title: Get the number of Days in the current month using powershell
body: <p>I have the need to retrieve the number of days in the current month, and despite my research, I have yet to find anything in powershell that does it.  The following is what I have currently built to get the result I want.  is there a better way to do it?</p>
  
  <p>Please note that I am limited to Powershell</p>
  
  <pre><code>    #check to see if this is a leap year
      function LYC
      {
          if ([System.DateTime]::isleapyear((Get-Date).Year))
          {
              $Global:LY = True
          }
      }
      #Get the number of days in current month
      function fNOD
      {
          $MNum = (Get-Date).Month
          switch ($MNum)
          {
              1   {$Global:DaysInMonth=31}
              2   {
                      LYC
                      if (LY)
                      {
                          $Global:DaysInMonth=29
                      } else {
                          $Global:DaysInMonth=28
                      }
                  }
              3   {$Global:DaysInMonth=31}
              4   {$Global:DaysInMonth=30}

      }
