How do I get 'date-1' formatted as mm-dd-yyyy using PowerShell?
You can use the .tostring() method with datetime format specifiers to format to whatever you need:

(Get-Date).AddDays(-1).ToString('MM-dd-yyyy')11-01-2013
I think this is only partially true. Changing the format seems to switch the date to a string object which then has no methods like AddDays to manipulate it. So to make this work, you have to switch it back to a date. For example:
Get-Date (Get-Date).AddDays(-1) -format D
This is the most simple solution for me:
just the current date
$tStamp = Get-Date -format yyyy_MM_dd_HHmmsscurrent date with some months added
$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd
