I need to subtract one month from a date called ArchiveDate but I want the first business day of that month. For example if my ArchiveDate is 9/2/2018 I would like to have 8/1/2019.

This is what I have:

```DECLARE @ArchiveDate date = '9/2/2019'

CASE WHEN
DATEPART(weekday, DATEADD(MONTH, -1, @ArchiveDate)) = 1
THEN 1
WHEN DATEPART(weekday, DATEADD(MONTH, -1, @ArchiveDate)) = 7 THEN 2
ELSE 0
END
```

What I get from this is 8/2/2019 but as you can see I want 8/1/2019.

```SELECT
CASE
WHEN DATENAME(WEEKDAY, DATEADD(mm, DATEDIFF(mm, 0, @ArchiveDate) - 1, 0)) = 'Saturday'
THEN DATEADD(mm, DATEDIFF(mm, 0, @ArchiveDate) - 1, 0) + 2
WHEN DATENAME(WEEKDAY, DATEADD(mm, DATEDIFF(mm, 0, @ArchiveDate) - 1, 0)) = 'Sunday'
THEN DATEADD(mm, DATEDIFF(mm, 0, @ArchiveDate) - 1, 0) + 1
ELSE
DATEADD(mm, DATEDIFF(mm, 0, @ArchiveDate) - 1, 0)
END
```

This will return the first BUSINESS DAY of the previous month.
