What Is a Working Days Calculator?
A working days calculator counts only the weekdays that qualify as business days between two dates — ignoring non-work days. While a calendar days calculator counts Saturdays and Sundays, a business days calculator skips those by default (or any other days you configure as non-working).
This tool is essential for counting working days for contract notice periods, project milestone planning, HR and payroll calculations, legal deadlines, and government processing times — all of which are typically stated in business days rather than calendar days.
How to Count Working Days Between Two Dates
- 1Select your start date (the first day of the period to count).
- 2Select your end date (the last day of the period).
- 3Choose which days of the week count as working days — the Mon–Fri preset is selected by default.
- 4For non-standard work weeks (e.g., Sunday–Thursday in Middle Eastern countries), use the custom day buttons.
- 5Click "Calculate Working Days" to get the business days count, plus the number of non-working days.
- 6The result also shows equivalent working weeks and total calendar days.

Frequently Asked Questions
How do I calculate working days between two dates?
Enter your start date and end date, select which days of the week count as working days (default is Monday–Friday), and click "Calculate Working Days." The tool counts every day in the range that falls on a selected working day.
What is the difference between working days and calendar days?
Calendar days count every day including weekends. Working days (business days) only count the days you specify as work days — typically Monday through Friday. A 30-calendar-day range typically contains about 21–22 working days.
Does the working days calculator account for public holidays?
The calculator lets you configure your working week (any combination of days). For public holidays, subtract those manually from the result — different countries have different holiday schedules, and this gives you full flexibility.
How many working days are there in a month?
A typical 31-day month has approximately 21–23 working days, depending on how many weekends (and holidays) fall within it. A 28-day February typically has 20 working days. Use the calculator with the first and last day of any month to get the exact count.
How do I count business days for a contract deadline?
Set the contract start date as your start and your required notice period end as the end date. The calculator returns how many business days fall within that window. To find the deadline date itself, use the Date Calculator and add the number of business days you need.

This calculator excludes weekend days but does not automatically exclude public holidays, as these vary by country and region. Subtract your country's public holidays from the result manually.
