How to use the working days calculator

  1. Choose the start and end date. Both days are included in the count.
  2. Choose the days you work. Monday to Friday is selected by default. Tap a day to switch it on or off, for example for a six-day week or a Tuesday–Saturday shift pattern.
  3. Enter the number of public holidays that fall on your working days in the period.

You get the number of working days, the calendar days, the days off and the working hours based on an 8-hour day.

How it is calculated

working days = days in the period that are on your working days − public holidays on those days

The calculator goes through every date in the period and checks whether its weekday is one of your working days. It then subtracts the holidays you entered.

Worked example

December 2026 runs from Tuesday 1 to Thursday 31 December. It has 31 calendar days, of which 23 are weekdays (Monday–Friday).

  • In England, Christmas Day (Friday 25 December) and Boxing Day, observed on Monday 28 December, are bank holidays. 23 − 2 = 21 working days.
  • In Germany, 25 and 26 December are public holidays, but the 26th falls on a Saturday. 23 − 1 = 22 working days.

Public holidays by country

Public holidays differ by country and often by region. In the UK, England, Scotland and Northern Ireland have different bank holidays. In Germany they vary by state (Bundesland). In the US, federal holidays apply to government offices, but private employers set their own. Check your official government holiday list and count the holidays that fall on your working days.

Typical uses

  • Delivery times and legal deadlines given in "business days".
  • Working out pro-rata pay or holiday entitlement for part of a month.
  • Project planning: how many working days are left before a launch.

Frequently asked questions

Are the start and end dates included?
Yes. Both dates count if they fall on one of your working days.
Does the calculator know public holidays?
Not automatically, because they depend on your country and region. Enter the number of holidays that fall on working days in your period, and they will be subtracted.
How many working days are in a year?
A year has about 260–262 weekdays. After public holidays this is usually 250–254 working days, depending on the country and how the holidays fall.
Can I count a six-day working week?
Yes. Tap Saturday to add it to your working days. You can choose any combination of days.
