Your birthday and Google+

When you sign up for Google+, we’ll ask you to provide your birthday so that we can provide you with features like age-appropriate settings when you use Google services and personalized content. If you already have a birthday associated with your Google account, you won't be prompted to enter your birthday. By default, your birthday (day and month only) will be visible to people in your circles. You can always edit who can see it on your profile.

1. Open Google+. Place your cursor in the top left corner for the Google+ main menu. Click Profile.
2. Click About at the top.
3. Under the Basic Information section, click Edit.
4. In the Birthday section, enter your birth month, day, and year. You can adjust who can see it on your profile using the dropdown menu to the right.
