Working days & deadline calculator

Count the working days between two dates, or add working days to find a deadline — skipping weekends and England & Wales bank holidays. Handy for notice periods, invoice due dates and delivery promises.

Counts the days after the start up to and including the end date. Uses England & Wales bank holidays for 2025–2027 (Scotland and Northern Ireland differ). For dates outside that range, only weekends are excluded.

Built by Toolsmith Software — deadlines, SLAs and reminders that calculate themselves are a simple, high-value automation.
