A timestamp may be preceded by special keywords to facilitate planning:
Meaning: the task (most likely a TODO item, though not necessarily) is supposed to be finished on that date.
Insert ‘DEADLINE’ keyword along with a stamp, in the line following the headline.
On the deadline date, the task will be listed in the agenda. In
addition, the agenda for today will carry a warning about the
approaching or missed deadline, starting
org-deadline-warning-days before the due date, and continuing
until the entry is marked DONE. An example:
*** TODO write article about the Earth for the Guide The editor in charge is [[bbdb:Ford Prefect]] DEADLINE: <2004-02-29 Sun>
Meaning: you are planning to start working on that task on the given date7.
Insert ‘SCHEDULED’ keyword along with a stamp, in the line following the headline.
The headline will be listed under the given date8. In addition, a reminder that the scheduled date has passed will be present in the compilation for today, until the entry is marked DONE. I.e. the task will automatically be forwarded until completed.
*** TODO Call Trillian for a date on New Years Eve. SCHEDULED: <2004-12-25 Sat>
Some tasks need to be repeated again and again. Org mode helps to organize such tasks using a so-called repeater in a DEADLINE, SCHEDULED, or plain timestamp. In the following example
** TODO Pay the rent DEADLINE: <2005-10-01 Sat +1m>
+1m is a repeater; the intended interpretation is that the task
has a deadline on <2005-10-01> and repeats itself every (one) month starting
from that time.
This is quite different from what is normally understood by scheduling a meeting, which is done in Org-mode by just inserting a time stamp without keyword.
It will still
be listed on that date after it has been marked DONE. If you don’t like
this, set the variable
