Guide: Hours Calculator
Compute net working hours from a start time, end time, and unpaid break. Helpful for freelancers, shift workers, and payroll sanity checks. Accurate hour logs underpin invoices, overtime eligibility, and labor-law disputes—small break mistakes compound across a month of shifts.

Night differential pay rules, if any, are policy-specific and not modeled here.
Paid vs unpaid breaks
Only subtract breaks your contract treats as unpaid. Some jurisdictions mandate paid short breaks after defined hours worked.
Rounding policies
Employers may round punches to the nearest quarter hour if allowed by law. Compare raw math here to your HR system’s rounding layer.
