New to Power BI and need help with calculating the # of days between two date columns. I tried creating a datediff column per other solutions, but that didn't work. Any other suggestions or tweaks to the formula?
Data Info:
Column 1: Created Date
Column 2: Executed Agreement Date
Note -
Solved! Go to Solution.
You must have end_dates that are prior to their corresponding start_dates!
Even if this happens only on one row in your entire dataset - you'll get this error!
Adjust your formula like this...
Days Column = SWITCH ( TRUE (), 'Table'[start_date] < 'Table'[end_date], DATEDIFF ( 'Table'[start_date], 'Table'[end_date], DAY ), 'Table'[start_date] > 'Table'[end_date], DATEDIFF ( 'Table'[end_date], 'Table'[start_date], DAY ) * -1, 0 )
You multiply * -1 to get negative numbers where the event ended before it started!
This way you'll be able to quickly identify any issues with your data indicated by the negative numbers.
Hope this helps!

what about getting the fractional number of days between two time columns, Power BI forces to round the numbers up.
Even when I get this difference in hours it rounds up when dividing on 24 to convert the difference in days not hours!
Can you help me please?
Thank you @Sean! This worked and now I can easily idenify those records that have "executed" dates before a "created" dates. Thank you for the quick response.
