Creating Event in MYSQL to delete records per day

I'm trying to create an automatic event in MySQL so that every 24 hours it runs the following command to delete promotions without the administrator interaction, where if the end date is less than the current date it will delete, I'm not sure if it works.

CREATE EVENT excluirPromocao
ON SCHEDULE EVERY 24 HOUR
ON COMPLETION PRESERVE
DO 
DELETE FROM promocao where data_termino < NOW();

// New event

CREATE EVENT 
    EXCLUIR_PROMOCAO
ON SCHEDULE EVERY 
    24 HOUR
ON COMPLETION PRESERVE
DO 
DELETE FROM 
    promocao 
WHERE 
    data_termino < CURDATE();
