Birthday as a mandatory field


On create customer account I would like to have the birthday as a mandatory field.

Quick registration:
Is enabled and marked with a hook.

Looking for the template name for this change, since I believe, I have changed it a long time ago there!

Thanks for your help.

Many regards.

try design/themes/THEME/templates/views/profiles/components/profile_fields.tpl

Do you use the “Age verification” module?
