Today, we want to calculate the age basing on the date of birth.
It’s a really simple task. We just want to know one hidden function. It’s called DATEDIF. Excel won’t show its syntax, but it will calculate it properly, if we give it proper arguments. The first argument of this function is the start date, which is our date of birth. The second argument is the TODAY function. The last argument is ‘Y’, as we want to calculate whole years (Fig. 1)
=datedif(A2,TODAY(),“Y”)

And just like that, we have calculated the age basing on the date of birth (Fig. 2)
