From 9 November 2026 to 9 December 2026 inclusive, the total is 23 business days.

Quick answer

9 November 2026 → 9 December 2026 = 23 business days

Both endpoints count when they’re working days. Saturdays, Sundays, and any weekday holidays you enter are excluded.

About This Business Days Calculator

The calculator counts Monday through Friday and includes both endpoints when they’re working days. A 30-day calendar span has 20 to 22 weekdays before holidays, depending on when it starts.

Enter the holidays that apply to your location or organisation. A date only reduces the total if it falls on a weekday within the selected range. If you need every date in the range, use Days Between Dates.

How to Calculate Business Days Between Two Dates

Pick your dates, enter any holidays you want to exclude, and select Calculate. To check the result by hand:

  • Count the calendar days, including the start and end dates.
  • Count five weekdays for each full week.
  • Add the weekdays in the leftover days.
  • Subtract the applicable holidays that fall on weekdays.

Business Days Formula

Business days = Calendar days − Weekend days − Weekday holidays

Each full week contributes five weekdays. For a rough estimate, multiply the inclusive calendar-day count by 5/7. The exact result depends on the weekdays in the partial week and the holidays you enter.

  • Typical month. 20 to 23 weekdays before holidays.
  • Typical year. 260 to 262 weekdays before holidays. 2026 has 261.

Frequently Asked Questions

Does the calculator include the start and end dates?

Yes. Both dates count if they are weekdays and you haven’t excluded them as holidays. Monday 2 November through Friday 6 November 2026 is 5 business days.

Are public holidays excluded?

Enter the dates that apply to your state, bank, or employer. The calculator subtracts each distinct weekday holiday within the range. A holiday that falls on a weekend is already excluded.

Is Saturday a business day in India?

It depends on the organisation. This calculator uses a Monday-to-Friday workweek. The RBI lists second and fourth Saturdays as bank holidays. For branch hours and other holidays, check the relevant RBI regional calendar and the bank.

How many working days are there in a month?

Usually 20 to 23 before holidays. November 2026 has 21 weekdays.

How many working days are there in a year?

A year has 260 to 262 weekdays before holidays. There are 261 weekdays in 2026. Subtract the weekday holidays that apply to you.

What is the difference between business days and calendar days?

Calendar days count every date. Business days follow a working schedule. This calculator counts Monday to Friday and excludes any weekday holidays you enter.

How do I find a date that is a certain number of business days away?

Start counting on the day after your starting date and skip weekends and applicable holidays. With no holidays excluded, 10 business days after Monday 9 November 2026 is Monday 23 November 2026.

Calculations use the Gregorian calendar and a Monday-to-Friday workweek. For holidays, check your state or organisation’s official list. For example, consult the central government office holiday list for Delhi and New Delhi or the RBI bank holiday calendar. Last updated .
