If you’re running a small business in the UK, knowing how many working days are in a month is more than just a trivia fact — it’s essential for scheduling, payroll, and ensuring your team stays on track. Whether you’re calculating deadlines or managing staff leave, understanding the distribution of working days throughout the year is key.

A working day typically refers to Monday through Friday, excluding weekends and public holidays. The exact number of working days in a month depends on these factors:

Total weekdays in the month

Why Is Knowing Working Days Important?

Payroll and invoicing: Accurate calculations for monthly wages and billing
Scheduling: Efficiently plan deadlines, projects, and team coverage
Leave management: Manage annual leave and public holidays, and ensure fairness across the team

Frequently Asked Questions (FAQs)

1. How many working days are in a month on average?

Typically, you can expect between 20 and 23 working days in a month, depending on public holidays and weekends.

2. Are Saturdays considered working days in the UK?

No, Saturdays are usually not counted as working days unless your business operates on weekends, such as in retail or hospitality sectors.

3. What happens if a public holiday falls on a weekend?

If a UK public holiday falls on a weekend, a substitute bank holiday is often observed on the following Monday.

4. Do part-time employees have the same number of working days?

No, part-time working days vary based on individual contracts. Employers typically prorate holidays and leave entitlements.

5. How do working days differ across UK regions?

While England and Wales share the same bank holidays, Scotland and Northern Ireland have additional holidays like St Andrew’s Day and St Patrick’s Day.

6. Can flexible workers have different working days?

Yes, employees with flexible or zero‑hours contracts may have varying working days.

7. How do leap years affect working days?

Leap years add an extra day in February, but since February 29 can fall on a weekend, it doesn’t always result in an extra working day.

How to Calculate Working Days (Step by Step)

If you prefer to do the maths manually:

Count the total days in the month (e.g., 31 for January)
Subtract weekends: Remove Saturdays and Sundays (typically 8–10 days per month)
Deduct public holidays: Check for bank holidays in your region
Adjust for regional variations: Some regions have extra holidays (like St Patrick’s Day in NI)

Example — May 2025 in England:

Total days: 31
Weekends: 9 (5 Saturdays + 4 Sundays)
Public holidays: 2 (Early May Bank Holiday and Spring Bank Holiday)
Working days: 31 − 9 − 2 = 20 working days

How to Calculate Working Days Using Excel

The NETWORKDAYS function in Excel (or Google Sheets) calculates the number of working days between two dates, excluding weekends (Saturday and Sunday) and optionally any holidays you specify.

=NETWORKDAYS(start_date, end_date, [holidays])

start_date: The start of the date range
end_date: The end of the date range
[holidays] (optional): A range of dates to be excluded from the working‑day count (e.g., public holidays)

Example 1 — Basic usage

=NETWORKDAYS("2024-02-01", "2024-02-28")

This counts all working days in February 2024, excluding weekends.

Example 2 — With holidays

Assume holidays are listed in cells C2:C4 (e.g., 2024-02-14, 2024-02-19, 2024-02-26):

=NETWORKDAYS("2024-02-01", "2024-02-28", C2:C4)

This calculates working days in February 2024, excluding weekends and the holidays in C2:C4.

Quick tips:

Both start_date and end_date are included in the calculation
For custom weekends, use NETWORKDAYS.INTL, where you can define which days are weekends
