The simplest way to get yesterday’s date in PowerShell is by using the Get-Date cmdlet with AddDays() method. For example, in the above code, (Get-Date) retrieves the current date and time on the local computer using the Get-Date cmdlet,.AddDays(-1) subtracts one day from the current date using the AddDays method of the DateTime object, and -1 specifies the number of days to subtract, which in this case is one day.
The.ToString('yyyy-MM-dd') formats the resulting DateTime object as a string with the format yyyy-MM-dd. This specifies the year, month, and day in four-digit format, separated by hyphens. The output of this code is displayed using the format yyyy-MM-dd.
