This question came up recently in one of my entrepreneur groups and it’s a useful tactic so I’m publishing my answer here in case it’s useful to our clients.
If you want Calendly to only offer specific time slots on specific days, here’s how to do it.
Start by choosing a date range of 1 day.
Then set a short time period of availability.
Then you end up with something like this, where you have only one day / timeslot available.
You can also set specific availability on multiple, specific days to allow one or several time slots per day.
