Yes, when you create an event you can apply an earlier configured availability time frame. This will allow customers to only book calls within specific time frames, such as Monday to Friday, 9 AM to 5 PM for example. You can change this setting here.
When you configure the availability, you can also define the time zone.
Plus, you can synchronize SnapCall to a calendar, so that all bank holidays already configured on it will also reflect on the SnapCall Public Page.
