What would be the best way to calculate someone's age in years, months, and days in T-SQL (SQL Server 2000)?
The datediff function doesn't handle year boundaries well, plus getting the months and days separate will be a bear. I know I can do it on the client side relatively easily, but I'd like to have it done in my stored procedure.
Here is some T-SQL that gives you the number of years, months, and days since the day specified in @date. It takes into account the fact that DATEDIFF() computes the difference without considering what month or day it is (so the month diff between 8/31 and 9/1 is 1 month) and handles that with a case statement that decrements the result where appropriate.
DECLARE @date datetime, @tmpdate datetime, @years int, @months int, @days int
SELECT @date = '2/29/04'
SELECT @tmpdate = @date
SELECT @years = DATEDIFF(yy, @tmpdate, GETDATE()) - CASE WHEN (MONTH(@date) > MONTH(GETDATE())) OR (MONTH(@date) = MONTH(GETDATE()) AND DAY(@date) > DAY(GETDATE())) THEN 1 ELSE 0 END
SELECT @tmpdate = DATEADD(yy, @years, @tmpdate)
SELECT @months = DATEDIFF(m, @tmpdate, GETDATE()) - CASE WHEN DAY(@date) > DAY(GETDATE()) THEN 1 ELSE 0 END
SELECT @tmpdate = DATEADD(m, @months, @tmpdate)
SELECT @days = DATEDIFF(d, @tmpdate, GETDATE())
SELECT @years, @months, @days
Try this...
SELECT CASE WHEN
(DATEADD(year,DATEDIFF(year, @datestart ,@dateend) , @datestart) > @dateend)
THEN DATEDIFF(year, @datestart ,@dateend) -1
ELSE DATEDIFF(year, @datestart ,@dateend)
END
Basically the "DateDiff( year...", gives you the age the person will turn this year, so i have just add a case statement to say, if they have not had a birthday yet this year, then subtract 1 year, else return the value.
SELECT DATEDIFF(year, @datestart ,@dateend) + CASE WHEN (DATEADD(year,DATEDIFF(year, @datestart ,@dateend) , @datestart) > @dateend) THEN - 1 ELSE 0 END –
Drawplate Simple way to get age as text is as below:
Select cast((DATEDIFF(m, date_of_birth, GETDATE())/12) as varchar) + ' Y & ' +
cast((DATEDIFF(m, date_of_birth, GETDATE())%12) as varchar) + ' M' as Age
Results Format will be:
**63 Y & 2 M**

+ (sign(day(@dob) - day(@now))+1)/2 * (@days_in_birth_month - day(@dob) + day(@now))
-- ( (-1+1)/2*(28 - 29) + (1+1)/2*(29 - 29 + 28))
-- Explain: if the days of now is bigger than the days of birth, then diff the two days
-- else add the days of now and the distance from the date of birth to the end of the birth month
select @years,@months,@days -- 0, 11, 28
The approach of days is different from the accepted answer, the differences shown in the comments below:
dob now years months days
2012-02-29 2013-02-28 0 11 28 --Days will be 30 if calculated by the approach in accepted answer.
2012-02-29 2016-02-28 3 11 28 --Days will be 31 if calculated by the approach in accepted answer, since the day of birth will be changed to 28 from 29 after dateadd by years.
2012-02-29 2016-03-31 4 1 2
2012-01-30 2016-02-29 4 0 30
2012-01-30 2016-03-01 4 1 2 --Days will be 1 if calculated by the approach in accepted answer, since the day of birth will be changed to 30 from 29 after dateadd by years.
2011-12-30 2016-02-29 4 1 30
set @days = CASE WHEN day(@now) >= day(@dob) THEN day(@now) - day(@dob)
ELSE @days_in_birth_month - day(@dob) + day(@now) END
If you want the age of years and months only, it could be simpler
set @years = ( @now_i/100 - @dob_i/100)/100
set @months =(12 + month(@now) - month(@dob))%12
select @years,@months -- 1, 0

It works pretty well.
I've seen the question several times with results outputting Years, Month, Days but never a numeric / decimal result. (At least not one that doesn't round incorrectly). I welcome feedback on this function. Might not still need a little adjusting.
-- Input to the function is two dates. -- Output is the numeric number of years between the two dates in Decimal(7,4) format. -- Output is always always a possitive number.
-- Logic is based on three steps. -- 1) Is the difference less than 1 year (0.5000, 0.3333, 0.6667, ect.) -- 2) Is the difference exactly a whole number of years (1,2,3, ect.)

Quite Old question, but I want to share what I have done to calculate age
Declare @BirthDate As DateTime
Set @BirthDate = '1994-11-02'
SELECT DATEDIFF(YEAR,@BirthDate,GETDATE()) - (CASE
WHEN MONTH(@BirthDate)> MONTH(GETDATE()) THEN 1
WHEN MONTH(@BirthDate)= MONTH(GETDATE()) AND DAY(@BirthDate) > DAY(GETDATE()) THEN 1
Else 0 END)
Are you trying to calculate the total days/months/years of an age? do you have a starting date? Or are you trying to dissect it (ex: 24 years, 1 month, 29 days)?
If you have a start date that you're working with, datediff will output the total days/months/years with the following commands:
Select DateDiff(d,'1984-07-12','2008-09-11')
Select DateDiff(m,'1984-07-12','2008-09-11')
Select DateDiff(yyyy,'1984-07-12','2008-09-11')
with the respective outputs being (8827/290/24).
Now, if you wanted to do the dissection method, you'd have to subtract the number of years in days (days - 365*years), and then do further math on that to get the months, etc.
DateTime values in T-SQL are stored as floats. You can just subtract the dates from each other and you now have a new date that is the timespan between them.
declare @birthdate datetime
set @birthdate = '6/15/1974'
--age in years - short version
print year(getdate() - @birthdate) - year(0)
--age in years - visualization
declare @mindate datetime
declare @span datetime
set @mindate = 0
set @span = getdate() - @birthdate
print @mindate
print @birthdate
print getdate()
print @span
--substract minyear from spanyear to get age in years
print year(@span) - year(@mindate)
print month(@span)
print day(@span)
month(@span) and day(@span), respectively, which would be consistent with subtracting year(@span)). This answer is the same as Leonardo's, which was also re-posted by simon831 in the form of a function. It's unreliable, anyway. Accuracy/error seems to depend on the number of days in the current month as well as on that in the month of @birthdate. Today is 4/5/2012, I tried your suggestion for set @birthdate = '4/5/1974' and got 38 0 1, even though it should be 38 0 0. –
Melli Here is SQL code that gives you the number of years, months, and days since the sysdate. Enter value for input_birth_date this format(dd_mon_yy). note: input same value(birth date) for years, months & days such as 01-mar-85

For the ones that want to create a calculated column in a table to store the age:

THEN DATEPART(YEAR, GETDATE()) - DATEPART(YEAR, DateOfBirth)
ELSE DATEPART(YEAR, GETDATE()) - DATEPART(YEAR, DateOfBirth) -1 END
Here is how I calculate the age given a birth date and the current date.
select case
when cast(getdate() as date) = cast(dateadd(year, (datediff(year, '1996-09-09', getdate())), '1996-09-09') as date)
then dateDiff(yyyy,'1996-09-09',dateadd(year, 0, getdate()))
else dateDiff(yyyy,'1996-09-09',dateadd(year, -1, getdate()))
end as MemberAge
go
There is an easy way, based on the hours between the two days BUT with the end date truncated.
SELECT CAST(DATEDIFF(hour,Birthdate,CAST(GETDATE() as Date))/8766.0 as INT) AS Age FROM <YourTable>
This one has proven to be extremely accurate and reliable. If it weren't for the inner CAST on the GETDATE() it might flip the birthday a few hours before midnight but, with the CAST, it is dead on with the age changing over at exactly midnight.
There is another method for calculate age is
See below table
FirstName LastName DOB
sai krishnan 1991-11-04
Harish S A 1998-10-11
For finding age,you can calculate through month
Select datediff(MONTH,DOB,getdate())/12 as dates from [Organization].[Employee]
Result will be
firstname dates
sai 27
Harish 20
I have created a function calculateAge that takes parameter dateOfBirth from outside and then it calculates the age in years, months and days and finally it returns in string format.
CREATE FUNCTION calculateAge(dateOfBirth datetime) RETURNS varchar(40)
BEGIN
set @currentdatetime = CURRENT_TIMESTAMP;
set @years = TIMESTAMPDIFF(YEAR,dateOfBirth,@currentdatetime);
set @months = TIMESTAMPDIFF(MONTH,dateOfBirth,@currentdatetime) - @years*12 ;
set @dayOfBirth = EXTRACT(DAY FROM dateOfBirth);
set @today = EXTRACT(DAY FROM @currentdatetime);
set @days = 0;
if (@today > @dayOfBirth) then
set @days = @today - @dayOfBirth;
else
set @decreaseMonth = DATE_SUB(@currentdatetime, INTERVAL 1 MONTH);
set @days = DATEDIFF(dateOfBirth, @decreaseMonth);
end if;
RETURN concat(concat( concat(@years , "years\n") , concat(@months , "months\n")), concat(@days , "days"));
END
Plenty of solutions have been given already, but I beleive this one to be both easy to understand and reliable, as it will handle leap years as well :
case when datepart(dayofyear, @birth) <= datepart(dayofyear, getdate())
then datepart(year, getdate()) - datepart(year, @birth)
else datepart(year, getdate()) - datepart(year, @birth) - 1
end
The idea is to simply compute the difference in years between the two years (birth and now), and substract 1 if the anniversary has not been reached for the current year.
