Terms of use

Use the tools for personal or authorized planning. Check inputs and downloaded schedules before use. The tools do not determine labour-law compliance, overtime pay or medical suitability for a shift.

The time-zone database is supplied by your browser. Clock changes and local rules can affect results. The tool supports dates from 2000 through 2100, up to 366 rows and files up to 64 KB. A full-day shift is at most 24 elapsed hours.

Results can be removed when browser storage is cleared and expire after 24 hours. No uptime, search ranking, advertising approval or income is guaranteed. Report a calculation error through the contact page with a non-sensitive example.
