Notice Period End Date Calculator

Advice for this situation

This calculator is most useful when someone is resigning, managing a handover, or trying to work out a likely final date without manually counting weeks and skipped days. In the UK, notice dates, leave dates, and business-day deadlines often depend on whether weekends count, whether bank holidays are excluded, and whether the contract sets a rule that is more specific than the default assumption.

Notice problems usually come from mixing up contractual notice, statutory notice, and last-day-on-site planning. If the date is contract-sensitive, check whether the relevant rule is calendar days, working days, or a fixed number of weeks, because those three approaches can land on different dates.

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.

• Check whether the notice rule comes from the contract, a policy, an award, or a statutory minimum.
• Confirm whether the clock starts on the day notice is given or the following day.
• If the role has annual leave booked near the end, keep the formal end date separate from the last actual working day.
