Advice for this situation

This planner is for the common situation where the contractual end of employment and the last day you are actually in the workplace are not the same thing. 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.

People often talk about a last day without clarifying whether they mean the employment end date or the last day they are physically at work. 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.

  • Keep handover dates, equipment return, and payroll cutoffs separate from the contractual end date.
  • If annual leave is being used at the end, confirm it is approved before relying on the earlier finish date.
  • Use one version of the plan for HR and one for your own practical exit checklist if needed.

What you can enter
