Calculate the number of weekdays (Monday-Friday) between two dates.
Pick both dates to see the count.
This tool counts only the weekdays (Monday through Friday) between two dates, excluding Saturdays and Sundays -- useful for estimating business turnaround time or project timelines measured in working days.
Pick a start date and an end date. The number of weekdays between them appears instantly.
The calculator walks through every calendar date from the earlier of your two dates to the later one and counts each date that falls on Monday through Friday. Both the start date and the end date are included in the count. If you enter the dates in reverse order, the tool quietly swaps them, so you always get a positive result. Saturdays and Sundays are never counted, and no holiday calendar of any kind is applied.
Because the endpoints are inclusive, the result answers the question "how many weekdays fall on or between these two dates" rather than "how many working days have passed since the start." That difference of one day catches many people out.
These use hypothetical dates and a standard calendar where a week starts on Monday.
Public holidays vary by country, region and year, and some organizations observe additional company holidays. To adjust, count how many of those holidays fall on a weekday inside your date range and subtract them from the result. A holiday that lands on a Saturday or Sunday has already been excluded, so do not subtract it again. Check your government or employer's published holiday calendar rather than relying on memory, since observed dates sometimes shift when a holiday falls on a weekend. Leave, sick days and half days also need to be handled by hand.
This tool is for planning, not for legal or contractual determinations. Statutes, court rules, leases and employment contracts often define business days in specific ways, for example excluding particular holidays or counting from the day after an event. If a deadline has legal consequences, verify the counting rule in the document itself or consult a qualified professional, and confirm dates with the relevant official calendar.
No -- it counts Monday-Friday only. Public holidays vary by country and calendar year, so they aren't factored in; subtract known holidays manually from the result if needed.
Yes. If the start date is a weekday it is included in the total, and the same applies to the end date.
The tool swaps them automatically and counts the weekdays between the two dates, so the answer is the same in either order.
No. The tool always treats Saturday and Sunday as non-working days. If your schedule differs, count the days manually or use the total number of days between the dates as a starting point.
Subtract one from the result for each holiday that falls on a Monday to Friday date inside the range. Do not subtract holidays that fall on weekends.
