If the player visits a Pokémon Center on their birthday in any of the Generation VI Pokémon games, they will receive a special message wishing them a happy birthday.

In the Japanese versions, the Pokémon Center will additionally play a music box rendition of "Happy Birthday to You", which is replaced by a similar version of the Pokémon Center theme on subsequent visits that day. The international release omits the former song, only playing the latter even on the player's first visit. This is owed to the fact that "Happy Birthday to You" was still nominally under copyright in the United States, not officially falling into the public domain until 2016 after a three-year legal battle (the song was declared de facto public domain in 2015, but the final settlement was not issued until the following year).
