How to achieve daily notes attr?

[imalightbulb]

Hey guys, I'm new to trilium and quite confused on this part.
I've added a #calendarRoot attr in the Journal > 2021 file but still not sure what should I do if I want to achieve the weekDay2 thing and set up my daily notes. Also does it mean it will recognize files that have the pattern {no}: {Day in 3 words} as my daily journal file after I set it?

Thanks! :)
