Work & Hours Tools

Shift math has traps: shifts that cross midnight, unpaid breaks, and payroll systems that expect decimal hours (7.5) while timesheets show 7:30. These tools handle overnight spans explicitly, subtract breaks from gross duration, and document their rounding so you know exactly what a number means.

Frequently asked questions

How is an overnight shift handled?

If the end time is not after the start time, the tool treats the shift as crossing midnight and adds 24 hours to the elapsed duration. The result is labeled as an overnight span so you can sanity-check it.

Is this a payroll or labor-law compliance tool?

No. It is a calculator for durations. It does not apply overtime rules, minimum-wage law, collective agreements, or rounding regulations; check those with your payroll provider or HR team.

What rounding is used for decimal hours?

Decimal results are displayed rounded to two decimal places for readability, and the exact minutes are always shown alongside so you can verify. Converting hours:minutes to decimal uses exact arithmetic; 7:30 is exactly 7.5.
