can i change my date of birth

Hello there! Can you clarify if you mean the date of birth for your game's character or your account's registration information?

I see. Depending on the game, some allow equipment or skills that can change your character's age. However, the 'date of birth' as an exact concept may not be changeable. What game are we talking about here?

Oh, I see. 'Heroes of the Realm' does not currently have a feature that allows you to change the birthdate once it is set. It might be introduced in future updates, but as of now, it's a fixed detail. You would need to start a new character to have a different date of birth.
