Business Day Counter
Count working days between any two dates, with options to exclude weekends and US federal holidays.
Count working days between any two dates, with options to exclude weekends and US federal holidays.
A business day counter calculates how many working days fall between two dates. In the US, a business day normally means Monday through Friday, excluding weekends and, in many cases, federal holidays. Counting by hand is easy to get wrong across month boundaries and holiday weeks, so a calculator is useful whenever a deadline, notice period, or turnaround time is stated in business days rather than calendar days.
The answer depends on three things: whether the start date counts as day one, whether weekends are excluded, and which holidays are removed. A Monday-to-Friday span in the same week is 5 business days when the start date is included and 4 when it is not. Contracts, payment terms, shipping estimates, HR notice periods, and service level agreements may define business days differently, and some count only the days after the triggering event, so check the governing document. Holidays that land on a weekend usually create an observed weekday holiday, which can shift a count by one day.
To use this business day counter, choose a start date and an end date, then set the three options: Include start date (on by default), Exclude weekends (on by default), and Exclude US federal holidays (off by default). Press Calculate to see the total number of business days. The end date is always included, and if the dates are entered in reverse order the tool swaps them. The holiday option removes New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas on their observed weekday dates from 2024 through 2030.

The calculator automatically swaps them so the result is always positive.

Business days are weekdays — Monday through Friday — excluding Saturdays, Sundays, and public holidays. Counting them manually is tedious and error-prone, especially across month boundaries.
This calculator takes a start date and end date and automatically counts all weekdays between them. Options let you include or exclude the start date, skip weekends, and remove US federal holidays from the count.
Common uses include calculating contract terms (Net 30, Net 60), project timelines, payroll periods, SLA deadlines, and notice periods for legal and HR purposes.

| June | 20 | 21 | Juneteenth reduces count |
| July | 23 | 23 | July 4th reduces count |

Net 30 means payment is due 30 calendar days after the invoice date — this is calendar days, not business days, in most cases. However, some contracts specify business days. Always clarify the definition with your client.
Service level agreements often specify response and resolution times in business days. A '5 business day' SLA starting on a Friday ends the following Friday — the weekend days do not count.
Employment contracts, real estate transactions, and lease agreements frequently require notice periods in business days. Missing a deadline by even one day can have legal consequences — use this calculator to confirm exact dates.
When setting project milestones, working in business days avoids the common mistake of counting a weekend as productive time. A 20 business-day project starting Monday takes exactly 4 calendar weeks.
Count all calendar days between the two dates and subtract Saturdays and Sundays. If you also need to exclude public holidays, subtract those as well. This calculator does all of that automatically.
Two weeks (14 calendar days) equals exactly 10 business days, assuming no holidays fall within that period.
Yes. Toggle 'Exclude US federal holidays' to remove the 10 standard US federal holidays from the count. The calculator covers 2024, 2025, and 2026 holiday dates.
The 11 federal holidays are: New Year's Day (Jan 1), Martin Luther King Jr. Day (3rd Mon in Jan), Presidents' Day (3rd Mon in Feb), Memorial Day (last Mon in May), Juneteenth (Jun 19), Independence Day (Jul 4), Labor Day (1st Mon in Sep), Columbus Day (2nd Mon in Oct), Veterans Day (Nov 11), Thanksgiving (4th Thu in Nov), and Christmas (Dec 25).
They are typically the same thing — weekdays (Monday through Friday) excluding weekends and public holidays. Some industries define working days differently based on their operating schedule.
Most months have 20–23 business days depending on weekends and holidays. February usually has 20. March, May, July, August, and October typically have 23.
Enter your start date and then count forward only on weekdays. This calculator gives you the total count between two dates — to find an end date, you would count forward that many weekdays from your start.
By default, yes. Use the 'Exclude weekends' toggle if you need to include them for industries that operate 7 days a week, like hospitality or healthcare.
Yes. A federal holiday that falls on a Saturday is observed the Friday before, and one that falls on a Sunday is observed the Monday after. The holiday option removes the observed weekday, so Independence Day 2026 (Saturday, July 4) removes Friday, July 3.
2026 has 261 weekdays. Removing the 11 US federal holidays as observed leaves 250 business days, which is what the calculator returns for January 1 to December 31, 2026 with weekends and holidays excluded.
