    Hi leroy773,


    Based on your description, you want to compare your current row with previous row, right? If that is the case, firstly, go to query editor of Power BI Desktop and add an index column in your current table.

    Secondly, add a new column and write DAX formula to compare date values of the rows.

    Duration = DATEDIFF(Table5[Column1],IF(Table5[Index]=0,Table5[Column1],LOOKUPVALUE(Table5[Column1],Table5[Index],Table5[Index]-1)),HOUR)/24


    For more details, you can review the example in the attached PBIX file. 



    Thanks,
    Lydia Zhang

I don't follow what you mean by 'calculate' .....  but Lydia gave method in post on how to join another row's value using LookupValue and (Index-1) 

 

not sure if the right solution is -1 or +1 but in any case it is the concept to use
