You can do it this way:

SET @curdate = CURDATE();
SET @sql = CONCAT('SELECT hora,
       CASE WHEN data = CURDATE() 
          THEN tarefa 
          ELSE NULL 
       END AS "', @curdate, '"
  FROM tabela
 WHERE data BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 2 DAY)
 GROUP BY hora, data 
 ORDER BY hora');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

So you put the current date first on a variable and then run the query.
