Hi ​@Jeffnewearth - Thanks for reaching out!

In this case, you would need to adjust the availability settings for this specific event. To be able to set the last week of the month as available, you’d first remove any weekly hours for the event, then, add date specific hours for the last week of each month:
 

Let me know if this works or if you have any questions!

And this doesn’t affect availability dates that were set for other events? 

Hi ​@Shani-Lee - Yes thats correct, as long as its done within the event settings, it would not effect any other event.

Thank you. That was my main concern. I’d like to set up an ongoing weekly complimentary session for first timers. And only have them be able to book that time. But didn’t want to mess anything up with regular schedule that I had set up. I appreciate your help. 

Also, is there a way, to go in and book for all monday’s? for this set session without affecting the availability of the same day? 

Glad to hear it!

If you’re wanting only mondays to be available through the booking page, you can select Monday on the Weekly Hours portion to allow that day to be available every single monday at the time you set. If you want to have overlapping meetings, you can follow the instructions here: 

Let me know if you have any other questions!

Thank you! I really appreciate your help. :)
