Thanks for the tool. Curious why you only allow hours form 9am-5pm of subsets of that only, what if someone wants to book evening hours? I was ready to start sharing my new cal.com link but this was a showstopper.
I didn't change the default availability configuration during signup. However, after logging in and navigating to the Availability page, I'm able to create multiple schedules and time ranges per day as late as 11:59pm.
I figured it out, basically, the start-time is constrained by the end-time, which is why I couldnt change the start-time until I changed the end-time first. It wasnt obvious at first, but makes sense. That said, i do wonder if a better UI control would make the operation more obvious.
