For some users, the Edit Age feature is not displayed. We are changing the way you enter your age on Profiles so that when you enter your birth date, your age is calculated for you. We are also introducing a birthday reminders feature that allows your friends to know when your birthday is coming up and vice versa, if you choose to share your birthday.
Why?
Recently, you may have received a notice upon accessing your account where we asked you to update your Account Information. Once this updated Account Information is provided, users are allowed to edit the Age that appears on their Profile in 30 days. If you would like to edit your Age, you will need to update your Account Information.
Your Security
The security of your data is important to us. In order for us to make sure Yahoo!'s can still recover their accounts, we are keeping birth date as an account recovery option for 30 days after you change this. To keep your data protected, we have to temporarily omit the ability to edit this information on profiles for 30 days. You will be able to edit your birthday and therefore age in 30 days from the Edit Basics page.
