Why are my dates not in the correct order? even though I have to format I want and they are ascending with respect to the month part of the date, they are descending wrt the year! how can I fix this?

1 2 3 4 5 6 SELECT FORMAT (Start_Date, 'MM/yyyy') as Date ,COUNT (DISTINCT [Trip_ID]) as Total_PickUps sum (Duration) as "Total_Duration" from BikeTrip GROUP BY FORMAT (Start_Date, 'MM/yyyy') ORDER BY FORMAT (Start_Date, 'MM/yyyy') ASC
