Before you start...
If your event type duration is longer than the intervals you have set within your schedule, the schedule will not apply to that event type. For example, if your schedule says that you are free from 4:30-5 but the duration of the event type you want to apply your schedule to is 1hr long, the schedule will not apply.
From any Calendly page, select Availability.
If you have multiple schedules, select the drop down menu and then the schedule you'd like to apply.
Select the box next to Applied to, then select the event types you want to apply this schedule to.
