The documentation Course relative dates is brief because the feature has not yet been implemented in many areas. I have added a little more detail to hopefully make things clearer. It is not yet implemented for quizzes.
thank you for the link to the docs.
Is the feature still in development or has it been abandoned? Relative Dates would be really usefull. Thumbs up from me.
I am a teacher in higher education and would like to set due dates relative to the startdate of my course. As this will repeat every year, relative dates would make updating the course for me (and navigation for students) much easier.
