I found this topic that explains the process for getting the birthday attribute from the current file and calculating age - works really well for the current file.
What I’m look to do is to reference the birthday attribute from a different file so that I can add important ones to my Dashboard when I first open Obsidian.
But I cannot figure out how to modify the =date(today) - this.birthday so that it is pulling the birthday from a file in my CRM folder (example CRM/Daughter Name).
I found some documentation mentioning dv.page but have tried so many different versions of it and just cannot get it to work.
