I do name Notes with dates, old habit and I use the form YY.MM.DD.
One thing I noticed is that Agenda evaluates the title and when I choose to assign a date to the note it jumps to what it thinks I want.
Being helpful and smart, which we like.
Except my non-standard date format trips it up. So for today 19.06.17 (my version) it jumps to 19 June 2017.
