How to Count Working Days Between Two Dates | Itqan

Need the real number of working days between two dates? Leave balances, project delivery windows, and contract clauses that say “within X business days” all go wrong if you count calendar days alone. Weekends and public holidays pull the result off track. Itqan’s Working days between dates tool counts only real workdays — excluding weekends and holidays — or adds a number of business days to a start date to find the delivery day. This guide covers calendar vs business days, weekend patterns, Hijri holidays, four practical scenarios, an Excel comparison, a checklist, and FAQ — original content written for the platform’s users, not copied from generic blog posts.

What the tool does

It walks through every day in the range and classifies it as a working day, a weekend day, or a public holiday. The final answer is the number of real workdays, plus a breakdown of total days, weekend days, and working hours if you set hours per day. After you tap Result, a dedicated page shows the headline numbers, a short summary, a weekday distribution table, and the list of holidays excluded in the period — and you can save it as an image for sharing or filing.

This is different from the age calculator (years, months, and days of age) and the date converter (Hijri ↔ Gregorian without asking “how many workdays?”). Here the question is specific: How many working days fall between these two dates? or What is the delivery date after 10 business days?

The tool is built for offices, HR teams, project managers, and anyone who deals with contracts that say “within X business days.” You do not need Excel or a complex spreadsheet: open the page, set the weekend and holidays, and get a number you can stand behind with a client or your manager.

Calendar days vs working days

A calendar day is every day on the wall calendar — Sunday through Saturday. “From the 1st to the 14th” is always 14 calendar days, weekends included. A working day is a day your organization is expected to operate: not a weekend day and not a public holiday (according to your list).

Mixing the two causes frequent disputes. Example: “Deliver within two weeks” — does that mean 14 calendar days or about 10 business days? In many Gulf contracts and government procurement clauses, business days are intended; marketing promises often mean calendar days. Before you calculate, read the text carefully. If it says “working days” or “business days,” use this tool. If it only says “days” or “within 30 days,” check the policy before you rely on either number.

When you need business days

• HR: leave deducted in workdays, probation windows, resignation notice, or attendance days in a monthly sheet.
• Project management: delivery estimates that must skip weekends, plus review and handoff scheduling.
• Sales and contracts: clauses such as “within X business days of signing” or quote-response deadlines.
• Payroll: allowances or bonuses tied to working days inside a period.
• Government and education: statutory timelines counted in working days, not calendar days.
• Support and procurement: SLAs that only count business days toward resolution.

Whenever the question is “how many real workdays fall between these dates?” — not “how old am I?” or “what is the Hijri equivalent?” — this is the right tool.

How the calculation works

The logic is simple and transparent. Starting from the start date, the tool steps day by day to the end date (honoring your include-start / include-end options). For each day it asks three questions:

1. Is this day in your chosen weekend set? If yes → weekend, not a workday.
2. Is this date in your public/extra holiday list? If yes → holiday (unless it was already a weekend).
3. Otherwise → count one working day.

If a public holiday falls on a Friday or Saturday (depending on your pattern), it is not counted twice: it is excluded once as a weekend day. In Add business days mode, the tool walks forward from the start date, skipping non-workdays until the requested number of workdays is complete, then shows the arrival date and weekday name.

All of this runs locally in your browser — no file upload and no wait for a server to do the math — so the result is immediate and suitable for shared office devices once you follow the privacy notes at the end of this guide.

Weekend patterns by region

In many Gulf countries Friday and Saturday have been the common weekend; elsewhere, and in most international companies, Saturday and Sunday are standard. Some workplaces use a single weekend day (Friday only or Sunday only), or Thursday and Friday. Changing the weekend definition by even one day changes the workday count for any span longer than a week.

The tool ships ready-made patterns: Friday & Saturday, Saturday & Sunday, Thursday & Friday, Friday only, Sunday only, no weekend, or custom days you toggle with the weekday buttons. When you pick a country, a matching weekend and fixed-date holidays may be suggested — and you can still edit the days afterward if your workplace differs from the national norm.

Tip: do not assume “everyone here is off Friday–Saturday.” Tech teams serving European clients, international schools, and foreign bank branches often run Saturday–Sunday. Check the attendance policy or employment contract before locking the pattern.

Public and Hijri holidays

Fixed Gregorian holidays (such as a national day or New Year’s Day in some countries) can be added automatically when you select a country. Ramadan, Eid al-Fitr, and Eid al-Adha — and many other Islamic observances — follow the Hijri calendar and shift every year on the Gregorian calendar, so you add them manually, one date per line, as YYYY-MM-DD or DD/MM/YYYY.

Why are Hijri holidays not hard-coded for a given year? Moon-sighting and official announcements can differ by a day between countries, and the Hijri year is shorter than the solar year, so Eid “drifts” across the Gregorian calendar. The safest office workflow is to copy the holiday dates your organization (or the official gazette) adopted for that year and paste them into the extra-holidays field.

You can also add company-specific closures: founding day, maintenance shutdown, or an optional holiday announced by management. Each date line is excluded from workdays when it falls inside the range.

The two calculation modes

1) Between two dates

Enter a start date and an end date. The tool counts workdays in the span and also shows total calendar days and non-working days. Use this for leave balances, a project from–to window, or how many workdays sit inside a given month.

2) Add business days

Enter a start date and how many workdays you need. The result is the finish date and weekday. Use it for contract language such as “within 5 / 10 / 15 business days,” delivery promises, and response deadlines. This mode is close to Excel’s WORKDAY function, with a clearer UI and a flexible holiday list.

How to use it on Itqan

1. Open Working days between dates — no login required.
2. Choose the mode: Between two dates or Add business days.
3. Set the dates (or the number of workdays in add mode).
4. Pick a weekend pattern or toggle individual days.
5. Optionally choose a country for fixed-date holidays, then add Hijri and extra holidays one date per line.
6. In advanced options, adjust whether start and end days count, and set hours per day if you want an hours estimate.
7. Tap Result to open the result page.
8. Review the summary, table, and holiday list, then save as an image if you want to share or archive it.

Reading the result page

The result page matches the calculator’s look: headline cards for the main figures (workdays, and work weeks + leftover days when useful), then a summary of dates, weekend pattern, and detailed counts. Below that, a weekday distribution table shows how often Sunday, Monday, and so on fall in the range, and whether each weekday is treated as a workday or weekend under your settings. Finally, a list of holidays excluded in the period lets you confirm that Eid or the national day actually entered the math.

If a number looks “off,” start with the holiday list and the weekday table. The usual cause is a missing holiday or a weekend pattern that does not match the workplace — not a bad sum.

Counting start and end days

By default the tool counts the start day and the end day when they are workdays, matching Excel NETWORKDAYS and Google Sheets. Example: Monday through Friday in a week with no public holidays = 5 workdays, both endpoints included.

You can turn off start or end counting in advanced options when policy says “from the day after signing” or “until the day before departure.” That small switch changes the result by a full day — enough to create a leave-balance or last-working-day dispute if ignored.

Hours per working day

If you set hours per day (for example 8), the result estimates total working hours as workdays × hours per day. That helps for rough effort in a quote or for comparing one period with another. Remember it is a regular estimate: it does not subtract lunch breaks or add overtime. Fine-grained hour scheduling inside each day is outside the scope of “count working days.”

Practical scenarios — four common uses

Annual leave for two calendar weeks

An employee requests leave from the 1st to the 14th. The calendar says 14 days, but real workdays are fewer because of at least two weekend blocks. Open the tool, choose difference mode, enter both dates with Friday–Saturday (or your workplace pattern), and add any public holiday inside the span. The resulting number is often what HR deducts from the leave balance when policy uses workdays. Copy the result page or save an image to attach to the leave request.

Project delivery within 10 business days

A client wants delivery “within 10 business days” of signing on 26 July 2026. Switch to Add business days, enter the signing date and 10, and set holidays. You get the finish date with its weekday — useful for booking review, shipping, or a progress invoice. If Eid falls inside the window and you added it manually, the delivery date shifts automatically, so you avoid a calendar promise followed by an apology.

Resignation notice period

A contract requires 30 business days of notice. The employee resigns today and needs the last counted working day. Use add mode with 30 and the company holiday list for that period. Compare with HR policy: some workplaces start counting from the day after the notice is filed — in that case exclude the start day or begin from tomorrow explicitly.

Payroll: how many workdays in this month?

An accountant needs August workdays for a workplace that closes Friday–Saturday and has a national holiday mid-month. Enter the first and last day of the month, pick the country or paste holidays, and read the workday count. Multiply by a daily rate if payroll is daily, or compare with actual attendance from the time clock. The weekday table helps spot a “short” month caused by how weekends fall.

Compared with NETWORKDAYS and WORKDAY in Excel

The idea is the same: skip weekends and a holiday list. NETWORKDAYS counts workdays between two dates; WORKDAY adds workdays to a date. Itqan covers both jobs in one interface without a spreadsheet file, and shows a visual breakdown (summary + weekday table + holiday list) that is easier to review than a single cell.

Results match when the holiday list, weekend days, and endpoint rules match. If Itqan and Excel disagree, compare first: is Eid listed in both? Is one side Friday–Saturday and the other Saturday–Sunday? Is an endpoint excluded on one side only?

Common mistakes

• Mixing calendar days with working days: “Within two weeks” may mean 14 calendar days or about 10 workdays. Read the contract or policy first.
• Forgetting Hijri holidays: choosing a country alone does not cover Eid. Add Eid dates manually for each year you need.
• Reversing start and end: difference mode rejects an end date earlier than the start. Check the order before calculating.
• Assuming every workplace is Friday–Saturday: check your policy; some teams use Saturday–Sunday.
• Ignoring endpoint rules: one day on or off at the start or end is enough to dispute a leave balance.
• Pasting a Hijri date into a Gregorian field: the tool expects formal Gregorian dates. Convert with the date converter first if the source document is Hijri.
• Trusting the number without matching company policy: the tool follows your settings; internal rules may exclude half-days or local holidays you did not list.

Practical tips

• Keep the current year’s holiday list in a text note ready to paste into every new calculation during that year.
• When negotiating with an international client, agree in writing on what “business day” and which weekend mean before locking dates.
• Use save-as-image from the result page as an email attachment or support ticket instead of re-explaining the math.
• For long projects, split the span into phases and recalculate if holidays or policy change mid-way.
• For multi-country teams, run a separate calculation per branch weekend — do not blend patterns into one number.

Checklist before you rely on the result

• Do weekend days match workplace policy?
• Are Hijri and public holidays inside the period added?
• Should start and end days count under the contract?
• Do you need working days or calendar days?
• In add mode: does the count include the start day or begin the next day?
• Are dates Gregorian and in the correct order?
• Has someone else reviewed the number before it goes to a client or payroll?

FAQ

Summary

Working days are not the same as calendar days. Once you set the weekend and public holidays — and add Hijri holidays manually — Itqan gives a clear workday count or a delivery date after a set number of business days, with a detailed result page you can save and share. Align the number with your workplace policy and the contract’s definition of “business day” before you use it for payroll, leave, or client deadlines. Start now with Working days between dates.

Privacy

Dates and settings you enter are processed primarily in your browser to show the result. You do not need an account to count working days, and the tool does not ask for sensitive personal data such as a national ID to display the number. On a shared office PC: avoid saving result images that include employee names to a public folder, and clear browsing data if policy requires it.
