Happy Birthday Bot

[No longer operational] Often forget when the birthday of your friend is? Never again! Just add me to your chat group and ask your friends to write the command /mybirthday [friend’s birthday date in format dd.mm.yyyy]. When the day comes I’ll send my congratulation to this chat group. I’ll take the birthday person's profile photo, modify it adding some cool things and send it too. Finally, I’ll set this new photo as the chat profile photo! With me it’s impossible to forget about birthdays of your friends!
