I noticed you can only set the day of the month as a positive number 1..31 in the scheduled task GUI on Windows (Windows server 2003).
Is it possible to run a task only on the last day of the month? (This isn't a fixed day number, e.g. in February it could be the 28th or 29th day of the month, and in other months it may be the 30th or 31th.)
Related question, if I set a task to run on the 31th of every month, will it actually run in months with less days? Or will it run on the 1st of the next month in such cases?
