Count the weekdays between two dates, excluding weekends.
22 days
This calculator counts weekdays (Monday through Friday) between two dates, excluding Saturdays and Sundays -- useful for estimating shipping windows, project turnaround, or contractual "business days" deadlines. It counts calendar weekdays only; it does not exclude public holidays, since those vary by country, state, and employer.
Enter a start date and an end date. The result shows business days, weekend days, and the total calendar days in the range, counting both endpoints inclusively.
The tool walks each calendar day in the range and checks whether it falls on a Saturday or Sunday, tallying weekdays and weekend days separately. This day-by-day approach is exact for any date range, unlike formulas that estimate business days by dividing by 7.
Monday, January 5, 2026 through Sunday, January 11, 2026 (a full week) contains 5 business days and 2 weekend days.
To add a specific number of business days to a single start date (rather than counting between two known dates), use the Add Business Days Calculator. For a work-week breakdown across a longer span, see the Work Week Calculator.
Take Wednesday, January 7, 2026 through Tuesday, January 27, 2026. That span covers 21 calendar days, which is exactly three full weeks. Each week has 5 weekdays and 2 weekend days, so the result is 15 business days and 6 weekend days. Because the range is inclusive on both ends and 21 is a multiple of 7, the weekday count comes out cleanly. Now shift the end date to Wednesday, January 28: that is 22 calendar days, and the extra day is a weekday, so the total becomes 16 business days and 6 weekend days.
The tool does not know about public holidays, so adjust by hand. First run the calculation, then list every holiday within the range that falls on a weekday. Subtract each from the business day count. Holidays that land on a Saturday or Sunday are already excluded, so do not subtract them twice. Some employers observe a nearby weekday when a holiday falls on a weekend, so ask your employer or check the official calendar for your country or state.
Counting both endpoints is convenient for "how many working days does this range contain," but it is not always how a deadline is defined. If a contract says a payment is due within 5 business days of a notice, the notice day is often not counted, and the first counted day is the next business day. In that case, the Add Business Days Calculator is a better match, because it starts from the day after the start date. Use this tool when you want to know how much working time lies inside a known window.
The tool assumes a Monday to Friday work week. If your organization works on Saturdays or has a different weekend, the result will not match. It also cannot know about company shutdowns or regional observances. For legal deadlines, rely on the governing rule or an attorney rather than a general estimate.
No -- it counts calendar weekdays only. Holiday calendars vary too widely by country and employer to hardcode, so subtract known holidays from the result manually if needed.
Yes -- the range is inclusive of both endpoints, so a single weekday entered as both start and end counts as 1 business day.
The tool automatically swaps them so the count is always correct regardless of entry order.
Take the business days plus the number of Saturdays in the range, which you can estimate from the weekend days figure divided by two, then check the range boundaries manually.
The count includes both the start and end dates. If you do not want the start day included, subtract one when that day is a weekday.
Yes. Any Saturday or Sunday within the range, including on the first or last day, is tallied as a weekend day.
Yes, but check whether the carrier counts the order date, cutoff times, and holidays. Those rules differ between companies.
