National Foster Care Day is observed in the United States every first Tuesday of May as part of National Foster Care Month. Established in 2017, it recognizes the efforts of foster parents and highlights issues within the foster care system. The foster care system, which originated in the mid-19th century through the work of philanthropist Charles Loring Brace, aims to provide temporary care for minors who have experienced neglect, abuse, or loss. Currently, over 400,000 children are in the U.S. foster care system, many of whom face challenges as they transition into adulthood after aging out of the system. Organizations such as Project Blue and Ticket to Dream collaborate to promote this observance, encouraging individuals to wear blue, volunteer, or support foster care initiatives. The day serves as a reminder of the importance of providing resources and support to both foster children and their caregivers.
