Hi lennox25 ,
I have created a simple sample, please refer to it to see if it helps you.
Replace a blank date with today's date.
Click Trandform data>>Trandform>>Replace values.
Then change the column.
= Table.ReplaceValue(#"Changed Type",null,DateTime.LocalNow() ,Replacer.ReplaceValue,{"end date"})Then the null value will be filled with present time.
Then create a measure by using Greg_Deckler 's Net Work Days .
NetWorkDays = VAR Calendar1 = CALENDAR(MAX(Sheet3[start date]),max(Sheet3[end date])) VAR Calendar2 = ADDCOLUMNS(Calendar1,"WeekDay",WEEKDAY([Date],2)) RETURN COUNTX(FILTER(Calendar2,[WeekDay]<6),[Date])If I have misunderstood your meaning, please provide some sample data and desired output.

amitchandak Thank you - via a search I already tried this but as the end date is blank in a few rows it shows an error. Any idea how to factor this in? TIA

Greg_Deckler Thanks, great, but what about factoring in the blank end dates?

lennox25 VAR __EndDate = IF(ISBLANK(...), TODAY(), ...).
Basically just substitute today's date if it is blank.

Depending on your database, if you wish, you can add a column with the difference between dates directly in Power Query.

HI amitchandak I already have differnce between the dates as formua shown in my original question. The formula you provided works perfectly providing there are no blank dates. There are blank dates (end dates) so now the formula shows as error. I have a standard (company) date table and have brought in an excel spreadsheet that gets updated daily -which contains all the start and end dates.
