This help article shows you how you can create a new time slot type.
First, open your Calendar account if it's not yet open on your screen.
At the top of your screen, you'll see words that say, "Create New," with a blue "+" sign. Click on that and choose "New Time Slot."
This will take you to a new screen that looks like what is shown below:
Click on "Create a Time Slot" and start entering information related to that time slot that describes the event, how much time is allotted for it, and anything else that describes the event during that time slot.
For example, you can select the available time or create your own. You can also choose multiple times.
Then, choose where the meetings will happen.
After that, you will select what your availability is for this availability type.
In this section, you can also opt to change the time zone that is being used.
After you have gone through all those options, click the blue box at the bottom of the screen that says, "Create Event."
Now, you've used the time slot feature to create an event.
