Date Helper Expression for First/Last Day of Current Month in AJO Template

Hi everyone,

I’m trying to generate dynamic dates inside an AJO Email/HTML template, specifically:

“Promotion valid from "01/{{current_month}}/{{current_year}}" to {{last day of current month}}/{{current_month}}/{{current_year}}.”

What is the correct PQL expression to generate the first day of the current month in AJO?

Thanks.
