May 29 is nationally recognized at 529 College Savings Day, a day (mostly celebrated by a niche group of higher education experts and personal finance enthusiasts) to draw attention to the tax-advantaged savings plans offered by all 50 states and the District of Columbia. 

First created in 1996, 529 plans are state-sponsored investment accounts that savers can contribute to for a beneficiary's education expenses including tuition, fees, books, housing and technology. Savers can choose any individual to be a beneficiary and when funds are withdrawn from a 529 plan for educational expenses, the money earned in the account while it was invested is not subject to federal income taxes, and in many cases state taxes as well.
