Assuming your instructor uses the Roll Call Attendance tool in Canvas AND it is listed as an Assignment that you can see on either the Assignments page or the Grades page, you can view the specific days you were marked absent or tardy in one of two ways in Canvas.
Viewing Your Attendance Scores in Grades
Click directly on the Grades menu item. Assuming Roll Call Attendance is listed, you can click directly on that link:
The first time (only) that you click that link, you will be asked to authorize the Roll Call Attendance tool. Simply click the Authorize button. You will then see a chart showing the number of days you were marked present, absent, or tardy. Under the chart, you will see the specific days marked present or absent and your score for those specific dates. In the example shown below, the student was absent on Thursday, February 1, absent on Thursday, February 22, and marked as late on Thursday, March 1. The instructor scores tardy days as worth 75%. (This is a setting that the instructor may choose on their own in Roll Call. Not all instructors keep track of tardiness, and the percentage to take off--if any--is set by the instructor.) Days you were present are, of course, marked as 100% for that day and are not specifically shown.
