Missing latest date using List.Min and List.Max

[Anonymous]

I've generated a calendar table based on dates that exist in another table (so, "Give me all of the dates that appear in this other table").

Here's the m defining the start and end dates in my calendar table:

let StartDate = List.Min(Table[as_of_date]), EndDate = List.Max(Table[as_of_date]),
DayCount = Duration.Days(Duration.From(EndDate - StartDate)),
Source = List.Dates(StartDate,DayCount,#duration(1,0,0,0)),
TableFromList = Table.FromList(Source, Splitter.SplitByNothing()), ...

However, when I stack my source table and calendar table side-by-side, the latest date is always missing from my calendar table:

Please help! What am I doing wrong?

Add + 1 to your duration, 

= Duration.Days(Duration.From(EndDate - StartDate ))+ 1

I just encountered the same problem again, and this solution worked again.

@Fowmy , what is it about the Duration.Days function that requires +1? Why won't this work without +1?

By adding +1, you ensure that all days between the dates are included.
If StartDate = 1/1/2020 and EndDate = 1/5/2020 then you need the results inclusive of both dates which is 5.

@Fowmy  Got it. So in M, the function Start Date - End Date is not inclusive, and +1 makes it so. Thanks!
