There are a few complex habits/tasks that I wish orgmode to handle, and I'm not quite sure how to program them: A habit that has to be done twice a day, between certain hours (E.g. 8-9 and 18-19). A habit that has to be done over the weekend (Between Thursday-Saturday). A task that occurs every 6 months, twice a day between certain hours, for a duration of 21 days total. Can someone help with adding the right SCHEDULE?
