🤔 How Does This Work?
The Working Days Calculator counts business days by looping through each day between your two dates:
For each day, it checks if it is a weekday (Monday=1 through Friday=5)
If you include Saturdays or Sundays, those days are also counted
Any dates you add to the holiday list are subtracted from the total
The result shows working days, calendar days, and weekend days separately
This is useful for project planning, delivery time estimates, payroll calculations, and leave management.

❓ FAQ
What is a working day?▼
A working day (also called a business day) is any day that is not a weekend (Saturday or Sunday) and not a public holiday. In most countries, working days are Monday through Friday. Some countries count Saturday as a working day.
How do I calculate working days for a project deadline?▼
Enter your project start date and deadline date. The calculator counts all weekdays between them, excluding weekends. Add your country's public holidays to get the exact number of working days available.
How are working days different from calendar days?▼
Calendar days count every day including weekends and holidays. Working days only count weekdays (Mon-Fri, excluding public holidays). A 30-calendar-day period typically contains about 22 working days.
How do I calculate annual leave remaining?▼
If your company gives 21 working days of annual leave and you have used 14 days, you have 7 working days remaining. Our calculator helps you find how many working days fall in your remaining leave period.
Do all countries have the same working days?▼
No. Most Western countries work Monday to Friday. Some Middle Eastern countries (like UAE) work Sunday to Thursday. Some retail and service workers work weekends. Our calculator lets you customise which days to count.
