Written by Golam Rabbani, Founder & Lead Engineer
How to use this employee scheduler
- Type an employee name in the "Add employee" field and press Add to create a row in the schedule grid.
- For each employee, enter a shift start time, end time, and optional label under each day (Mon–Sun).
- Set "Max weekly hours per employee" to the threshold at which you want an over-hours warning (default 40).
- Press "Calculate hours" to compute each employee's weekly total, flag conflicts, and show the grand total.
- Press Copy to save the plain-text summary to your clipboard, or Reset to clear all employees and shifts.
About this employee scheduler
The employee scheduler calculates each worker's scheduled hours across a Monday-to-Sunday week and flags anyone who exceeds a configurable limit.
For each shift the tool subtracts the start time from the end time in minutes. When the end time is earlier than the start time the scheduler treats the shift as overnight and adds 24 hours to the end before subtracting — so a 22:00–06:00 shift correctly yields 8 hours rather than a negative value. A shift is marked as a conflict (and excluded from the total) only if the start and end times are identical, which represents an ill-formed entry. The per-employee totals are summed to produce a grand total, and any employee whose hours exceed the max weekly hours threshold is highlighted in an amber warning.
Worked example: add two employees, Sam and Pat. Give Sam five day shifts, each 09:00–17:00 (8 h each), Monday through Friday — the tool counts 5 × 8 = 40.00 hrs for Sam. Give Pat one overnight shift on Saturday, 22:00–06:00 — that is 8 h crossing midnight, recorded as 8.00 hrs. The grand total is 48.00 hrs. With the max set to 40, Pat (8.00 hrs) is under the threshold and Sam (40.00 hrs) is exactly at it, so no over-hours warning fires for either.
Schedule data is saved automatically in your browser's localStorage, so the grid survives a page reload without any account or server.
FAQ
- What is the employee scheduler and what does it calculate?
- The employee scheduler is a browser-based tool that totals each employee's scheduled hours for a Mon–Sun week, flags shifts with identical start and end times as conflicts, and highlights any employee who exceeds the configured maximum weekly hours.
- Does the employee scheduler handle overnight shifts?
- Yes. When the end time is earlier than the start time, the tool automatically adds 24 hours to the end time before calculating the duration. A shift from 22:00 to 06:00 is correctly counted as 8 hours.
- What counts as a conflict?
- A shift is flagged as a conflict only when the start time and end time are identical (for example, both set to 09:00). That shift is excluded from the employee's weekly total and listed in the Conflicts column of the results table.
- Does the tool account for breaks or unpaid time within a shift?
- No. The scheduler calculates gross hours from the start time to the end time only. It does not subtract meal breaks or rest periods. Deduct any unpaid time manually from the shift times if needed.
- Can I export the schedule to CSV or another format?
- The tool does not produce a CSV file. After calculating, press the Copy button to place a plain-text "Employee Weekly Hours Summary" on your clipboard, which you can paste into a spreadsheet, email, or document.
- Is my schedule data stored on a server?
- No. The employee scheduler runs entirely in your browser and saves data only to your browser's localStorage. Nothing is sent to a server. Clearing site data or switching browsers will erase the saved schedule.
