How to use this result
The tool includes both dates, separates your ordinary non-working days and then excludes applicable holidays on working days. Additional non-working dates are deduplicated, so a date is never subtracted twice.
A leave request still needs to be checked against the employee’s balance, policy and actual roster. This tool counts whole days and does not calculate shift hours, half-days or entitlement.
Keep the assumptions visible
Use an estimate to start a conversation, then reconcile it with the organisation’s verified leave record. Irregular schedules, changes in service and special contractual arrangements need separate consideration.
