Choose the dates to count the working days.
Working days are the days that are not weekend days or holidays. Holidays: none built in. Confirm official dates before relying on them.
Working days calculator
Lets you pick a Friday–Saturday or six-day week, includes Pakistan, Gulf, US and UK holidays with Islamic dates shiftable for moon sighting, adds or subtracts working days, and turns the days into working hours and pay.
In short
Working days, or business days, are the days in a period that are not weekends or public holidays. In 2026 there are 261 weekdays and, with the 11 US federal holidays taken out, 250 working days. This calculator counts them between two dates, adds or subtracts working days, and lets you choose your weekend.

Private by design. Nothing you type is uploaded or saved. Add this tool to your phone or computer for one-tap access.
Holidays are only as good as the list. The built-in sets cover rule-based holidays; one-off days, regional holidays and moon-sighted Islamic dates are not guaranteed. For a contract, a visa or a legal deadline, confirm the exact days with the official notice.

How to use it
- Choose Days between dates, Add / subtract days, or Days in a year.

- Pick your weekend (Saturday–Sunday, Friday–Saturday, a six-day week or your own days) and a country’s public holidays if you want them.
- Add your own holidays, one per line, as 2026-12-25 or 25/12/2026.
- Read the working days, the holidays taken out, and the working hours. Download the day list as a CSV or copy the summary.
How it calculates
The tool walks through every calendar date in the range and counts the dates that are neither a weekend day (you choose which weekdays) nor a holiday. A holiday that falls on a weekend day is not counted twice. Adding or subtracting working days moves one working day at a time, skipping weekends and holidays; the start date itself is never counted. Working hours are working days times your daily hours less any unpaid break. US and UK holidays are generated by rule, including the substitute days. Islamic holidays are calculated from the Hijri calendar and can be shifted by up to two days for local moon sighting.
For example, Monday 19 to Friday 23 October 2026 with both ends counted is 5 working days. The whole of 2026 has 365 days and 261 weekdays; the 11 US federal holidays, with Independence Day observed on Friday 3 July, leave 250 working days. Thirty working days after 1 October 2026 is 12 November 2026. At 8 hours a day, 22 working days is 176 hours. The dates are made up; yours come from what you type.
Who should use it
- Employees and HR staff counting notice periods, leave and probation
- Anyone working out a delivery, payment-term or legal-deadline date in business days
- People in Pakistan and the Gulf, where the weekend and holidays differ from the Saturday–Sunday default
- Anyone asking how many hours they worked or will work in a period
Who should not use this
- Anyone who needs a legally binding deadline; confirm the exact days with the contract, court or authority, because definitions of “business day” differ
- Anyone who needs half days or clock-in times; use the timesheet calculator for hours worked
- Anyone who needs Hindu, Sikh or regional festival holidays or one-off closures; add those yourself
Limitations
- Built-in holidays cover only rule-based days. One-off bank holidays, regional holidays and festival days are not included; add them in your own list.
- Eid, Ashura and other Islamic holidays are calculated, and the government fixes the real days after moon sighting. Use the shift option or add the announced days yourself.
- The UK set is for England and Wales. Scotland and Northern Ireland have different bank holidays.
- Dates are counted as calendar days with no time zone or time of day.
- Nothing is uploaded or stored on a server. Clearing your browser data also removes the saved profile.

Common questions
How do I calculate the working days between two dates?
Count every date in the range, then take out the weekend days and the public holidays that fall on weekdays. Between Monday 19 and Friday 23 October 2026, with both ends counted, there are 5 working days. Enter the two dates here and the tool does the counting and lists the holidays it removed.
Is the start date counted as a working day?
In this tool, yes by default when you count between two dates, and you can untick either end. When you add working days to a date, the start date is not counted: one working day after a Friday is the next Monday.
How many working days are in a year?
2026 has 365 days and 261 weekdays (Monday to Friday). Taking out the 11 US federal holidays leaves 250 working days; with a Friday–Saturday weekend or a Sunday-only week the number is different. Use Days in a year to see each month.
How do I add business days to a date?
Choose Add / subtract days, enter the start date and the number of working days, and the tool moves forward one working day at a time, skipping weekends and holidays. Thirty working days from 1 October 2026 with no holidays is 12 November 2026.
What if my weekend is Friday and Saturday?
Pick Friday and Saturday in the Weekend list. This is the usual weekend in several Middle Eastern countries. A six-day week, with only Friday or only Sunday off, is also available, and you can choose any combination of days.
How many hours did I work in a month?
Count the working days in the month, then multiply by the hours in your day, less any unpaid break. Twenty-two working days at 8 hours is 176 hours. Enter your hours and break and the tool does the multiplication, and an hourly rate gives the pay. For clock-in times and overtime use the timesheet calculator.
Do holidays that fall on a weekend change the count?
No. A holiday on a day that is already a weekend day is not removed twice. Where a country moves the day off to a weekday, such as a US federal holiday observed on Friday or a UK substitute day, the tool uses the weekday.
How do I find my last working day after resigning?
Check whether your notice period is counted in calendar days or working days. For working days, add them to the date you gave notice. For calendar days, add them as ordinary days and the notice ends on that date, whatever day of the week it is.
