Calculate dates between 2 dates but exclude Start / End date

[TMO_KY]

I have an interesting ask, I have a code that I use to find dates between 2 given dates; 

= Table.AddColumn(#"Renamed Columns", "Work Days", each { Number.From([First Date])..Number.From([Last Date]) })

What I want to do, is extract the dates between the 2 columns (First Date, Last Date) and exclude those given dates.  For example if the Start Date is 1/1/2020 and the Last Date is 1/10/2020.  I only want to return the dates 1/2/2020-1/9/2020 in my data.  Is this possible?  Currently it expands all rows which is fine but it includes the start and last date; however these dates are never the same and can change based on project length which is why I can't use any workday formulas.  The exlusion doesn't have to be within the same formula, I can always add another step after if that's easier.  I'm just stumped on how to make it work.

Hello,

use Date.AddDays ;

Table.AddColumn(#"Renamed Columns", "Work Days", each { Number.From(Date.AddDays([First Date],1))..Number.From(Date.AddDays([Last Date],-1)) })

Best regards

@arq52  Much appreciated!  Now I have less steps in my query.  🙂

*Update*  

So I ended up creating an additional custom column that uses a filter with a true false statement then filtered out the "true's".  This works but if anyone has a better workaround with less "steps" I'd appreciate it.
