Split shift time between standard and unsocial windows. This is a free calculator built for quick repeat checks on mobile and desktop.
Unsocial-hours tools help when part of a shift lands in an enhanced or awkward-hours window and you need a clean split. In the UK, unpaid lunch breaks normally only come out of paid time when you are genuinely relieved from work, average weekly hours are usually checked over a longer reference period, and overtime premiums often come from the contract rather than one universal statutory rate.
Unsocial-hours pay rules vary a lot between employers, so the time split is often more stable than the money outcome. If your workplace uses paid breaks, on-call time, or shift differentials, compare the calculator result with your rota rule before treating the number as payroll-ready.
UK guidance on this page is a practical planning layer, not legal advice. If the answer affects pay, dismissal, leave entitlement, or a formal workplace process, verify it against the contract, policy, collective rule, or official guidance that applies to your role.
