Weekend = Saturday + Sunday (Pakistan standard since 2022). Holidays you list are subtracted only when they fall on a weekday — a holiday on a Sunday is not double-counted.
A working days calculator is a simple date tool that counts how many business days fall between two dates. Instead of counting every calendar day, it skips the weekend and subtracts any holidays you specify, giving you the real number of days on which work actually gets done.
This distinction matters because deadlines, contracts, and project plans are almost always measured in working days rather than calendar days. Telling a client that a project takes "20 days" means something very different once weekends and public holidays are factored out.
Our calculator uses the standard Monday-to-Friday workweek, with Saturday and Sunday treated as the weekend. This matches the official weekend standard in Pakistan since 2022, when the federal government shifted the working week so that Saturdays and Sundays are the weekly off days. If your team works a different schedule, the results still give you a reliable baseline you can adjust from.
The tool goes one step further with an optional custom holiday list. Paste in dates in YYYY-MM-DD format, one per line, and the calculator removes those days from the working-day total as well. Because public holidays change every year and vary by country, company, and province, there are no hardcoded holiday claims inside the tool — you stay in complete control of which days count and which do not.
The logic behind the calculator is straightforward. You pick a start date and an end date, and the tool walks through every day in that range. Saturdays and Sundays count as weekend days. Any date in your holiday list counts as a holiday exclusion. Everything else counts as a working day.
One detail that trips people up is the end date: should the final day itself be included in the count? Our calculator includes an inclusive/exclusive toggle so you can decide. In inclusive mode, both the start and end dates are part of the count. In exclusive mode, the end date is treated as a boundary — the count stops the day before. Both conventions are common in contracts and HR policies, so having the choice avoids off-by-one disputes.
When you run the calculation, you get four clear outputs: the number of working days, the number of weekend days, the number of holidays excluded, and the total number of calendar days in the range. The four numbers always add up — working days plus weekend days plus holidays equals total calendar days — so the math is transparent.
Project managers are the classic users. When a milestone is due in "30 working days," this tool converts that commitment into a real calendar date, accounting for every weekend and holiday in between. It keeps sprint plans and delivery estimates honest.
HR teams and employees use it for leave calculation. Applying for annual leave or checking how many working days of leave you have taken is far simpler when holidays and weekends are excluded automatically rather than counted on a paper calendar.
Freelancers and contractors use working-day counts for billing. If you charge a day rate, the number of billable days in a month is the working-day count, not the calendar-day count — and being able to show a client exactly how you arrived at the number builds trust.
Contract and legal professionals rely on precise business-day counts for notice periods, delivery windows, and payment terms. The inclusive/exclusive toggle maps directly onto how these clauses are usually worded.
Students and teachers plan assignment timelines and term schedules around working days.
If you run a business that depends on precise scheduling — an agency, a consultancy, a software house — you probably also need a reliable online home for your company. FistHost shared hosting starts from just $0.99 per month, and every annual plan comes with a FREE domain, so you can get your business website online for less than the cost of a cup of tea.
Does the calculator include the end date in the count?
That depends on the toggle you choose. In inclusive mode, both the start and end dates are counted if they are working days. In exclusive mode, the end date is treated as a boundary and is not counted. Pick the setting that matches how your contract, policy, or deadline is worded.
Which days count as the weekend?
Saturday and Sunday. This follows the standard that has applied in Pakistan since 2022, where the official weekend is Saturday and Sunday and the working week runs Monday to Friday.
How do I add holidays?
Type or paste dates into the holiday box, one per line, in YYYY-MM-DD format — for example, 2026-03-23. Any working day in your range that matches a date on your list is subtracted from the working-day count and shown separately as a holiday exclusion.
What happens if a holiday falls on a weekend?
Days are categorized once: Saturdays and Sundays are always counted as weekend days, so a holiday on a weekend is not double-counted. The four result numbers always add up to the total calendar days.
Can I count working days in the past?
Yes. The start and end dates can be anywhere on the calendar — past, present, or future. This makes the tool useful both for reviewing how many working days a completed project took and for planning one that has not started yet.
Is the tool free to use?
Completely free, with no sign-up and no limits. Run as many calculations as you like, and pair it with our date duration calculator when you need the plain calendar-day difference, the countdown timer when you are tracking time left until a deadline, or the age calculator for personal date milestones.
