I use Org-Mode to schedule most everything, including my lectures which typically are recurring events. I have learnt that I can exclude a certain range of days or weeks where no lectures take place. For this, I use:
* TODO 12:15--13:45 Lecture: Aristotle <%%(unless (diary-block 12 20 2021 12 31 2021) (and (= 3 (calendar-day-of-week date)) (diary-block 10 18 2021 02 11 2022)))> which means that the lecture on Aristotle is scheduled for every Wednesday between October 18th, 2021 and February 11th, 2022 – except for the time between December 20th, 2021 and December 31st, 2021. What I need to do for this year is to exclude single dates such as April 26th, 2022 and June 21st, 2022. Can someone please help me how to achieve this?
