Every semester I teach the same course and for every semester there are several TODOs that should, at least initially, have the same dates relative to the starting date (i.e. the first day of class). How can I take the previous semester's course.org and easily update all of the TODO dates?
To exemplify with a MWE, imagine these were my TODOS this semester (I actually have plenty more)
** TODO prepare and distribute syllabus (first day of class: Sept 03, 2019) SCHEDULED: <2019-09-03 Tue> ** TODO explain group project (two weeks after classes started) SCHEDULED: <2019-09-17 Tue> ** TODO Create groups (on the Wednesday, three weeks after classes started) SCHEDULED: <2019-09-25 Wed>
How can I update these dates for this semester (where the first class falls, say, on January 13, 2020?)
(I am also happy to just create some sort of template (though preferably not a 'capture template') with variables for the initial dates and use a macro to fill them in).
