Use the Clock component in the Designer's Sensors drawer.

It has many important blocks, including

Now(),

Milliseconds from 1970,

and conversion and formatting and duration functions.

This is not as easy as it sounds. You can calculate a duration expressed as a number of milliseconds, but to calculate the number of your in it is not trivial, because there are leap years and such. So, this is something that would work: 

Calculate the duration between now and birth date. That will be a negative number.

Kepp adding a year using Clock1.AddYears, until the duration becomes positive.

Subtract 1 and you have your age.

If you try to calculate an age > 100 you will get 99 and when you take a date in the future as birth date, you will get -1, if you specify an invalid date, you will get an error message. For your enjoyment, I added an .aia to try out.

Cheers, Ghica.
