The reason why we chose to have Anniversary Pokémon and not
Birthday Pokémon is because we wanted every user to have equal
chances to get one. For example someone who's birthday is one week
after registration gets it quicker than someone who celebrated
their birthday a few days before signing up.
Having an Anniversary Pokémon that everyone gets after exactly one
year is the fairest solution in my opinion :)
