How do I specify what part of my input string is the date and month?
If the input is 01/10/2017, this can be read as 1st Oct 2017 and 10th Jan 2017. Both are correct.
I want to be explicit that 01 is date and 10 is month, so that irrespective of locale and time format I can get a consistent result.
Sample code:
get-date -Date '01/10/2017'
The output is:
Tuesday, January 10, 2017 12:00:00 AM
The desired output is:
Sunday, October 01, 2017 12:00:00 AM

I have a solution for you. It requires that the culture as one of the arguments.
([datetime]::ParseExact($date,"dd/MM/yyyy",[Globalization.CultureInfo]::CreateSpecificCulture('en-GB')))
A culture does not have to be specified. However, the argument for it does, otherwise you will get an error:
Cannot find an overload for "ParseExact" and the argument count: "2".
[cultureinfo]::InvariantCulture or $null can be used as the third argument:
$date = "01/10/2017"
[datetime]::ParseExact($date, "dd/MM/yyyy", [cultureinfo]::InvariantCulture)
[datetime]::ParseExact($date, "dd/MM/yyyy", $null)
Output in all three cases
01 October 2017 00:00:00

Try this:
Get-Date(Get-Date -Date $date -Format 'dd/MM/yyyy')

Read the documentation or run Get-Help Get-Date in PowerShell console.
You should read the documentation on MSDN that covers Get-Date PowerShell cmdlet and provides all the necessary examples. Take a closer look at Parameters section.
