Since task scheduler API has been changed after Vista & Server 2008, scheduling a task with schtasks is (as much as I know) the only way that works on both Windows 2003 Server and Windows 2008 Server.

I need to create a task that will run every on 5th and 20th of each month. Is this possible with schtasks.exe?

Creating a scheduled task that will run on every sunday and monday of a week is possible with:

schtasks /create /tn test /tr "cmd.exe" /sc weekly /d mon,sun

But with the same aspect, any of the following is not working.

schtasks /create /tn test /tr "cmd.exe" /sc monthly /d 5,15

schtasks /create /tn test /tr "cmd.exe" /sc monthly /d "5 15"

Any ideas?

  • The mon,sun syntax doesn't work for me either. – jwg Sep 24 '14 at 16:30
  • Having a non-English locale settings may cause this, I believe. – dereli Sep 27 '14 at 21:32
  • Not sure, because /d "mon sun" does work. – jwg Sep 28 '14 at 22:23

Schedule two monthly tasks. One for the 5th and one for the 15th.

    Actually, I don't like this, but this seems to be the only solution. – dereli Jan 26 '10 at 18:43

You could create a task using an XML file:

schtasks /Create /XML xmlfile

(see documentation).

The XML should contain a <ScheduleByMonth> section:


You can create the XML file using the GUI version of the Task Scheduler. Use the "Export" function. Here is an example file:

<?xml version="1.0" encoding="UTF-16"?>
<Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
          <January />
          <February />
          <March />
          <April />
          <May />
          <June />
          <July />
          <August />
          <September />
          <October />
          <November />
          <December />

  • /xml argument is not supported on Windows 2003 Server. – dereli Jan 26 '10 at 18:41
