The `SCHEDULED' property is in fact the correct way to indicate that you wish to hide the task from the global to-do list until a particular date. `SCHEDULED' indicates the day upon which you wish to start working on the task. If there's a particular date by which the task has to be completed, the `DEADLINE' property is appropriate. The relevant org-mode manual page is: https://orgmode.org/manual/Deadlines-and-Scheduling.html I believe. -- Rohit
