UK Working Days Calculator

Introduction

The UK Working Days Calculator counts Monday-to-Friday weekdays between two dates and lets you subtract bank holidays or closure days. It is useful for project lead times, HR planning, applications, and service-level estimates.

About this uk working days tool

Calendar days and working days answer different questions. A two-week period may contain ten weekdays, fewer if bank holidays or company closures fall inside it, and a different total for shift workers. This page gives a transparent weekday baseline that you can adjust.

How this tool works

Choose start and end dates, decide whether to include the end date, and enter the number of non-working holidays or closures to subtract. The calculator counts standard weekdays in the range and then applies your manual adjustment.

1. Choose the start date and end date.
2. Decide whether to include the end date in the count.
3. Enter any bank holidays or closure days to subtract from the weekday total.

When to use this tool

Use it when checking a project deadline, notice window, delivery estimate, leave period, or response target. It does not automatically fetch bank holidays by UK nation, so use an official holiday list when accuracy matters.

Good to know

• The calculator counts standard Monday-to-Friday weekdays and does not automatically fetch bank holidays.
• For shift patterns, use the result as a starting point and adjust for your rota.
