수식을 사용하여 생년월일로 변환
방법 A : 뺄셈을 통해 생년월일로 변환
보통 우리는 주어진 생일을 빼고 현재 날짜를 가진 누군가의 나이를 알아 낸다. Excel에서도 마찬가지입니다.
1 단계 : 셀 B2016의 4 / 7 / 2과 같이 빈 셀에 현재 날짜를 입력하십시오.
2 단계 : 다른 빈 셀 (셀 C2)에 공식 = INT ((B2A2) / 365), 그리고 엔터 버튼 키.
방법 B : DATEDIF 함수를 사용하여 생년월일 변환
어떤 사람들은 DATEDIF 함수를 적용하여 나이를 계산하기를 원합니다. 수식 입력 = DATEDIF (A2, NOW (), "y") 공백 셀에서를 누르면 즉시 나이를 계산합니다. 엔터 버튼 키.
방법 C : ROUNDDOWN 함수를 사용하여 생년월일로 변환
생년월일로 변환하는 또 다른 기능은 다음과 같습니다. = 라운드 다운 (YEARFRAC (A2, 오늘 (), 1), 0)27와 같은 표준 연령을 알아낼 것입니다.
방법 D : DATEDIF 함수로 정확한 연령으로 변환
때로는 정확한 연령이 필요하며 생년월일부터 현재 날짜까지 몇 년, 몇 개월, 며칠인지 알고 싶어 할 수 있습니다. 다음 수식을 통해 파악할 수 있습니다.
& DATEDIF (A2, TODAY (), "MD") & DATEDIF (A2, TODAY (), "Y") & "연도"& DATEDIF (A2, 오늘 (), "YM") & "일"

To post as a guest, your comment is unpublished.Thank you Catherine,
for the wholehearted appreciation of my solution! 
To post as a guest, your comment is unpublished.I have used the following to calculate the age of children in my class.
=DATEDIF(B4,TODAY(),"Y")&"."&DATEDIF(B4,TODAY(),"YM")
with B4 being their date of birth. It produces the correct answer (eg) 9.11
They take tests 3 months later so I need in another cell to calculate '+3' months. But each time I do this I get 9.14 when I need it to say 10.2
Can anyone help.
Thanks
To post as a guest, your comment is unpublished.

To post as a guest, your comment is unpublished.Unclear my post went through or not, in response to Catherine's query.
Repeat my formula which finds the difference between cell B4 contents and a date TODAY() advanced by 3 months:
=DATEDIF(B4,DATE(YEAR(TODAY()),MONTH(TODAY())+3,DAY(TODAY())),"Y")&"."&DATEDIF(B4,DATE(YEAR(TODAY()),MONTH(TODAY())+3,DAY(TODAY())),"YM") 
To post as a guest, your comment is unpublished.The DATEDIF formula used to give the Years and Months in a YY.MM format is understandable. However, each of the 2 components of this formula is a separate number, integer. So, adding 3 to the MM part will only give 14 if it is 11 before the addition. The formula does not know you are looking to set it up as a MONTH.
So, if you get the DATEDIF between B4, and a date which is a valid date but 3 months after TODAY(), try the following formula, works for me and gave 10.2:
=DATEDIF(B4,DATE(YEAR(TODAY()),MONTH(TODAY())+3,DAY(TODAY())),"Y")&"."&DATEDIF(B4,DATE(YEAR(TODAY()),MONTH(TODAY())+3,DAY(TODAY())),"YM")
Please confirm it worked for you.

To post as a guest, your comment is unpublished.One should be careful using Method C, with the YEARFRAC() function, because of rounding error in computations involving leap years. You will calculate the incorrect age for people born in a leap year.
Example:
John Smith was born on 6/5/1932. 1932 is a leap year. Compute John Smith's age on 6/5/2002. We would say John Smith is 70 years old on his 70th birthday, 6/5/2002. However, because YEARFRAC(DATE(1932,6,5),DATE(2002,6,5), 1) computes to 69.99795627, adding ROUNDDOWN computes to 69. In fact, John is 70. I'm not sure if this is the best solution, but I've added a precise day to the computation, which I assume shouldn't affect other calculations because it is shorter than the formula assumes a day to be.
(1/365.2422) is a precise day when accounting for leap years
My adjusted YEARFRAC is:
YEARFRAC(DATE(1932,6,5),DATE(2002,6,5), 1)+(1/365.2422) which computes to 70.00069418 and when combined with ROUNDDOWN, gives 70.
Putting it all together according to the references in the article:
=ROUNDDOWN(YEARFRAC(A2, TODAY(), 1)+(1/365.2422), 0)

To post as a guest, your comment is unpublished.Responding to Beloved 20160304:20160304 in my yahoo mail box.Somehow, I thought they were not directed at me as I don't seem to have given details with commas, spaces, etc. I had only suggested the use of YEARFRAC() instead of DATEDIF function which i wasn't getting on my Excel. A clarification is welcome.

To post as a guest, your comment is unpublished.Your teachings COULD be helpful but they are DEFINITELY NOT! Not because they are wrong per se but simply because 1. why do you use comma's (,) when Excel only accepts semicolons (;) really beats me? 2. why do you put spaces in your examples when Excel NEVER accepts spaces?? Your work could be helpful but it confuses people instead. So, a perfectly good answer fails to produce the desired result practically on Excel because of YOUR carelessness. You spoil your own good work!...

To post as a guest, your comment is unpublished.It is amazing to understand and very very useful.

To post as a guest, your comment is unpublished.I couldn't find DATEDIF() in my Excel but YEARFRAC() did it. Hope it is reliable, any comment anyone?

To post as a guest, your comment is unpublished.In my Excel, I could not get the DATEDIF() function for whatever reason. Yet, I got a YEARFRAC() function which seems to do the same. Hope it is reliable.
Any comment anyone?

02/02/1966
second february nineteen sixty six
To post as a guest, your comment is unpublished.I have a feeling date functions may do this in later versions of Excel i.e. =month() etc. If not, you'll need to create a table with the number in the first column i.e. 112 and months in the 2nd column JanDec) then use vlookups so that the function can convert the numbers into the correct text. A lot of fun to be had there as I once wrote a sheet that did this very thing, there was further issues involved in using the correct affix i.e. nd rd st or th. Again, lookup tables did that and I was able to shorten the funtions calculations by using if statements instead but that was very fiddly and half the time I found myself trying to use PHP which would do the job in no time! Have a look around online as someone's likely done some VBA that'll do the trick or KUTools probably have something.


To post as a guest, your comment is unpublished.I have about 100 cells with the calculated age as you done.
Is there any easy way to make groupings on all that are the age of 10 etc.
I have automated the document as we will have more people in all the time so I need automated groupings as well.
Any suggestions?

To post as a guest, your comment is unpublished.Hello
Retirement age is 60 years and last date of each month and the formula works, but in our case if an employee's date of birth falls on 1st of any month then he/she will retire on the previous months last date. (eg. employee 1 DOB is 03/01/1960 then output needed is 28022020 and employee 2 DOB is 03/02/1960 then 31032020) 
To post as a guest, your comment is unpublished.Brilliant tips!
Really worked well! If you want the age to display as a single number on Method B  just format the cell to 'Number' with no decimal points  it works!! Hurrah!! 
To post as a guest, your comment is unpublished.Literally none of these worked. When I subtract, it just gives me another date like 03/03/1953

To post as a guest, your comment is unpublished.Channing,
Can you provide cell references and what data is entered in them along with your formula and that cell reference?
First thought is you should format your result as a number instead of Date. That might be your issue.


To post as a guest, your comment is unpublished.Another question in regards to age. How can I get the age in cell B2 [age?] when I have in Cell A2 [26/06/1966] and in Cell B1 [2013] just the year. Thanks.

To post as a guest, your comment is unpublished.Are you just trying to get the age they will be in the year of B1? If so, then just do B2 =(B1(YEAR(A2)))
If that's not what you are looking for, can you explain what it is you need in more detail?

To post as a guest, your comment is unpublished.Here is one i have that accounts for leap days (well it excludes them pretty much)
=IF((DATEDIF((DATE((YEAR(C3)+(DATEDIF(C3,C2,"y"))),MONTH(C3),DAY(C3))),C2,"d"))=365,(DATEDIF(C3,C2,"y"))+((DATEDIF((DATE((YEAR(C3)+(DATEDIF(C3,C2,"y"))),(MONTH(C3)),(DAY(C3)))),C2,"d")1)/365),(DATEDIF(C3,C2,"y"))+((DATEDIF((DATE((YEAR(C3)+(DATEDIF(C3,C2,"y"))),(MONTH(C3)),(DAY(C3)))),C2,"d"))/365))
C2 = Current Date  could use TODAY()
C3 = DOB 
To post as a guest, your comment is unpublished.Not sure if this was covered, but a lot of people right these and don't consider leap years when looking at the difference in days. Here is one I wrote that considers leap year rules (even for the 100 & 400 year rules)....
=IF((DATEDIF((DATE((YEAR(A2)+(DATEDIF(A2,A1,"y"))),MONTH(A2),DAY(A2))),A1,"d"))=365,(DATEDIF(A2,A1,"y"))+((DATEDIF((DATE((YEAR(A2)+(DATEDIF(A2,A1,"y"))),(MONTH(A2)),(DAY(A2)))),A1,"d")1)/365),(DATEDIF(A2,A1,"y"))+((DATEDIF((DATE((YEAR(A2)+(DATEDIF(A2,A1,"y"))),(MONTH(A2)),(DAY(A2)))),A1,"d"))/365))
where A2 is the date of birth, and A1 is the current date (which could be replaced with TODAY() also.
Please let me know if there are any flaws in this or simpliar ways to calculate it.
To post as a guest, your comment is unpublished.Excellent function, Steve. I believe datedif also does consider leap years :) yours looks very similar to something I wrote a couple of years ago add the client wanted to account for leap years and didn't trust datedif

To post as a guest, your comment is unpublished.If I recall correctly, but datedif wasn't the issue regarding leap years. Once you get the number of days difference and you need to identify a specific date at which they will turn an age is when you need to factor in leap days. The second formula I wrote below does account for those days. If you don't consider that in the formula when you forecast you will be off by a few days.



To post as a guest, your comment is unpublished.Method D is exactly what I've been looking for, minus the day portion (easily removed). I've created an inventory of PCs for my company, and am using this to calculate hardware age based on purchase date. My question is this  is there a way to take this formula and make it so that I can essentially click a button to have it applied to a cell, and then just be able to then select the cell I want it to do the calculation on? Otherwise, I'm looking at having to copy/paste the formula to several hundred cells, and then go and manually change the target cell in each one.
Thanks. 
To post as a guest, your comment is unpublished.Hello,
I have added the formula for age that works well. I was able to continue the formula down the entire column which is what I needed. The issue is that a computed "age" appears in each cell despite the fact that I have not filled in a birthdate. ie: everything below the correct calculations in the column reads 115 years as a default. Is there a way to make the age cell blank until a value is placed in the birthdate cell so as not to see ongoing "115's?" Thanks in advance~ 
To post as a guest, your comment is unpublished.

To post as a guest, your comment is unpublished.I like the "Method B" format when figuring out the age. I'm wondering if there is a way to have the years old and just the months old if younger than 2 using that format. Thanks!

To post as a guest, your comment is unpublished.Hello, I have a column in my spreadsheet for birth date, that is formatted as DDMonYY (ie 11Feb03 for my son that was born on February 11, 2003). I used the =DATEDIF function referenced above and it is returning 115 Years, 2 Months, 11 Days. What is wrong and how do I correct it? Thanks for your help.
=DATEDIF(E13,TODAY(),"Y") & " Years, " & DATEDIF(E13,TODAY(),"YM") & " Months, " & DATEDIF(E13,TODAY(),"MD") & " Days"
Note: When I type =today() in a cell it is correctly listing 11Mar15 as today's date.
Also note: The regional settings in my control panel list short date as ddMMMyy, so I don't think this would be the problem.
To post as a guest, your comment is unpublished.Hi Krista,
That would be the length of time since Excel's callander started :P
You're getting that because the cell you're referencing is blank  is you r son's DOB in Cell E13? Because that's the Cell it's calculating from.
Possible fixes:
 Your function contains errors, please see the corrected one below:
=DATEDIF(E13,TODAY(),"Y") & " Years, " & DATEDIF(E13,TODAY(),"YM") & " Months, " & DATEDIF(E13,TODAY(),"MD") & " Days"
 You need to use the format option to format it correctly as a date. i.e. to make it read in that format you'll need to go to the 'Custom' option under format and enter:[$809]ddmmmyy;@ Under 'Type'
 If you're just typing it in like that, it probably won't read it as a date, you need to enter it as 11/02/2003
This will give you "12 Years, 1 Months, 1 Days"
Thanks,
Thom
To post as a guest, your comment is unpublished.Oops. LOL I had drafted this long note to you telling you it was still not working, when I noticed you were right...cell E13 was empty. My son's DOB is in cell E15. Oops. LOL Thanks for your kind help. It's working now. :) Have a great day!!



To post as a guest, your comment is unpublished.Hi,
How do I convert fx 25102002 into a date and than age?
To post as a guest, your comment is unpublished.Hi Tanja,
I'm assuming that would be the 25th October 2002? Is the FX part of the box? If so, I'd start with =right(A1,8) which would give you the last eight digits from cell A1, so if Cell A1 contained "fx 25102002" it would simply return "25102002". Now to convert that 8 digit string into a palatable date, I'd use the =date() function. I've done one for you, you just need to switch the A1 with the cell that contains your function =DATE(RIGHT(A1,4),RIGHT(LEFT(A1,4),2),LEFT(A1,2))
Thanks, Thom
