I was just wondering if Birthday buttons are always available, or are they just available for the "What will you celebrate" year? If they are always available, does it have to be your actual birthday to get one? My DH's actual birthday is January 23rd, but we will be in the parks for the whole day on the 20th, so I would really like to get a birthday button for him, just so he knows how special you feel when about six million people wish you a happy birthday
