Scroll down to "Contact And Basic Info" on the left menu, then over to "Basic Information" and click the edit button to the far right of your birth date and/or birth year. You may modify the birth date here, or set it to "Your Friends" or "Me Only" to hide it. Click save at the bottom of the page to publish your changes.
At the upper right of Facebook, click your profile photo. Scroll down to your birth date and click the right arrow. Change your birthdate using the dropdown menus, and determine who may view it using the audience selection. Your new birthdate will be displayed on your profile.
UPDATE 1/12/14: On your personal timeline, select Update Info and then Edit Personal Info. Change the audience to ONLY ME (the lock symbol) next to Birthday and Year, and leave the month and date as Friends if you choose. Update my phone info and email address if needed.
Your birthday is known around the world after all! But why expose it on Facebook if you don't have to? There are several ways to hide your birth year and age on Facebook. Below are the easiest methods that require no technical knowledge or software programs.
1. HIDE YOUR AGE ON FACEBOOK
This method doesn't change your actual age but hides it from public view. If you want to show your friends that you're old enough to drink in some countries, for example, you can do this easily without actually changing your age.
2. CHANGE YOUR REPUTATION LABEL
Your reputation label is what shows up under your name in the Reviews section of your profile. It's usually based on how many people like, dislike, or comment on you. You can change your reputation label by visiting My Reputation and clicking the "Change Label" link.
Information Regarding Birth Facebook shows your birth date and age on your profile page by default, allowing others to view this information. If you do not want your age or birth date shown, go to your profile settings and click the "Edit Profile" option at the top of the page. Here you can see I have selected not to display my age.
If you share details about your personal life on Facebook, such as your birthday, age may be inferred from other information that you have shared online previously. For example, if you have a high school or college alumni website, they may use this information to inform future birthday cards from them. In addition, birth dates are often used to determine what type of content is displayed in ad campaigns for products that I might be interested in. For example, an ad campaign for cars might only show up when someone is looking for an older model instead of something new.
Facebook also includes an estimate of your age in its calculations of how old you appear to others. If you look at my profile, it says that I seem like I'm around 34 years old. This is because I've given it some previous information about my birth date and now it's using that to calculate my age more accurately. If I didn't give my birth date, it would say I was around 27 years old.
1st, sign in to your Facebook account. 2-To view your timeline page, click on your name. 3-Click the About button. Hover your cursor over your birthdate, and then click the Edit your contact and basic information option that appears. 4-Select the Remove date option. Click OK at the confirmation screen that appears.
On Facebook, it's better to provide your actual birth date. If this bothers you, you should remove your birthdate from your profile. However, this will make it more difficult for others to find your page if they know your exact date of birth.
To alter your birthdate, go to the upper right corner of Facebook and click on your profile picture.
