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. 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 7, 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 8 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).

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. 1-12 and months in the 2nd column Jan-Dec) 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. 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. 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. Hello, I have a column in my spreadsheet for birth date, that is formatted as DD-Mon-YY (ie 11-Feb-03 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 11-Mar-15 as today's date. Also note: The regional settings in my control panel list short date as dd-MMM-yy, so I don't think this would be the problem. 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. To make it read in that format you'll need to go to the 'Custom' option under format and enter:$-809dd-mmm-yy;@ 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 This will give you '12 Years, 1 Months, 1 Days' Thanks, Thom.

$begingroup$ Doesn't 'ideally exposing only a single member' imply that everything can be declared as a delegate instead of as an interface? For example, instead of IUserInputProvider inputProvider, Func GetUserInput (input parameter is the prompt and return value is the user input)? And instead of IUserInputValidator confirmationValidator, Func Validate? With interfaces, you need to declare the interface, declare the method in the interface, declare a separate class which implements the interfaces, construct an instance of the class.
