Developer 1: What's the best naming convention to use for these PDF account statements, keeping in mind that users will have multiple accounts and probably want to sort them by date?

Developer 1: Are you thinking BANK NAME - DAY OF MONTH - THREE FIRST LETTERS OF MONTH NAME - YEAR?!
Developer 2: YESSSSS.
