ROM Hack Pokemon symbols that aren't showing up

Preface - Mods if this is considered a topic that either doesn't belong or should have been merged with my own topic, please let me know and delete it.

Now then. I was wondering if anyone knew exactly how to edit these symbols in the game:

? - Days
? - Months
? - Years

These are the symbols located on the front and back of the trainer card.
I have everything else on the card translated, but these symbols are a bit of an eyesore in my opinion.

Any help or suggestions would be appreciated

I think they are graphics, not text!

Ahhh then that would explain a lot. Think it would be possible to rip them and modify them that way?

They're definitely graphics. The NARC with the trainer card files is /a/0/4/9.

I haven't completed this but it's a list of what each NARC in HG/SS contains, should be useful:
