What is the Working Days Calculator?
A working days calculator is a tool that counts the number of business days (typically Monday–Friday) between two dates, with the option to exclude public holidays and custom days off. It removes weekends and specified non-working days from the total day count, giving you a realistic view of available working time.
How it works
The calculator takes your start and end dates, then counts each day in between. It automatically skips Saturdays and Sundays. If you add a list of holiday dates or custom non-working days (such as company shutdowns), the tool removes those too. The result is the number of actual working days you have to complete your project or meet your deadline.

Notes
Start: 1 January 2024, End: 31 January 2024, No holidays
22 working days
January 2024 has 23 days total, but removing 8 weekend days (4 Saturdays + 4 Sundays) leaves 22 business days.
Start: 15 April 2024, End: 30 April 2024, Holidays: 25 April (ANZAC Day)
12 working days
16 days minus 3 weekend days minus 1 public holiday = 12 working days available.
Start: 1 December 2024, End: 31 December 2024, Holidays: 25–26 Dec (Christmas break)
20 working days
31 days minus 8 weekend days minus 2 holiday dates = 20 working days for year-end planning.
How to use the Working Days Calculator
Enter your project start date in the first field (format: DD/MM/YYYY or use the date picker).
Enter your end date or deadline in the second field.
Add any public holidays or company days off in the 'Holidays' section (optional).
Click 'Calculate' to get the total number of working days.
Review the result; it automatically excludes all Saturdays, Sundays, and your custom holidays.
Export or note the figure for project scheduling, leave requests, or deadline negotiation.

Tips & common mistakes
Common mistakes
Forgetting to include all public holidays relevant to your country or region—check your calendar against national/local holiday lists.
Counting the start and end dates differently (e.g., including both vs. excluding one)—this calculator includes both by default; adjust manually if your policy differs.
Ignoring company-specific days off (summer shutdowns, training days, office closure dates)—add these to the holidays field for accuracy.
Using the result as clock hours: the calculator counts days, not hours; multiply by your working hours per day if you need a time estimate.
Tips
Create a reusable holiday list for your country or company and save it locally, so you don't re-enter dates every time.
For multi-phase projects, run the calculator separately for each phase and sum the working days for a full timeline.
If your team spans time zones or works non-standard shifts, note that this tool counts calendar days only; adjust results for split teams.
Cross-check the result with your project management tool (Jira, Asana, Monday.com) to spot any misaligned assumptions about working days.
Frequently asked questions
Does the calculator count the start date and end date themselves as working days?
Yes, by default both are included if they fall on weekdays. If either is a weekend or holiday, it is automatically excluded.
Can I add multiple holidays at once?
Yes, paste or type a comma-separated or line-separated list of dates in the holidays field, and the calculator will parse them.
What if my team works on Saturdays but not Sundays?
Most working days calculators assume Monday–Friday standard. For non-standard shifts, calculate your result manually or use a spreadsheet with custom day-of-week logic.
How do I calculate working hours, not just days?
Multiply your working days result by your hours-per-day (e.g., 22 days × 8 hours = 176 working hours), accounting for breaks and meetings as needed.
Is this tool accurate for salary and leave accrual calculations?
It gives a good starting point, but always verify against your employment contract and local labour laws, as rules vary by jurisdiction.
Can I exclude individual team members' holidays or vacation days?
This tool calculates company-wide working days. For per-person leave tracking, use an HR or calendar app (Google Calendar, Outlook) that integrates with your payroll system.
