Bell Schedule Maker

The tool chains your periods together starting from the first bell. Each period has a length in minutes, and an optional passing period is added after it before the next class begins, so start and end times are calculated automatically.

1. Set the details: name the schedule, choose when the first bell rings, and pick a default passing-period length.
2. Add rotation days such as A Day and B Day; each day keeps its own period names but shares the same bell times. Use a single value for a normal fixed schedule.
3. Add periods and give each a name, a length, and how long the passing period after it should be. Add a lunch or break the same way.
4. Reorder periods with the up and down arrows, or remove any you do not need.
5. Print the schedule or save it as a PDF; each rotation day prints on its own page.

Leave Auto-calculate times on to let the tool derive every start and end time from the durations. Times use your device's 24-hour or 12-hour display; the schedule shows a clean 12-hour clock. All calculation happens locally in your browser — no accounts, no uploads.
