Powershell days different output result is not a day number
When I use $Date1 - $Date2 output result is not a time number $Date1
$Date2
$Date1 - $Date2 the result is shown as below how can i get days in a number?
Yes, that's correct. Any [datetime] arithmetic results in what you're seeing, which is a [timespan] object (TimeSpan Struct (System) | Microsoft Docs).
The simplest way to get the difference in days is:
($Date1 - $Date2).Days
If the value of Days is negative, that just means that $Date2 is greater than $Date1.

Thank for you reply
You can see the image i used $date1 is 2022/08/05 $date2 is 2022/05/10.
So result shoud not a negative number.
And I think result is not a timestamp.because I use this
[DateTime]::FromFileTimeUTC($Date1 - $Date2).dayscant't be result to a date.
I got the same result using New-TimeSpan,
(New-TimeSpan -Start $Date2 -End $Date1).Daysbut what MS says about New-TimeSpan -days shoud be a number (Int32).
I want get the result be a "days"(number) not a timestamp .
have you get a good idea?
So, your first command is not going to work as it's mixing data types.
The call to FromFileTimeUTC is expecting an Int64, not a Timespan - which is what you get from "$Date1 - $Date2".
The simplest way to get the days is as shown below.
Similarly, New-TimeSpan returns the same result.
