spirit of Thanksgiving,” said Jean Case, CEO of the Washington, D.C.-based Case Foundation. “Being able to give back in the consumption-focused window (after Thanksgiving) makes a lot of sense.”

The hashtag that precedes the name everywhere is intentional, said Greenfield. “We wanted to let people know that this is about community that can come together through social media,” she said. “It’s a symbol that this is a social media-driven movement. We left the hashtag in the name so that it’s always there wherever you see it.”

Henry Timms, interim executive director of 92Y, said one of the biggest changes operationally this year is more time. “Last year we had about 70 days between (the announcement of the) launch and Giving Tuesday,” he said. “We had more time this year, so that was important. People having time to plan and think about how Giving Tuesday fits into their comprehensive year-end campaign, that’s really important.” Timms admitted the response for the first Giving Tuesday, held on Nov. 27, 2012, was a pleasant surprise: “We never anticipated this kind of support and interest,” he said.

#GivingTuesday is not a program of 92Y or any other organization; it’s a movement, and one of its strengths is participants’ ability to make the day their own. “We knew the success of this kind of project would rely on the fact that it’s owned by everyone involved,” said Greenfield. “It was a conscious decision to create a movement that’s very open that each partner can make their own.”

After setting up a match pool of $25,000 last year, the Case Foundation decided to dial it up to $100,000 for this year, divided into donation matching for nonprofits ($90,000) and prizes for donors ($10,000 worth of merchandise). “We’ve always seen the power of matching,” said Case. “We think there’s no exception here. While giving is a selfless act, people are sometimes motivated by prizes to act with urgency.”
