Maybe we could manage to get it directly without makind rounding after.

Like this inside the query : SELECT TIMESTAMPDIFF(YEAR, birthday, CURDATE()) AS age

You are right @PrestaEdit , if we take a very close date the floor does not work either.
There are years with 366 days
I will correct

My test i put 18/07/2022 return 22 years

Hello @okom3pom ,

Thanks for the PR.

Tested on PS 1.7.8.x, 8.0.x, develop.
Tested with multiple dates:

• current year
• date of the day
• date after the current day
• date before the current day
• previous date with ages > 3 figures

Looking good to me.
It is QA ✅
