Calculating Business Days

Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Calculating Business Days.

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)

ExcelTips is your source for cost-effective Microsoft Excel training. This tip (2155) applies to Microsoft Excel 97, 2000, 2002, and 2003. You can find a version of this tip for the ribbon interface of Excel (Excel 2007 and later) here: Calculating Business Days.

Hi I am working on a storage calculation. I have product being stored on day A, then I have 14 days free of charge and as from day 15 I can charge customer. Now I would like to have an overview of the payable days per month. Meaning if on Jan 25 I would store goods, there will be no invoice in Jan for these goods, but in Feb this would mean on the 29 I would be able to charge (31-25 =6 => 14-6 = 8) as of 8 feb till end of month, in this case 29th for this month.

Thx in advance.

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?
TIA

@Louis,
From Excel version 2010 and on - all you need is a simple formula like hereunder.

=NETWORKDAYS.INTL(Start_date,End_date,16)

It will calculate the amount of days (EXCLUDE Fridays) between to dates.

OK I need some help here. I have been trying to figure this one out and cant seem to get it. I need to calculate the time is takes for one of my agents to close a ticket that has been assigned to them. This needs to exclude holidays and weekends. My dates and times look like this:

Column O (opened) Column P (Closed)
2/27/2015 4:34:00 AM 3/10/2015 5:45:00 PM

(The time and date are in the same cell)

Here are the formulas that I have tried but none of them seem to be getting it right.

=(NETWORKDAYS(O2,P2)-1)*5/12+MOD(P2,1)-MOD(O2,1)
=NETWORKDAYS(O2,P2,Holidays!$A$2:$A$14)
=NETWORKDAYS(O2,P2)-1

Can anyone help??

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 need to calculate the difference between business days.
  
Cell A1 = 3/3/15
Cell B1 = 3/3/15
Cell C1 = NETWORKDAYS(A1,B1)

Cell C1 then populates with "1". When in reality it should be "0".

What is the function I can use to calculate the difference between business days?

I hope if someone here can help me with a formula where I want to get how many days it is due. I want to subtract due dates with the current day and keeps on updating or incrementing with 1 on the next day. And, using Excel 2013

Thanks to all who can help me with this in advance :)

@jc,
Assuming business days are Mon-Fri and your Excel version is earlier than 2010 and the 1st. Feb is in cells A1 and the 18th. Feb. in Cell B1, - try:
=NETWORKDAYS(A1,B1)
*** For this Function to work in old versions of Excel - you need to enable the "Analysis ToolPak" Add-In.

In 'Excel 2003' (and maybe even in 2000/2002) it works fine for me with all its arguments.
If you can't "standarditied" it - try

Thank you very much (Micky) Avidan,

However, my logic is I want employees to input their Leave start date in one column, then I want Excel to calculate 30 workdays from the start date and output the end date of their leave in the next column automatically.

Please see if you can help me out. I have been trying and experimenting with the DATE functions but cqant get the solution :(

I want a quick formula that can put in today's date and calculate what date it will be for business days. For example, I have a note that was done on 10/7/14 and I need to find out how to calculate what date it will be in 30 business days. I do not have a two date span. I want to find out what date it "will" be once I do the calculation. Thank you

If I have a start date and the duration is 2 days (indicated by a whole number is an adjacent cell), what formula do I use to find the end date which COUNTS the start date as one day, excluding holidays and weekends. This is for creating a schedule, and want to be able to change the "Duration" whole number and have it automatically calculate the new end date. Or have a start date and calculate the start date for the next task based on the days from previous task start date including that start date as Day 1.

@JKP,
if the "aware" date is in cell A1 and the amount of workdays to be added is in cell A2 -
type the following formula into cell A3: =WORKDAY(A1,A2)
and you should end up with the: March, 14, 2014.

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.
PhilP    07 Feb 2013, 12:57
Sara,

Add -1 to the end of the formula thus: =NETWORKDAYS(A3,A4)-1
Sara Talluto    06 Feb 2013, 15:11
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.
TJ    02 Jan 2013, 16:52
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.
