YMA Day is observed on June 15 to commemorate the establishment of the Young Mizo Association (YMA) in Mizoram, India. This federal holiday is dedicated to community service, where members engage in activities such as building homes, conducting cleanliness drives, and planting trees. The YMA was founded in 1935 with the aim of uniting the Mizo people, promoting societal development, and upholding Christian ethics. Participants can observe the day by learning about the Mizo culture, supporting local initiatives, or volunteering for community projects. The organization emphasizes values such as self-discipline, social commitment, and cultural preservation, symbolized by its emblem featuring a torch and ten sparks representing its commandments.
