BROOKLYN - The Tuesday after Thanksgiving is known to many nonprofit organizations as "Giving Tuesday."

The movement started in 2012 by the 92nd Street Y in Manhattan, and aims to create a national day of giving at the start of the holiday season.

This primarily online push has spread like wildfire and is being used with the hashtag by many charities worldwide to get the word out about their organizations.

In Brooklyn, the Salvation Army is hoping "Giving Tuesday" will prompt charitable people to donate to its red box campaign, which provides nonperishable food and holiday decorations to local families in need, all for the cost of a donation of $65.

A spokesperson for the 92nd Street Y encourages all nonprofits and charities to use this "Giving Tuesday" campaign and make this day their own.
