After James died, Sirius stopped celebrating his birthday since it’s so close to October 31st.
But, every year while he was in Azkaban, on his birthday, he would wish for James back just in case. He would never be there after Sirius makes his wish though.
Birthday wishes died the moment James did.
He only ever got to celebrate 9 birthdays: 1971-1979. Sirius may have been alive, but he died the same night James did.
