Giving Tuesday, often stylized as #GivingTuesday for purposes of hashtag activism, refers to the Tuesday after U.S. Thanksgiving in the United States. It is a movement to create a national day of giving at the beginning of the Christmas and holiday season. Giving Tuesday was started in 2012 by the 92nd Street Y and the United Nations Foundation as a response to commercialization and consumerism in the post-Thanksgiving season.
