In performing calculations with Excel, it is often helpful to know how many days there are between two dates. Excel makes this easy—you just subtract the earlier date from the latter.

In a business environment, however, you may not want to know just the number of days—you probably want to know the number of business days between two dates. In other words, how many workdays are there between two dates?

Believe it or not, Excel makes it almost as easy to calculate business days as it is to calculate regular days. All you need to do is use the NETWORKDAYS worksheet function. This function is not intrinsic to Excel; it is part of the Analysis ToolPak. (How you enable the Analysis ToolPak is discussed in other *ExcelTips.*)

Let's suppose for a moment that you had two dates: one in A3 and the other in A4. The date in A3 is your starting date and the date in A4 is the ending date. To calculate the work days between the two dates, you could use the following formula:

=NETWORKDAYS(A3,A4)

This returns a count of all the days between the two dates, not counting weekends. You should note that the function returns the number of full days. Thus, if your starting date was Sept. 4 and your ending date was Sept. 5, the function would return a value of 2. (Provided neither day was a weekend day.)

If you want to account for holidays, the easiest way is to enter your standard holidays in a range of cells, and then define a name for that range. (I always like the terribly obvious name of "Holidays.") You can then alter the NETWORKDAYS formula in this manner:

=NETWORKDAYS(A3,A4,Holidays)

Hello,

I appreciate your insight. Very helpful.

I am working for a home loan institution and I have been tasked to create a spreadsheet that will allow us to calculate the estimated closing date of a loan according to business days.

We have the start date(date of application), but here's where it can get tricky. Each portion of the loan process can last a different number of days. For instance gathering the initial documents takes 4-7 days depending on the customer. Then the paperwork is submitted which is time variable as well. There are about 15 stages to the loan process which we are trying to represent in the sheet.

Ideally we would like to be able to enter a start date, enter an ideal close date, then enter each of the loan stage names and a number of days each ideally takes, and equal a closing date.

If one stage gets delayed, we would like to be able to change the # of days and have it automatically change the closing date.

If I can get this right it will create a job for me at this institution. Please help!

I came across an issue counting Working Days or Business Days which appears to be related to & only effecting the month of Dec after claendar year 2015 (counts for Working Days in Dec 2014 are correct).

There should be 23 Working Days in Dec 2015, but all of a sudden my formula calcs as 24 (was correct in prior months & years). Here is my formula:

=NETWORKDAYS(EOMONTH(todaysDate,-1),EOMONTH(todaysDate,0))

Am i doing something wrong or is this a new/known issue?

Hi

I need help.

I have a formula in Excel that calculates each day someone is off sick from work and stops counting once you enter a return to work date.

However, I need the formula to discount weekends.

Now I'm aware of the "=NETWORKDAYS.INTL..." function.

The current formula I have enables me to calculate the number of days someone is off sick and effectively stops the clock once you enter a return to work date.

So what formula/function calculates the number of days someone is off sick, stops the clock once you enter a return to work date but also excludes weekends?

Kind Regards

I am trying to add 30 business days to an "aware" date (in this case it's Jan 31 2014) to calucale a "due date". can you help me with the calculation?

Although this tip is intended for "97-2007" users - all "Modern" users should be aware that starting with "Excel 2010" there is an extended NetWorkdDays Function: NETWORKDAYS.INTL

The following formula calculates the working days' between two given dates, excluding Fri-Sat.

=NETWORKDAYS.INTL(A3,A4,7)

One should check "Excel" Help for, so called, excluded "weekends" options.

I had a challenge because of a business process wrinkle. They wanted monthly SLA averages of ticket times, but only wanted to charge the help desk for time spent between 7:00am and 5:00pm.

The most direct solution I could devise was to use NETWORKDAYS to add the time for the first day, the time of the last day, and 10 x the count of the days in between.

NETWORKDAYS made it easy to eliminate weekends and holidays, but I had to devise error checking in the formula and limit one day responses to not include additional time.

Sara,

Add -1 to the end of the formula thus: =NETWORKDAYS(A3,A4)-1

Add -1 to the end of the formula thus: =NETWORKDAYS(A3,A4)-1

You said this function counts the number of full days "Thus, if your starting date was Sept. 4 and your ending date was Sept. 5, the function would return a value of 2"

Is there a function to use that would not count the start date as a day?

I work at a test lab, and I have to calculate how many days tests were started late. So if the start date was Sept. 4 and the end date was Sept. 5, I need to show that the test started one day late. Any advice will be helpful.

If this tip does not work on your spreadsheet, you need to do the following:

Go to: Tools ---> Add Ins, then turn on Anaysis ToolPak.

After the Analysis ToolPak installs, re-type the formula and it should work just fine.
