Quick Script: Date Ranges

Ever need to get an array of all the days between two dates?  This script will calculate the date range and load up an array with date/time objects for every date in between the entered times:


Function Get-DateRange
{ [CmdletBinding()]
Param (
[datetime]$Start = (Get-Date),
[datetime]$End = (Get-Date)
)
ForEach ($Num in (0..((New-TimeSpan –Start $Start –End $End).Days)))
{ $Start.AddDays($Num)
}
}

To use it, simply call the function

  • Get-DateRange
  • Get-DateRange -Start 7/24/14 -End 8/1/14
  • Get-DateRange -End 7/20/14

And just to pretty it up as a Function and with comment-based help:
