PowerTip: Customize How PowerShell Displays a Date

Summary: Easily customize the way Windows PowerShell displays a date.

Hey, Scripting Guy! Question How can I use Windows PowerShell to easily display the date as day-dash-month-dash-four-digit year?

Hey, Scripting Guy! Answer Use the Get-Date cmdlet,specify a custom format by using the Format parameter, and use dd for the date, M for the month and yyyy for a four-digit year (this is case sensitive):

Get-Date -Format "dd-M-yyyy"

    I find this more flexible:

    PS C:scripts> $dt=[datetime]'02/03/2001'

    PS C:scripts> $dt

    Saturday, February 03, 2001 12:00:00 AM

    PS C:scripts> $dt.ToString('yyy-mm-dd')


    PS C:scripts> $dt.ToString('yyy-M-dd')


    PS C:scripts> $dt.ToString('yyy-M-d')

    @Ed – yes – it is much a matter of what we are used to and preferences.  It is good to know about all methods as both have their strengths and weaknesses.

    @JRV indeed. [datetime]0 a cute way to get 1/1/1.  [datetime]::now returns same as Get-Date — (for me Get-Date is easier to type)

  4. jrv says:


    I think you mean that they are overloads to System.Object which supports a generic string method that returns the class name if no overload is defined.  The overload is defined in [datetime] and is a formatter.  It is the same one used internally by Get-Date.

    Yes -Get-Date cand do that as well but when you paren the Get-Date (Get-Date you are referencing the retuned object which is … System.DateTime.  It is a method on the returned object and not on Get-Date.  CmdLets really have no methods.  They only have return types.

    So yours is much the same but still different.  All methods work and are useful.  I just like how explicit the following are:





    and many, many more.

    @Dave Wyatt This is a great point, once I call one of these methods I no longer have a System.DateTime object, but a System.String object. Still, for certain types of activities it is a great technique.

  6. mredwilson says:

    @JRV you are right, it does offer  a lot of flexibility. Keep in mind, these are overloads to ToString. I can therefore also do this: (get-date).tostring('yyy-mm-dd')

  7. Dave Wyatt says:

    One thing to keep in mind is that if you call Get-Date -Format (or -UFormat), you're no longer getting back a DateTime object from the cmdlet.  You're getting a string.  That may be important, depending on how you're using the cmdlet's return value.

  8. Dave Wyatt says:

    Keep in mind that PowerShell cmdlets freqently add additional properties to the objects they return.  These properties are not present if you create the underlying .NET object yourself.

    For Get-Date, the only such property that I can see is "DisplayHint", which you would probably never miss, but this might be more of a problem with other cmdlets and classes.

    Compare-Object ([DateTime]::Now | Get-Member) (Get-Date | Get-Member) | Format-Table -AutoSize
