National 529 Day is observed in the United States every year on May 29 to encourage parents to save for their children's future higher education by contributing to a 529 plan. Established in 2021 by the College Savings Foundation, this day highlights the importance of saving for post-secondary education, which can be financially burdensome without planning. A 529 plan is a state-sponsored, tax-advantaged savings vehicle that allows families to save for qualified education expenses, including tuition, fees, and room and board. The day serves as an opportunity for individuals to learn more about the benefits of 529 plans or share their experiences if they have already utilized one. The College Savings Foundation aims to assist families in achieving their educational savings goals through this observance.
