Summary: Figure out how many days are in a month by using Windows PowerShell.

 How can I use Windows PowerShell to find how many days are in a particular month?

 Use the DaysInMonth static method from the System.DateTime object.
            It expects the year and then the month as arguments. Here are a couple examples:

Days in October 2014:

[datetime]::DaysInMonth(14,10)

Days in February 2015:

[datetime]::DaysInMonth(2015,2)
