What is the difference between SCHEDULED, DEADLINE, and plain timestamps?
• SCHEDULED items (set with C-c C-s) will appear on your agenda on the day they are scheduled and on every day thereafter until they are done. Schedule a task if you want to be reminded to do something beginning on a certain day and until it is done. ** TODO Scheduled item SCHEDULED: <2009-03-01 Sun> • Items with a DEADLINE timestamp (set with C-c C-d) appear on your agenda in advance of the when they are due and remain on your agenda until they are done. Add a DEADLINE to an item if you want to make sure to complete it by a certain date. (The variable org-deadline-warning-days determines how far in advance items with deadlines will show up in the agenda. See this FAQ for more information.) ** TODO Item with a deadline DEADLINE: <2009-01-20 Tue> • An active timestamp (set with C-c .) will appear on your agenda only on the day it is scheduled. Use a timestamp for appointments or any reminders you want to show up only on a particular day. ** TODO Item with an active timestamp <2009-04-18
