You can find the feel functions and expressions here: What is FEEL? | Camunda Platform 8 Docs

thank you for the message. If I create this as a Decision Table and then try to simulate this in the DMN Simulator, I get the following error message:
If I put in a hardcoded date instead of today(), then it works. Have I made a mistake in the DMN file? Attached is the file.
AgeDMN.dmn (2.9 KB)
You could simplify the FEEL expression a bit by using the

years and months duration(date(birthday), today()).years
It is an example from Temporal Samples | FEEL-Scala
