Mazingira Day, also known as Environment Day, is observed in Kenya every October 10. This public holiday was established to emphasize environmental protection and conservation, marking a shift from its previous focus on cultural heritage. Originally instituted as Moi Day to commemorate the rise to power of Daniel arap Moi, the holiday has undergone several name changes, including Huduma Day and Utamaduni Day, before adopting its current name in 2024. The renaming aimed to highlight the government's efforts to accelerate forest restoration and address climate change. Celebrations typically involve tree planting and various environmental activities, reflecting the importance of ecological stewardship in Kenya.
