Want to double your impact? Give on Tuesdays.

During this holiday season, many people shift their focus from investing to philanthropy. The Case Foundation has teamed up with Crowdrise, Network for Good and Six Degrees to leverage this goodwill by hosting a web page where donations will be matched...on Tuesdays.

The 5 Giving Tuesdays campaign begins next week and extends through January 6, 2014.

According to the Case Foundation, the campaign "will spotlight one of five creative ways to give back and help others through exclusive content and $75,000 in grants and prizes. New prizes will be up for grabs each week and will include Amazon gift cards, Timex Fitness Watches, Shop for a Cause products from Tory Burch, EcoVessel water bottles and more. One grand prize winner will receive $1,000!"

Lots of organizations, from the United Nations to local charities, have joined the movement.

So if you are going to give anyway, why not give on a Tuesday and do more good with your money?
