Calculate Time Difference between 2 cross days

Step 0: I use these data and calculate by 'Minutes'.

Step 1: I duplicate the 'Duration_Mins' column.

Step 2: I chande the type of 'Duration_Mins - Copy' column.

    'Duration_Mins - Copy' column: 'Time' -->  'Decimal Number'

Step 3: I rename the 'Duration_Mins - Copy' column.

    'Duration_Mins - Copy' --> 'Duration_Day'

Step 4: I add a 'Duration_Min' column and change the type of the column.

Step 5: I add a 'Day' column and rename it. ('Day' --> 'S_Day')

Step 6: I add a 'Day' column and rename it. ('Day' --> 'E_Day')

Step 7: I add the 'Flag' column.

Step 8: I unpivot 'StartTimeStamp' and 'EndTimeStamp' columns.

- After -

Step 8: I add a column and make a matrix.

Cal_Duration_min = IF([Flag]="Divide" && [Attribute]="StartTimeStamp",DATEDIFF([Value],DATE(YEAR([Value]),MONTH([Value]),[E_Day]),MINUTE),IF([Flag]="Divide" && [Attribute]="EndTimeStamp",DATEDIFF(DATE(YEAR([Value]),MONTH([Value]),[E_Day]),[Value],MINUTE),IF([Attribute]="StartTimeStamp",1440*[Duration_Mins],0)))
