I had an almost identical question as posted here. I’m glad someone had the answer.

I was trying to get the tomorrow date in this exact format mm/dd/yyyy; however, Powershell kept returning mm-dd-yyyy; and if I used the Unix format of -UFormat %m/%d/%Y, then the result was a string and I couldn’t use .AddDays(1) on the Get-Date cmdlet.

Here was the solution:

Get-Date -Date $(Get-Date).AddDays(1) -UFormat "%m/%d/%Y"

This is running the Get-Date cmdlet to return a date (-Date)… Which date? Today’s date +1 ($(Get-Date).AddDays(1)), then format it the way I want: (-UFormat "%m/%d/%Y")
