Sandwiched around the deals-focused holidays of Black Friday and t-model and gf sex videosCyber Monday, Thanksgiving and Giving Tuesday — the now billion-dollar global giveback movement — represent two of the holiday season's strongest calls for solidarity.

While families and friends gather together to give thanks and honor their personal relationships, Giving Tuesday offers individuals the chance to engage in their communities at large, encouraging folks around the world to donate time, money, or support to social causes, both online and off.

The widely noted "generosity movement," which falls on Nov. 28 this year, was founded in 2012 based on the organization's concept of "radical generosity."

"While many call on philanthropists, policymakers, and grantmakers to repair broken systems, GivingTuesday recognizes that we each can drive an enormous amount of positive change by rooting our everyday actions, decisions, and behavior in radical generosity — the concept that the suffering of others should be as intolerable to us as our own suffering. Radical generosity invites people in to give what they can to create systemic change," the organization explains.

Since its more modest inception, the organization has raised millions of dollars each year through collaborations with businesses, nonprofits, and community organizations, and provided individuals with other ways to give back. A survey of last year's donors found that 84 percent of people worldwide "donated time, money, items, or voice" to their communities, with younger generations donating more money, and participating in the cause in more varied ways, than older generations.

But, while individuals are still eager to support the generosity movement, 2022 also saw a significant drop in large donor participation and a decline in nonprofit giving. More informal modes of charity, like the rise in individual crowdfunding, mutual aid, and social media-based fundraising, don't appear to be slowing down.
