Workdays between two dates
Count the working days between any two dates, weekends excluded, with the calendar-day total alongside. The start day is not counted and the end day is, which matches how deadlines are usually phrased.
Counting business days without off-by-one mistakes
Most workday disputes are really convention disputes. If a contract says payment is due ten working days after delivery, the question is whether delivery day itself counts. The near-universal convention, and the one used here, is that it does not: counting starts the next day and the deadline day is included. Five working days from a Monday is the next Monday, not Friday.
The other classic mistake is estimating with calendar weeks. Thirty calendar days sounds like a month of work but usually contains only 21 or 22 working days, and a project plan built on the wrong number quietly loses a week. This calculator shows both figures side by side so the gap is visible instead of surprising.
Weekends are Saturday and Sunday here. Some countries work Sunday to Thursday, and public holidays shift the count everywhere, so treat the result as the standard international baseline and adjust for local holidays when precision matters. If you need the reverse operation, the add-workdays calculator starts from a date and walks forward or back.
FAQ
Is the start date counted?
No. The count runs from the day after the start date through the end date, inclusive. "Five working days from Monday" therefore lands on the following Monday, which is how most deadlines are meant.
Are public holidays excluded?
Not yet. Holidays differ by country and even by region, so this calculator sticks to the universal rule of skipping Saturdays and Sundays, and says so rather than silently guessing your country. Holiday-aware counting per country is planned.
Can I count backwards?
Yes. Put the later date first and the result shows the working days between them just the same.
