How It Works

Count the days that matter.

A working-days calculation starts with the full calendar date range, then excludes the weekly days off you select and any additional holidays that fall on otherwise working days.

01 / DATE RANGE

Choose your dates

Enter the first and last dates of your period. Both dates are included, so a single-day range contains one calendar day.

02 / WEEKENDS

Set your workweek

Choose Saturday and Sunday, Sunday only, Friday and Saturday, or no weekly days off to match your usual schedule.

03 / HOLIDAYS

Add specific holidays

Optionally enter public or company holiday dates. A holiday only reduces the working-day count when it falls on a working day within your selected range.

Working days formula

Working Days = Calendar Days − Weekend Days − Additional Working-Day Holidays

The calculator counts each date in the selected range once. Additional holidays that fall on weekends are already excluded as weekend days, so they are not deducted again. Dates outside the selected period have no effect on the result.

Everyday Planning

Where working-day calculations help.

Use a working-days estimate as a starting point for scheduling work, tracking deadlines, and planning business operations.

01

Project timelines

Estimate the working days available between a project start date and a target deadline, accounting for your chosen weekends and specified holidays.

02

Leave and attendance planning

Count potential working days within a leave period or planning window. Apply your organization's own leave and attendance rules separately.

03

Business operations

Estimate available workdays for scheduling, service delivery, invoicing cycles, reporting periods, and other recurring business tasks.

Frequently Asked Questions

Working Days Calculator FAQs.

A few important details about how the calculation works.

Are the start date and end date included?

Yes. The calculator includes both dates. If both dates are the same, the range contains one calendar day. That date counts as a working day only if it is not excluded by your weekend schedule or an additional holiday.

Does the calculator automatically exclude public holidays?

No. Public holidays vary by country, state, organization, and year. Enable the holiday option and add the dates relevant to your schedule. The calculator does not automatically retrieve an official holiday calendar.

Can I calculate working days for a Friday–Saturday weekend?

Yes. Select “Friday and Saturday” from the weekend schedule. Sundays through Thursdays will then count as working days, unless an added holiday excludes a date.

What happens when a holiday falls on a weekend?

The date is counted as a weekend day and is not deducted a second time as a holiday. This avoids double-counting the same excluded date.

Can I use this calculator for payroll or leave calculations?

You can use it for preliminary planning. Payroll, paid leave, overtime, attendance, and statutory working-day rules can differ by employer and jurisdiction. Verify the relevant policies before making official calculations.

Can I save or share the result?

Yes. Use “Copy Summary” to copy the calculation details, or select “Print / Save PDF” to open your browser's print dialog. From there, you can print the summary or choose a PDF destination if your browser supports it.
