Since our characters name day is basically just a different way of saying their birthday, feels kinda lack luster that it has no impact at all on your character.

Was thinking that maybe on your characters name day, they could get a name day letter from SE wishing them a good fortune and have a slice of cake attached to it that gives some kind of 24 hour buff. As to what the buff is that'd be up to the devs to decide for balance reasons. Make the cake unique and untradable of course.

Not sure if someone having a slight boost to xp or gil earned or whatever would be chosen for 1 day a year would be too unbalanced.
