You can set up fixed time slot or interleaved time slots.

Fixed time slot

Go to “General Settings” > select “Fixed time block”

When you choose this option, combining with the “Duration” and “Working hours” you set up for the product, time slots will be established.

For example, the following product has
– Duration = 45 minutes
– Working hours: from 8 AM to 4 PM
=> Time slots will be fixed: 8:00 AM – 8:45 AM; 8:45 AM – 9:30 AM; 9:30 AM – 10:15 and so on

Flexible time slot

Go to “General Settings” => “Time slot” => select “Flexible time block” and “Time stepping”

For example, the following product has
– Duration = 45 minutes
– Working hours: from 8 AM to 4 PM
– Time stepping = 15 minutes

=> Flexible time blocks will be interleaved: 8:00 AM – 8:45 AM; 8:15 AM – 9:00 AM; 8:30 AM – 9:15 AM; and so on.
