After Black Friday, Small Business Saturday, and Cyber Monday, comes Giving Tuesday.
It's a day that organizers hope you'll give more of yourself.
"That means everything from volunteering, to donating, to raising awareness about causes," said #GivingTuesday organizer, Aaron Sherinian.
Any cause, any charity near and dear to your heart, organizers want you to act today, then share the good deed on social media to encourage others.
"Whether that's tweeting a picture of what you're doing, posting it to your Facebook page or telling people in your community, school or church group, we want people to talk about giving today," said Sherinian.
Because the average age of the American donor is 65, the social media aspect of the campaign is intended to attract younger donors.
That's also why there's a Twitter hashtag in the title and why everything can be done online.
The effort has the backing of heavy hitters in philanthropy and about 2,500 other organizations, like the U.N. Foundation where Aaron Sherinian is a vice president.
"This is about changing the conversation around the holiday shopping season so that it's about the giving season," said Sherinian.
Organizers don't expect any official figures on how the first #GivingTuesday goes; they're just hoping it becomes another holiday tradition.
