“Lal Kach” is a centuries-old folk ritual observed on the final day of Chaitra, marking the end of the Bengali year. Dedicated to Lord Shiva and Goddess Parvati, the festival symbolizes the victory of good over evil. Devotees especially young participants paint their bodies red, carry swords, and join vibrant processions, embodying the mythical soldiers of Shiva sent to cleanse the world of darkness. Celebrated with deep devotion in Munshiganj, Lal Kach remains a powerful expression of faith, tradition, and cultural identity.
