You can create appointment groups in the Canvas Scheduler. These appointment groups create a block of time in which students can sign up via Canvas for appointments to meet with you.
This article covers the following topics:
Step-by-step instructions on creating an appointment group for scheduling are in the Canvas Community Guide.
Please note: When creating time slots for your appointments, you must click the "Go" button to divide time slots into individual appointment slots. For example, you may want to schedule all office hours or advising appointments from 1-3 p.m. on Monday and Wednesday.
If you want the student appointments to be 30 minutes each, you need to set the time slots, set the number of minutes for each appointment, and click "Go."

Once you've clicked Go, you'll see the individual time slots, 30 minutes apiece, appear in the Time Range column. These are the slots students will sign up for.

When you're done setting up the appointment group, click "Save and Publish" to make the appointments available to students.
Students can find complete instructions on signing up for an appointment in the Canvas Community Guide, "How do I sign up for a Scheduler appointment in the Scheduler page?".
Note: If you're using the Calendar Feed to import your Canvas Calendar into your Google Calendar, there can be a delay of anywhere between 8-24 hours before appointment signups appear in Google Calendar.
