How do I calculate relative years + days between two dates in excel? I want to know the number of years and any additional days (outside of the full years). Dividing the total days by 365 doesn't work because of leap years. For example:
Cell A1 = '1/31/2015'
Cell B1 = '2/1/2025'
Cell C1 = '2/11/2025'
=(B1-A1)/365 # 10.0109 = 10 years + 4 days, looking for 10 years + 0 days
=(C1-A1)/365 # 10.0383 = 10 years + 14 days, looking for 10 years + 10 days
Is there an easy way to calculate this?
Note - this question is not a duplicate of How to find the difference between dates in VBA -- which is a question about calculating the difference between dates. This question is asking how to calculate the difference of both years and days, such that the difference in days is for the final year only, and are not incorrectly including leap year days for previous years.
You can use the documented function DATEDIF
=DATEDIF(startdate,enddate,"Y")
This will give you the difference in whole years
“Y” Returns the period difference as complete years.
“M” Returns the period difference as complete months.
“D” Returns the number of days in the period.
“MD” Returns the difference between the days in ‘Start_Date’ and ‘End_Date’. Here the months and years of the dates are ignored.
“YM” Returns the difference between the months in ‘Start_Date’ and ‘End_Date’. Here the days and years of the dates are ignored
“YD” Returns the difference between the days of ‘Start_Date’ and ‘End_Date’. Here the years of the dates are ignored.
Excel Solution :
=DATEDIF(A1,A2,"y") & " years, " & DATEDIF(A1,A2,"ym") & " months, " & DATEDIF(A1,A2,"md") & " days"

how to get different between two dates: column1 "joining date" column2 "leaving date", in sharepoint calculated column as "total experience of an employee"?
The desired output I'm searching is in this format for example: "2 days 2 months 2 years".
this formula should give you the answers that you are after
= DATEDIF([Date 1],[Date 2],"MD")&" Days "& DATEDIF([Date 1],[Date 2],"YM") &" Months "& DATEDIF([Date 1],[Date 2],"Y") &" Years"
Steps:
Create a calculated column of type Single Line of text
Use the formula above.
Explanation:
Formula goes as
DATEDIF(Start_date,End_date,"Interval")
Where interval can be:
Y Calculate the number of complete years
M Calculate the number of complete months
D Calculate the number of days
YM Calculate the number of months excluding years
MD Calculate the number of days excluding years and months
YD Calculate the number of days excluding years
For 2 dates like Date 1 (31/01/2020) and Date 2 (14/05/2020), the results will be:
14 Days 3 Months 0 Years
I am attempting to determine the number of months and days between two dates to determine an group of individuals length of service, so that I can ascertain if they are within 2 ranges 0-6 mths and 6-23mths, I have the following but I'm missing something, as it can't seem to handle 10 months or over, its returning 0-6 mths for those. I will also need to add a third range (0-6, 6-12 & 12-23) for a future project but am having difficulties with this one also?
=IF(DATEDIF(F155,G155,"ym")&" months " &DATEDIF(F155,G155,"md")&" days">="6 months 0 days", "6 - 23 Months","0 - 6 Months")
The problem is that you are comparing 2 strings that do not have the same format:
For example for dates 1/1/2019 with 11/1/2019 you are comparing "10 months 0 days" vs "6 months 0 days" (a 2 digits number vs a 1 digit number in the begining strings). You have to make them the same format to be able to compare:
=IF(DATEDIF(F155,G155,"ym")&" months " &RIGHT("0"&DATEDIF(F155,G155,"md"),2)&" days">="06 months 00 days", "6 - 23 Months","0 - 6 Months")
This way you would be comparing "10 months 00 days" vs "06 months 00 days" and since now they have the same format it will work.
It might be simpler to use VLOOKUP.
And, if you expect to get a range of 12-23 months, why are you using the "ym" argument for DATEDIF? That can never return a value more than 12.
I suggest something like:
=VLOOKUP(DATEDIF(F155,G155,"m"),{0,"0 to 6 months";6,"6 to 12 months";12,"12 to 23 months";24,"undefined"},2)
Also, suggest you read about the different arguments for DATEDIF; and you should probably read HELP for VLOOKUP also.
If you need to extend the table more, consider putting it into an Excel table instead of an array constant.
I’m trying to compare a measure as of today through the same day and month for the prior 4 years (e.g. through June 6 of 2016, 2015, 2014, etc.).
For each year, I decided to count the number of days since the beginning of the year, and sum my values through that number of days for each year.
To identify whether a date should be included in the year to date comparison, I used the formula where my date is in cell A1:
=IF((A1-DATE(YEAR(A1),1,1)+1)<=(TODAY()-DATE(YEAR(TODAY()),1,1)+1),1,0)
I’m looking for a way around the issue of the extra day added to leap years. In other words, after February 28th, the day count will always be off by one in a leap year, and trying to use Februrary 29th in a non-leap year will return an error.
I’d like to adjust this formula, but I’m open to using a different function & formula if it gets me the right results.
you can check any information about February, 29th. If an error occurs, you know its no leap year. Catch that error with =IFERROR(;).
Assuming a table structure like this:
A:Date | B:Value
----------------------
01/01/2016 | 0
01/01/2015 | 1
01/01/2014 | 2
01/01/2013 | 3
01/01/2012 | 4
Formula
To - for example - calculate the average of the previous four (excluding the current) years on January 1st (today is 01/01/2016):
=SUMPRODUCT(
(MONTH(A:A)=MONTH(compare))*
(DAY(A:A)=DAY(compare))*
(YEAR(A:A)>YEAR(compare)-5)*
(YEAR(A:A)<YEAR(compare))*
(B:B)
) / (
SUMPRODUCT(
(MONTH(A:A)=MONTH(compare))*
(DAY(A:A)=DAY(compare))*
(YEAR(A:A)>YEAR(compare)-5)*
(YEAR(A:A)<YEAR(compare))*
1
)
)
Result
For the above example, the result is 2.5
Explanation
To select only those rows representing the same month and day:
(MONTH(A:A)=MONTH(compare))*(DAY(A:A)=DAY(compare))
To select only those values from the previous 4 years (excluding the current):
(YEAR(A:A)>YEAR(compare)-5)*(YEAR(A:A)<YEAR(compare))*
The actual values we are interested in:
(B:B)
Divide by 4 for the average over the last four years. This assumes there is no missing data which might be an issue. You could use another SUMPRODUCT (replace B:B with 1) to count the number of resulting rows and divide by that number to handles this case. This seems to be rather slow, but it works.
Note
For performance reason you should not use A:A (a full column) in the formula, just use the actual range you need, which will likely be much faster.

How to calculate total number of months and year in between two dates in groovy
date1 =2012 nov 1
date2 =2013 feb 1
required output is year = 0 and month =3.
Any answer is helpful
I think this should do:
monthBetween = (start[Calendar.MONTH] - end[Calendar.MONTH]) + 1
yearsBetween = start[Calendar.YEAR] - end[Calendar.YEAR]
months = monthBetween + (yearsBetween * 12)
Taken from Calculate difference in months between two dates with Groovy
I am needing to calculate the number of years between two fields;
Field A
Start Date (dd/mm/yyyy)
Field B
End Date (dd/mm/yyyy)
Field C
Calc formula display difference between Field A and B in years and months i.e 5.2
Thanks all.
Assuming you are asking about Calculated Columns then you need the DATEDIF function
Also I am assuming that the 5.2 is 5 years and 2 months - not 5 years and .2 of a year - be a bit more specific in your question and you will get better answers.
So
= DATEDIF([Start Date],[End Date],"Y")
& " years and " &
DATEDIF([Start Date],[End Date],"YM")
& " months "
