Use the free Business Days Between Dates below: your data never leaves your browser — all work happens on your device, and nothing is uploaded to any server.
A calendar tells you how many days pass between two dates, but most work does not happen on every calendar day. Weekends sit in the middle of every project, every leave request, and every delivery promise. If you count plain days, you will overstate the time available and promise a deadline you cannot keep. The Business Days Between Dates tool fixes that by walking from the start date to the end date one day at a time and skipping Saturdays and Sundays, so the number you get is the number of working weekdays in the range.
This tool is built for everyday planning, not for programmers. You do not need a spreadsheet formula, an account, or an upload. Everything happens in your browser, on your own device. Your dates never leave the page, and nothing is sent to a server. That privacy matters little for two dates, but it is still the safest way to work online: the tool does its job and forgets your input when you close the page.
To use it, pick a start date and an end date. The tool reads both, and if you enter them in reverse order it still works, because it treats the earlier date as the start. Then choose whether the end date counts. Including both ends is the natural choice for a leave request that covers the last day too, while excluding the end date matches how many project tools measure a span. Press Count business days and the result shows three numbers: business days, weekend days, and total calendar days in the range, so you can check the maths at a glance.
One honest limit must be stated plainly. Public holidays are not subtracted, because they differ by country, region, and even employer. A bank holiday in one country is a normal working day in another, and no single list could cover every reader. Treat the result as working weekdays, then subtract your own local holidays by hand if you need exact leave days. For a two-week holiday, that usually means subtracting one or two days, and the tool gives you the clean weekday count to start from.
People use this count in several common jobs. Workers planning annual leave check how many leave days a trip really costs before they book flights. Project managers turn a calendar deadline into working days so a team knows how much effort fits. Freelancers quote delivery times in business days, which is what clients usually mean when they say next week. Teachers and parents count school days in a term, and anyone waiting on a delivery quoted in business days can check when it should really arrive.
A common mistake is to count the days on a calendar and then guess the weekends. For a short span the guess is often wrong by a day, and for a span crossing a month it can be wrong by much more. Another mistake is to forget that the start and end days themselves count. The tool removes both errors by walking day by day, including or excluding the end date exactly as you chose, and reporting the weekend days separately so the total always adds up.
The day-by-day method is deliberately simple, and that simplicity is its strength. A formula that divides by seven and adjusts for remainders is faster for a computer but harder to trust when you check it by hand. Walking each day is slow in theory and instant in practice for any span a person will actually plan, and every day is classified exactly once as a weekday or a weekend day. There is no rounding, no estimate, and no hidden assumption about which day the week starts on, because Saturday and Sunday are fixed.
Weekend rules are not the same everywhere, and the tool is honest about that too. In most of Europe and the Americas the weekend is Saturday and Sunday, and this tool follows that rule. In some countries the weekend falls on different days, and if that is your case, the count will not match your local working week. The tool is still useful for checking a plan written in the Saturday-Sunday convention, which is the one most international clients and suppliers use.

Frequently asked questions
Does it subtract public holidays? No. Holidays differ by country and region, so subtract your own holidays from the weekday count.
What if I enter the dates backwards? The tool still works. It treats the earlier date as the start.
Does the end date count? Only if you choose to include both ends. Pick the option that matches your plan.
Is my data uploaded? No. All counting happens in your browser.
