The Registrar at National Day Calendar proclaimed National Check Your Wipers Day in September of 2021. As of 2022, due to seasonality, MICHELIN® officially requested May 16th become National Check Your Wipers Day (Día Nacional de Revisar Tus Limpiaparabrisas) for countries in Latin America. Additionally, MICHELIN® changed the November 16 observance to International Check Your Wipers Day to be celebrated in the U.S., Canada, Europe and Asia. Both the May 16 and November 16 observances are a reminder to educate drivers about checking their wiper blades.
