Sree Narayana Guru Memorial Day is observed in Kerala, India, every September 20 to honor the legacy of Sree Narayana Guru, a prominent social reformer and spiritual leader who fought against the caste system. Born as Nanu Asan in 1855, he experienced discrimination from an early age and dedicated his life to promoting social and spiritual equality. The day commemorates his contributions, including the establishment of temples that welcomed individuals regardless of caste or religion, and the opening of schools for children from lower castes to provide free education. Celebrations typically involve tributes, processions, and community prayers, reflecting the impact of Guru's teachings. Additionally, this day is recognized as a public holiday in Kerala, resulting in non-working days for schools, government institutions, and banks.
