Frequently Asked Questions

How does the Attendance Calculator work?

The Attendance Calculator tracks attendance for multiple subjects or events. For each subject, you set the total number of sessions and a required attendance percentage. You can then mark each session as attended or not, and the tool calculates your current attendance percentage in real-time.

How is the attendance percentage calculated?

The attendance percentage is calculated using the formula: (Sessions Attended / Total Sessions) × 100. For example, if you attended 20 out of 30 sessions, your attendance percentage is (20/30) × 100 = 66.67%. The tool automatically updates this as you mark sessions.

Can I track multiple subjects?

Yes! You can create as many subjects as you need. Each subject has its own attendance tracking, so you can monitor attendance for different classes, events, or activities separately. The Stats tab shows an overall summary across all subjects.

What do the different attendance status colors mean?

Green (Good) - Your attendance is at or above the required percentage. Yellow (Warning) - Your attendance is close to the required percentage. Red (Needs Attention) - Your attendance is below the required percentage and needs improvement.
