# How to Calculate Business Days in a Month in Excel (Formula)

- Written by Puneet

To get the total number of business days (working days) in Excel using a formula, you need to combine two functions (EOMONTH and NETWORKDAYS). In this formula, EOMONTH helps you to get the last date of the month, and by using that last date and the first date specified by you, NETWORKDAYS returns the total number of business days in a month.

In this tutorial, we will learn to write this formula. And we will also consider holidays that you need to specify while calculating the total days.

## Excel Formula to Get Total Business Days in a Month

You can use the below steps:

1. First, in a cell, enter the NETWORKDAYS function.
2. After that, in the first argument (start_date) refer to the cell where you have the starting date of the month.
3. Next, in the second argument, (end_date) enter the EOMONTH function.
4. From here, in the EOMONTH, specify the starting date of the month that you have referred to in the start_date argument of the NETWORKDAYS.
5. Now, enter zeros (0) in the (months) argument of the EOMONTH, and type closing parentheses to close the function.
6. In the end, refer to the list of holidays (this needs to be a list of valid dates) in the [holidays] argument of the NETWORKDAYS, type the closing parentheses, and hit enter to get the result.
``````=NETWORKDAYS(A1,EOMONTH(A1,0),A4:A14)
=NETWORKDAYS(start_date,EOMONTH(start_date,0),list_of_holidays)``````

## How Does This Formula Works?

As I mentioned earlier, the EOMONTH function returns the last date of the month. When you specify a date in the function, it returns the last date of that month.

NETWORKDAYS uses that date as an ending date to get the total number of days between these two dates.

And in the end, when you specify a list of dates that are holidays. NETWORKDAYS also considers that while calculating the total number of days.

In the example above, we have used the first day of January month of 2023. In January, we have 31 days in total. And when you check it manually, you have 10 weekends and holidays in the month. That means 21 working days for a business.

And that’s the exact number of business days we have got in the result.
