Young Mizo Association Day is observed in Mizoram on June 15 every year to commemorate the founding anniversary of the Young Mizo Association (YMA), the largest non-profit organization for the Mizo people. Established in 1935, the YMA was created to unite the Mizo community and preserve their cultural heritage amidst the changes brought by British colonialism and missionary activities. The organization, which was initially named the Young Lushai Association, was renamed in 1947 to emphasize its inclusivity. Celebrations typically include charity events such as tree planting, visiting the elderly in hospitals and retirement homes, and blood donation drives. The day serves as an opportunity for the Mizo people to engage in community service and strengthen their cultural identity.
