I believe you can do a start date and an end date–which can be confusing if you want to know which day it is on every week. I’ve had to do this as I also do not see an option to list my classes as “every Tues” or “every Thurs”.
You can also post it on the fitness website you’ve listed on your profile.
Unless I am missing something as well, that’s how I’ve listed my classes. 🙂
