declare @birthday datetime, @d datetime

select datediff(yy, @birthday, @d) -
(case when (datepart(m, @birthday) > datepart(m, @d)) or
(datepart(m, @birthday) = datepart(m, @d) And
datepart(d, @birthday) > datepart(d, @d))
then 1
else 0
end) as Age1
-- Just for completion, another way to do the same
select year ( dateadd( dd, datediff ( dd , @birthday , @d ) ,
'1900-01-01 00:00' ) ) - 1900
-- To find out if a year is leap year or not, use
if ( year ( @d ) % 400 = 0 ) Or
( year( @d ) % 4 = 0 And year ( @d ) % 100 <> 0 )
print 'Leap Year - 366 days'
else
print 'Not a leap year - 365.25 days'

I thought a year had 365 days on a regular year. Isn't the .25 for the average including the leap year???

Great stuff -- datediff is a pain in the neck sometimes (while extremely useful). I'm using this to calcualate time till next annual event (even if the 1st time the event happened was 20 years ago). Much thanks for the example.

Great Stuff
One Question - In the second alternative why to use dateadd when this can work
select year ((datediff(dd , '09-13-1975' , getdate()))) - 1900
If any special reason pls do mention.
Thanks
