## What SmartAcademy does in the background

The backend validates the branch, optional class, time range, period type, and order, then saves the class period. It prevents deleting periods that are already used in timetable entries.

## Tips

- Create periods before generating timetables.
- Use global periods when most classes follow the same bell schedule.
- Use class-specific periods when a class follows different timings.
