When you need you script work in all computers around the world, please define a cultureinfo ("en-US" cultureinfo for example)
(below an example in my 'french' computer)
$date = Get-Date
$culture = New-Object System.Globalization.cultureinfo("en-US")
$date
samedi 4 mai 2013 09:55:18
$date.Tostring("dddd",$culture)
Saturday
$date.Tostring("D",$culture)
Saturday, May 04, 2013
$culture = New-Object System.Globalization.cultureinfo("fr-FR")
$date
samedi 4 mai 2013 09:55:18
$date.Tostring("dddd",$culture)
samedi
