Business Days Calculator
Count the working days between two dates, or add and subtract business days from a date, with US, UK, Canada, Australia or France public holidays if you need them.
Both the start and end dates are counted when they are business days.
Holidays for 2026 to 2028 (Australia: 2026 and 2027). UK dates are for England and Wales.
Pick a start date and an end date to count the business days between them.
What is the Business Days Calculator?
A business day is a normal working day: Monday to Friday, leaving out public holidays. Banks, courts, couriers and most offices run on this calendar, so a deadline such as "within 10 business days" or "payment due in 30 working days" skips weekends and holidays. This calculator does that counting for you. It tells you how many business days fall between two dates, and it moves a date forward or back by a number of business days. Choose a country and its public holidays are taken out as well, for the United States, the United Kingdom, Canada, Australia or France. Some workplaces also open on Saturdays, so you can count Saturdays as working days too.
How to Use This Calculator
Count between dates: pick a start date and an end date. Both dates are counted when they are business days, so Monday to Friday of the same week gives 5. The result shows business days, calendar days and weekend days side by side, and lists every holiday it removed by name and date. Add or subtract days: pick a start date, type a number of business days and choose Add or Subtract. The start date itself is not counted, so day 1 is the next business day. You get the resulting date with its weekday and the number of calendar days it spans. In both modes, choose a country under Public holidays, and tick Count Saturdays as business days if your week runs Monday to Saturday.

Worked Examples
Two working weeks, no holidays
Count from Monday 2 November 2026 to Friday 13 November 2026, with Public holidays set to None.
- Calendar days
- 2 to 13 November, both included = 12
- Weekend days
- Sat 7 and Sun 8 November = 2
- Business days
- 12 − 2 = 10
10 business days (12 calendar days, 2 weekend days)
A week with Veterans Day
Count from Monday 9 November 2026 to Friday 13 November 2026, with United States holidays.
- Calendar days
- 9 to 13 November = 5
- Weekend days
- 0
- Public holidays
- Veterans Day, Wed 11 November = 1
- Business days
- 5 − 0 − 1 = 4
4 business days
Veterans Day is listed by name under the result. With Public holidays set to None, the same week counts as 5.
Adding 10 business days
Start on Monday 2 November 2026 and add 10 business days, with no holidays.
- Days 1 to 4
- Tue 3 to Fri 6 November
- First weekend skipped
- Sat 7 and Sun 8
- Days 5 to 9
- Mon 9 to Fri 13 November
- Second weekend skipped
- Sat 14 and Sun 15
- Day 10
- Mon 16 November
Monday 16 November 2026, 14 calendar days later
Subtracting 5 business days
Start on Monday 16 November 2026 and subtract 5 business days, with no holidays.
- Weekend skipped
- Sun 15 and Sat 14 November
- Days 1 to 5
- Fri 13, Thu 12, Wed 11, Tue 10, Mon 9
Monday 9 November 2026, 7 calendar days earlier
With United States holidays on, Veterans Day on the 11th is skipped as well, so the answer moves back to Friday 6 November.
Counting Saturdays
Count from Monday 2 November 2026 to Friday 13 November 2026, with Count Saturdays as business days ticked and no holidays.
- Calendar days
- 2 to 13 November = 12
- Weekend days
- Sun 8 November only = 1
- Business days
- 12 − 1 = 11
11 business days
Saturday 7 November now counts as a working day.
Why Use MyCalculatorsHub's Business Days Calculator?
Counting working days on a wall calendar is slow, and it is easy to slip across a month end or a bank holiday. This calculator works in both directions in one place. It shows the split between business days, weekend days and holidays so you can check the answer, and it names every holiday it took out. The holiday dates come from each government's own published list, with weekend substitute days applied. It runs in your browser, needs no sign up, and nothing you enter is sent to a server.
Common Mistakes to Avoid
The most common slip is counting the start date when you add days. If something is due 3 business days after a Monday, the answer is Thursday, not Wednesday, because day 1 is Tuesday. The opposite slip happens when counting between dates: people leave out one end, so Monday to Friday becomes 4 instead of 5. Another mistake is forgetting a holiday that lands on a weekend. In the US, the UK, Canada and Australia the day off often moves to the Friday before or the Monday after, so a weekday disappears. Finally, check whose holidays apply: Scotland and Northern Ireland have different bank holidays from England, and each Australian state adds its own.
Frequently Asked Questions
Does it count the start and end dates?
When you count between dates, yes. Both the start date and the end date are included if they are business days, so Monday to Friday of one week is 5 business days. When you add or subtract days, the start date is not counted: adding 1 business day to a Monday gives Tuesday.
Are public holidays included?
Only if you choose a country. With Public holidays set to None, only weekends are removed. Choose the United States, the United Kingdom, Canada, Australia or France and that country's public holidays inside your range are taken out too. Each one is listed by name and date under the result.
What if a holiday falls on a weekend?
The calculator follows each country's own rule. In the US, a Saturday holiday is taken on the Friday before and a Sunday holiday on the Monday after. The UK and Australia give a substitute weekday, usually the following Monday. In Canada, six of the federal holidays move to a working day, and we use the working day after. France does not move holidays, so one that lands on a weekend changes nothing.
Can I count Saturdays?
Yes. Tick Count Saturdays as business days and Saturdays count as working days in both modes. Sundays are always treated as days off. If a holiday falls on a Saturday while this is ticked, the Saturday itself is taken off instead of the substitute weekday.
How far ahead can I calculate?
Weekends are handled for any dates you enter. Public holidays are covered from 1 January 2026 to 31 December 2028 for the United States, the United Kingdom, Canada and France, and to 31 December 2027 for Australia, because the 2028 Australian dates are not published yet. If your range goes past the covered dates, the result tells you, and holidays outside them are not removed.
How We Calculate
Each date is turned into a whole day number, so time zones and daylight saving can't shift it. To count between dates, the calculator goes through every day from the start to the end, both included, and sorts each one into a weekend day, a public holiday or a business day. To add or subtract, it steps one day at a time from the start date, skipping weekend days and holidays, until it has counted the number of business days you asked for. Holiday dates come from official lists: OPM for US federal holidays, GOV.UK for England and Wales, the Canada Labour Code general holidays for Canada, the Fair Work Ombudsman for Australia and Service-Public.fr for France. Where a government gives a substitute day for a weekend holiday, we use it. For Canada, where the law allows the working day before or after, we use the day after.

Results are for planning. Your contract, industry or local area may add or move holidays, so check important deadlines with whoever set them.
