How to calculate age by date of birth

[Paknanarn23]

I want to calculate age The calculation is divided into how many years, how many months, and how many days.

I have inserted this code. But the value that comes out is incorrect. There are 12 months in a month. But calculated for more than 12 months and calculated for more than 30 days. What should I do?

I think you could use age() or interval() to get the wanted information.
