*In this tutorial, you will find a simple explanation of the Excel DATEDIF function and a few formula examples that demonstrate how to compare dates and calculate the difference in days, weeks, months or years.*

Over the past few weeks, we investigated nearly every aspect of working with dates and times in Excel. If you have been following our blog series, you already know how to insert and format dates in your worksheets, how to calculate days, weeks, months and years as well as add and subtract dates.

In this tutorial, we will focus on calculating date difference in Excel and you will learn different ways to count the number of days, weeks, months and years between two dates.

## Excel DATEDIF function - calculating date difference

As its name suggests, the DATEDIF function is purposed for calculating the difference between two dates.

DATEDIF is one of very few undocumented functions in Excel, and because it is "hidden" you won't find it on the *Formula* tab, nor will you get any hint on which arguments to enter when you start typing the function's name in the formula bar. That is why it's important to know the complete syntax of Excel DATEDIF to be able to use it in your formulas.

#### Excel DATEDIF function - syntax

The syntax of the Excel DATEDIF function is as follows:

All three arguments are required:

**Start_date** - the initial date of the period you want to calculate.

**End_date** - the ending date of the period.

To put it differently, start_date and end_date are two dates to calculate the difference between. In your DATEDIF formulas, you can input the dates is various ways, such as:

- Cell references. For example, the following formula counts the number of days between the dates in cells A1 and B1:
`=DATEDIF(A1, B1, "d")`

- Text strings. Excel understands dates in many formats, for example "20-May-2015", "5/20/2015", "2015/5/20", etc. The following formula calculates the number of months between the specified dates:
`=DATEDIF("5/10/2015", "7/20/2015", "m")`

- Serial numbers. Since Microsoft Excel stores each date as a serial number beginning with January 1, 1900, you can put numbers corresponding to the dates directly in the formula. Although fully supported, this method is not reliable because date numbering varies on different computer systems. In the 1900 date system, the following formula is another way to calculate months between two dates from the previous example (10-May-2015 and 20-Jul-2015):
`=DATEDIF(42134, 42205, "m")`

- Results of other functions. For instance, the following formula counts how many days there are between today's date and 20 May, 2015.
`=DATEDIF(TODAY(), "5/20/2015", "d")`

**Note.**In your formulas, the end date must always be greater than the start date, otherwise the Excel DATEDIF function returns the #NUM! error.

**Unit **- the time unit to use when calculating the difference between two dates. By supplying different units, you can get the DATEDIF function to return the date difference in days, months or years. Overall, 6 units are available, which are described in the following table.

Unit | Meaning | Explanation |

Y | Years | Number of complete years between the start and end dates. |

M | Months | Number of complete months between the dates. |

D | Days | Number of days between the start date and end date. |

MD | Days excluding years and months | The date difference in days, ignoring months and years. |

YD | Days excluding years | The date difference in days, ignoring years. |

YM | Months excluding days and years | The date difference in months, ignoring days and years. |

Hopefully, the above information has been helpful to understand the basics. And now, let's see how you can use the Excel DATEDIF function to compare dates in your worksheets and return the difference.

## How to get the number of days between two dates in Excel

If you observed DATEDIF's arguments carefully, you've noticed that there exist 3 different units for counting days between the dates. Which one to use depends on exactly what your needs are.

#### Example 1. Excel DATEDIF formula to calculate date difference in days

Supposing you have the start date in cell A2 and the end date in cell B2 and you want Excel to return the date difference in days. A simple DATEDIF formula works just fine:

`=DATEDIF(A2, B2, "d")`

Provided that a value in the start_date argument is less than in end_date. In case the start date is greater than the end date, the Excel DATEDIF function returns the #NUM error, as in row 5:

If you are looking for a formula that can return the date difference in days as either a positive or negative number, simply subtract one date directly from the other:

`=B2-A2`

Please see How to subtract dates in Excel for full details and more formula examples.

#### Example 2. Count days in Excel ignoring years

Supposing you have two lists of dates that belong to different years and you wish to calculate the number of days between the dates as if they were of the same year. To do this, use a DATEDIF formula with "YD" unit:

`=DATEDIF(A2, B2, "yd")`

If you want the Excel DATEDIF function to ignore not only years but also moths, then use the "md" unit. In this case, your formula will calculate days between two dates as if they were of the same month and the same year:

`=DATEDIF(A2, B2, "md")`

The screenshot below demonstrates the results, and comparing it with the screenshot above can help understand the difference better.

**Tip.**To get the number of

**working days**between two dates, use the NETWORKDAYS or NETWORKDAYS.INTL function.

## How to calculate date difference in weeks

As you probably noticed, the Excel DATEDIF function does not have a special unit to calculate date difference in weeks. However, there is an easy workaround.

To find out how many weeks there are between two dates, you can use the DATEDIF function with "D" unit to return the difference in days, and then divide the result by 7.

To get the number of **full weeks** between the dates, wrap your DATEDIF formula in the ROUNDDOWN function, which always rounds the number towards zero:

`=ROUNDDOWN((DATEDIF(A2, B2, "d") / 7), 0)`

Where A2 is the start date and B2 is the end date of the period you are calculating.

## How to calculate the number of months between two dates in Excel

Similarly to counting days, the Excel DATEDIF function can compute the number of months between two dates that you specify. Depending on the unit you supply, the formula will produce different results.

#### Example 1. Calculate complete months between two dates (DATEDIF)

To count the number of whole months between the dates, you use the DATEDIF function with "M" unit. For example, the following formula compares the dates in A2 (start date) and B2 (end date) and returns the difference in months:

`=DATEDIF(A2, B2, "m")`

**Note.**For the DATEDIF formula to calculate months correctly, the end date should always be greater than the start date; otherwise the formula returns the #NUM error.

To avoid such errors, you may force Excel to always perceive an older date as the start date, and a more recent date as the end date. To do this, add a simple logical test:

`=IF(B2>A2, DATEDIF(A2,B2,"m"), DATEDIF(B2,A2,"m"))`

#### Example 2. Get the number of months between two dates ignoring years (DATEDIF)

To count the number of months between the dates as if they were of the same year, type "YM" in the unit argument:

`=DATEDIF(A2, B2, "ym")`

As you see, this formula also returns an error in row 6 where end date is less than the start date. If your data set may contain such dates, you will find the solution in the next examples.

#### Example 3. Calculating months between two dates (MONTH function)

An alternative way to calculate the number of months between two dates in Excel is using the MONTH function, or more precisely a combination of MONTH and YEAR functions:

`=(YEAR(B2) - YEAR(A2))*12 + MONTH(B2) - MONTH(A2)`

Of course, this formula is not so transparent as DATEDIF and it does take time to wrap your head around the logic. But unlike the DATEDIF function, it can compare any two dates and return the difference in months as either a positive or negative value:

Notice that the YEAR/MONTH formula has no problem with calculating months in row 6 where the start date is more recent than the end date, the scenario in which an analogues DATEDIF formula fails.

**Note.**The results returned by DATEDIF and YEAR/MONTH formulas are not always identical because they operate based on different principles. The Excel DATEDIF function returns the number of

**complete calendar months**between the dates, while the YEAR/MONTH formula operates on months' numbers.

For example, in row 7 in the screenshot above, the DATEDIF formula returns 0 because a complete calendar month between the dates has not elapsed yet, while YEAR/MONTH returns 1 because the dates belong to different months.

#### Example 4. Counting months between 2 dates ignoring years (MONTH function)

In case all of your dates are of the same year, or you want to calculate months between the dates ignoring years, you can the MONTH function to retrieve the month from each date, and then subtract one month from the other:

`=MONTH(B2) - MONTH(A2)`

This formula works similarly to Excel DATEDIF with "YM" unit as demonstrated in the following screenshot:

However, the results returned by two formulas differ is a couple of rows:

- Row 4: the end date is less than the start date and therefore DATEDIF returns an error while MONTH-MONTH yields a negative value.
- Row 6: the dates are of different months, but the actual date difference is just one day. DATEDIF returns 0 because it calculates whole months between 2 dates. MONTH-MONTH returns 1 because it subtracts the months' numbers from each other ignoring days and years.

## How to calculate years between two dates in Excel

If you followed the previous examples where we calculated months and days between two dates, then you can easily derive a formula to calculate years in Excel. The following examples can help you check if you got the formula right :)

#### Example 1. Calculating complete years between two dates (DATEDIF function)

To find out the number of complete calendar years between two dates, use the old good DATEDIF with the "Y" unit:

`=DATEDIF(A2,B2,"y")`

Notice that the DATEDIF formula returns 0 in row 6, although the dates are of different years. This is because the number of full calendar years between the start and end dates equals to zero. And I believe you are not surprised to see the #NUM! error in row 7 where the start date is more recent than the end date.

#### Example 2. Calculating years between two dates (YEAR function)

An alternative way to calculate years in Excel is using the YEAR function. Similarly to the MONTH formula, you extract the year from each date, and then subtract the years from each other:

`=YEAR(B2) - YEAR(A2)`

In the following screenshot, you can compare the results returned by the DATEDIF and YEAR functions:

In most cases the results are identical, except that:

- The DATEDIF function calculates complete calendar years, while the YEAR formula simply subtracts one year from the other. Row 6 illustrates the difference.
- The DATEDIF formula returns an error if the start date is greater than the end date, while the YEAR function returns a negative value, as in row 7.

## How to get date difference in days, months and years

To count the number of complete years, months and days between two dates in a single formula, you simply concatenate three DATEDIF functions:

`=DATEDIF(A2, B2, "y") &" years, "&DATEDIF(A2, B2, "ym") &" months, " &DATEDIF(A2, B2, "md") &" days"`

If you'd rather not display zero values, you can wrap each DATEDIF in the IF function as follows:

`=IF(DATEDIF(A2,B2,"y")=0, "", DATEDIF(A2,B2,"y") & " years ") & IF(DATEDIF(A2,B2,"ym")=0,"", DATEDIF(A2,B2,"ym") & " months ") & IF(DATEDIF(A2, B2, "md")=0, "", DATEDIF(A2, B2, "md") & " days"`

The formula displays only non-zero elements as demonstrated in the following screenshot:

## DATEDIF formulas to calculate age in Excel

In fact, calculating someone's age based on the date of birth is a special case of calculating date difference in Excel, where the end date is today's date. So, you use a usual DATEDIF formula with "Y" unit that returns the number of years between the dates, and enter the TODAY() function in the end_date argument:

`=DATEDIF(A2, TODAY(), "y")`

Where A2 is the birth date.

The above formula calculates the number of complete years. If you'd rather get the exact age, including years, months and days, then concatenate three DATEDIF functions like we did in the previous example:

`=DATEDIF(B2,TODAY(),"y") & " Years, " & DATEDIF(B2,TODAY(),"ym") & " Months, " & DATEDIF(B2,TODAY(),"md") & " Days"`

And you will get the following result:

## Date & Time Wizard - easy way to build date difference formulas in Excel

As demonstrated in the first part of this tutorial, Excel DATEDIF is quite a versatile function suitable for a variety of different uses. However, there is one significant drawback - it is undocumented by Microsoft, meaning, you won't find DATEDIF in the list of functions nor will you see any argument tooltips when you start typing a formula in a cell. To be able to use the DATEDIF function in your worksheets, you have to remember its syntax and enter all the arguments manually, which might be a time-consuming and error-prone way, especially for beginners.

Ultimate Suite for Excel changes this radically as it now provides the *Date & Time Wizard* that can make almost any date difference formula in no time. Here's how:

- Select the cell where you want to insert the formula.
- Go to the
*Ablebits Tools*tab >*Date & Time*group, and click the**Date & Time Wizard**button:

- The
*Date & Time Wizard*dialog window shows up, you switch to the**Difference**tab and supply data for the formula arguments:- Click in the
**Date 1**box (or click the*Collapse Dialog*button to the right of the box) and select a cell containing the first date. - Click in the
**Date 2**box and select a cell with the second date. - Select the desired unit or combination of units from the
**Difference in**drop-down menu. As you do this, the wizard lets you preview the result in the box and the formula in the cell. - If you are happy with the preview, click the
**Insert formula**button, otherwise try different units.

- Click in the

For example, this is how you can get the **number of days** between two dates in Excel:

Once the formula is inserted in the selected cell, you can copy it to other cells as usual by double-clicking or dragging the fill handle. The result will look similar to this:

To present the results in the most suitable way, a few more additional options are available:

**Exclude years**and/or**exclude months**from calculations.- Show or do not show
**text labels**like*days*,*months*,*weeks*, and*years*. - Show or do not show
**zero units**. - Return the results
**as negative values**if Date 1 (start date) is greater than Date 2 (end date).

As an example, let's get the difference between two dates in years, months, weeks and days, ignoring zero units:

### Benefits of using Date & Time Formula Wizard

Apart from speed and simplicity, the Date & Time Wizard provides a few more advantages:

- Unlike a regular DATEDIF formula, an advanced formula created by the wizard does not care which of the two dates is smaller and which is larger. The difference is always calculated perfectly even if Date 1 (start date) is greater than Date 2 (end date).
- The wizard supports all possible units (days, weeks, months and years) and lets you choose from 11 different combinations of these units.
- The formulas the wizard builds for you are normal Excel formulas, so you are free to edit, copy or move them as usual. You can also share your worksheets with other people, and all formulas will remain in place, even if someone does not have the Ultimate Suite in their Excel.

If you are curious to try the Date & Time Wizard in your worksheets, you are welcome to download 14-day trial version. And if you like the tool and decide to get a license of the Ultimate Suite, be sure to grab the **15% off** coupon code that we provide exclusively to our blog readers: AB14-BlogSpo.

This is how you compute the difference between two dates in various time intervals. Hopefully, the DATEDIF function and other formulas you've learned today will prove useful in your work. Anyway, I thank you for reading and invite to check out other tutorials to working with days and time in Excel.

Hi,

I am using Excel 2010 and am trying to work out a formula to work out the difference between two dates

Could you please help?

Thank you

=DATEDIF(B2,C2+1,"d")

Please try this one. In B2 start date & in c2 end date.

I see you add the +1 in the formula. I was wondering about this. I have accounted for this in the past, but everything shows that the number of actual days is apparently one less. Example: 01-NOV-2017 and 30-NOV-2017, no matter what function you use, the answer comes up 29 days instead of 30.

I usually add the +1 at the end of the formula, but it should come out the same.

It seems like the functions do not take into account the first day as if you really didn't meant to count it.

dateif doesn't exists

Hi Alex,

Dateif doesn't exist, but DateDif does :) However, DATEDIF in an undocumented function, which is why it does not appear in the list of formulas, so you will have to type a whole formula manually.

How to write a single formula for calculating Retirement Date which should be calculated depending following three conditions - If Public Sector Employee then Retirement Age should be 60 yrs, If Private Sector Employee the Retire Age should be 58 yrs and for Pensioners should be 70 yrs

Thanks

The most relevant unit of time measure for me is months between start and ending dates. Excel has a function, DATEDIF, which on surface sounds simple:

=DATEDIF(‘Start Date’,’End Date’,M) will report the number of complete months between dates.

That works 95% of the time but sometimes contracts cross leap years or they don’ start on the 1st day of the month or end on the last day of month.

Here is my solution

=ROUND(IF(TEXT(YEAR('Start Date'),0)&TEXT(MONTH('Start Date'),0)=TEXT(YEAR('End Date'),0)&TEXT(MONTH('End Date'),0),-1,DATEDIF(EOMONTH('Start Date',0)+1,EOMONTH('End Date',-1)+1,"M"))+(DATEDIF('Start Date',EOMONTH('Start Date',0),"D")+1)/DAY(EOMONTH('Start Date',0))+(DATEDIF(EOMONTH('End Date',-1),'End Date',"D"))/DAY(EOMONTH('End Date',0)),2)

I know that it looks wordy but I store it in a most used functions worksheet so I can copy it into my worksheet.

Below is sample of what it answers

Start Date End Date Real Months

1/1/2017 12/31/2017 12.00

1/1/2017 1/2/2017 0.06

I'm trying to do this in excel but it doesn't give me the option for DATEDIF, only DATE or DATEVALUE...so I'm not sure what to do. Do you guys have a different formula that I can use without that function?

Weird because I have the newest version...

The datedif function no longer exists inf Office 2016. As usual, when the imbeciles at Microsoft "improve" a product, they remove useful functions.

Hi Wayne,

DATEDIF still works in Excel 2016. But it is undocumented, meaning you won't find it in the list of functions. To use DATEDIF in your formulas, you need to remember its syntax and type all the arguments manually.

I am using the datedif function to calculate years of service for employment. I have that part down with the exception of employees that had a break in service. How do I add their previous years served before their break in service to their current years of service?

Example:

Current Date of Hire: 9/25/1999 to Present

Current Time in Service: 18Y, 1M

Previous Date of Hire: 5/23/1987

Previous Termination Date:9/20/1991

Previous Time in Service: 4Y, 3M

How to I create a formula to add the current time in service along with the previous time in service?

Hi! Thanks for these instructions - the site/tutorials are great and I've learned a lot! I was wondering if you had any tips for me:

I am trying to display the date, that is x number of days after Jan 1.

I used:

A1 =datedif("01/01/2017","11/27/2017", "d")

to display how many days it has been since the start of the year.

I am now trying to display the date 30 days prior.

I was able to find the day number this year by:

=datedif("1/1/17", A1, "d")- 30

For instance, this equals 300. How do I display the 300th day of the year (i.e. October 27)?

Thanks!

Hi,

How to calculate difference in two dates in days when the date is selected/inserted from calendar through Microsoft Date and Time Picker Control.

This formula is not working =DATEDIF(A2, B2, "d") because it is not considering cell to the cell where date is selected from picker.

Thanks

What about if you use the month of February. If you deduct 28 feb 2018 and 31 Jan 2018 it will be zero month

Hi there. Newbie to Excel, so no expert by any stretch. I'm trying to work out how to do a formula to count days within a month only. I have two columns titled "Start Date" and "Finish Date". For example. Start Date is 22 Jan 18 and Finish Date is 11 Feb 18. Is there a formula to count the number of days (within those two columns) for the month of January 2018 only? It would equal 9 days. I then need another formula, same example as above, to calculate the days that would be returned for February 2018 only, ie. would equal 10 days. The total amount of lines within the speadsheet could be anywhere up to 500 lines. I have found formulas to count the total days, but not exactly for a month only. Hope that makes sense. Thanks.

how to set age limit for ex: 25.3.1978 to 15.4.1983, if age is between 35 to 40, i have to set 35 how to do it

Hi,

Can someone help me to that I want to find the days in between my start date & today date.

I tried

=DATEIF(today(), “3/6/2018” , “d”)

But the result is #NAME?

Thanks!

Hi Mavis,

Please first note that you have a typo in the function name. Besides, if your start date is prior the today's date, you need to change the position of the formula arguments. Thus, the correct formula should look like this:

=DATEDIF("3/6/2018",TODAY(),"d")

Hope this will work for you.

Hi,

This formula =NOW()-A1 does not work for same day calculation:

if today is 18 Mar 2018, the result shows a month!

For example A1 is 18 Mar 2018 07:10:00PM

I want to equal 1 year to date

hi there, can someone help me, i need help in column in where it would say "ready" if its within a year from today's date and the other will say "under construction" if its still over a year from today's date.

I need to find the difference between two dates in weeks and days. Can you help me?

Fawn:

Where start date is in A1 and end date is in B1 enter this in C1 for days

=DATEDIF(A1,B1,"D")

enter this in D1 for whole weeks

=ROUNDDOWN(DATEDIF(A1,B1,"D")/7,0)

How do I calculate the number of days between two dates in two columns?

Helen:

Where the oldest date is in A1 and the newest date is in B1, put this in C1:

=DATEDIF(A1,B1,"D")

21-09-1981 36 Years, 8 Month,17 Days

Date is blank 118 Years, 5 Month,8 Days ( I want to show this colum empty)

118 Years, 5 Month,8 Days

118 Years, 5 Month,8 Days

I issued this formula for date calculation DATEDIF($F5,TODAY(),"y")&" Years, " &DATEDIF($F5,TODAY(),"ym")&" Month,"&DATEDIF($F5,TODAY(),"md")&" Days"

When date cell is empty formula cell show blank please help solve to this problem

Hi

Maybe someone can help me, I need to determine the difference in weeks for example: the difference between week year - week year (10 2018 - 22 2018)= 12

Luis:

You need to enter the date in a format your version of Excel recognizes as a date like 1/1/18 is January 1st 2018 in my version.

If your version supports DATEDIF, then you can enter this formula in the display cell of your choice

=ROUNDDOWN(DATEDIF(A47,D47,"D")/7,0)

So, if A47 holds the date 3-Apr-14 and D47 holds the date 1-Sep-18 this formula will return 230.

Be sure to format the cells as dates.

You can change the A47 and D47 to the cell addresses that suit you.
