Characters who have reached their Birthday will send you a mail with their Special Dish and a gift that relates to ascending the character's talents or level.
It is not required to own the specific characters, all players will receive the celebratory mail regardless. However, the mail is only sent on log-in of that specific day and will not be able to be received the day after.
The Traveler's birth date depends on the player's choice in their profile customization and cannot be changed again once set. Once the Traveler celebrates their birthday, the Dev Team, via the mailing system, will send birthday wishes, along with a special gift of one Cake for Traveler, which rewards one Fragile Resin and an unusable version of the cake when used.
On top of this, any characters the player currently has will have their "Birthday" voice line permanently unlocked.
