If you call the anniversary of your birth your anniversary you will not be understood. There are too many things that an anniversary could be an anniversary of. If it doesn't bother you that people don't understand you when you refer to the anniversary of your birth as your anniversary, fine. If you wish to be understood you should at least refer to it as the anniversary of your birth. You could also call it your birthday and people will understand you. To insist on obsolete usages at the expense of understanding is just nice.
