But of course =YEAR($J$1)-YEAR(C2) doesn't calculate current age, it
calculates the age attained during that calendar year. For someone born in
December 2000, that formula would give their age as 8, whereas currently
they are 7. DATEDIF(C2,$J$1,"y") might be better, & can be nested in a test
for C2 not being blank as Gord suggested.

I have a formula =YEAR($J$1)-YEAR(C2) calculating age from date of birth.

However some of my entries do not have an entry for date of birth, so
their
'age' ends up as being (for example) 108.

Is there a way of making sure the formula does not calculate these ages?

Thanks
