i also thought it's funny to ask "which calendar?" when you mentioned that the calendar is hard to see, lol. but i honestly thought i can't find it since i was expecting a calendar like calendar.google.com.
maybe you can show a calendar with all courses inside so it's easier to have an overview when which course will take place (and check if you have time); for example on the courses page?
or you could also show the date here:
Btw, I am always confused by date formats since US and EU use different formats. And I never know if the site checks my IP address to give me my date format or if it doesn't.
So I have to deduce from 3/5/2024 - 4/2/2024 that you probably mean MM/DD/YYYY
