at the top of your profile page, just below your icon/avatar, you should see a number of different information tabs. click on the tab on the far left, stating your name, age, gender, artist type ect.
below the tab a green box containing some more information should appear. in the top corner of the box click, click the "edit" button. you will then be able to change information about yourself, including your birthday.
its simple once you get the hang of it, but if you can't find the right tabs/buttons just search around a little and they'll be there! ;)
I don't think that works, though :(
