I need a task to be performed once a month.

BUT

I cannot use the trigger “start the task every 1st of month at 8:00” (for example) because maybe the computer won’t be turned on at 8:00 for each month. Maybe the first, it won’t be turn on at all.

So I guess solution is to use the trigger “start when session is open” AND figure out how to limit to only a single one execution for a month lap.

I take any idea.

Thank you
