How to Hide Your Birthday on Facebook

On a Phone or Tablet

Open Facebook on your phone or tablet. This is the blue icon with a white "f" inside. You'll find it on your home screen or in your app list.

Tap the menu icon ☰. This is the three horizontal lines at the top-right (Android) or bottom-right (iPhone/iPad) corner of the screen.

Scroll down and tap Settings & Privacy. It's just about halfway down the menu.

Tap Settings. This is the first option in the Settings & Privacy submenu.

Tap Profile Information. This option is under the "Audience and Visibility" header.

Tap Edit next to "Basic Info." You'll find this about halfway down the menu. Now you'll see your birthdate and birth year.

Tap the privacy menu next to your birth date. You'll need to adjust the privacy of your birth date (month and day) and birth year separately. The menu icon says the current privacy level, such as Public or Friends.

Select Only me from the menu. This tells Facebook not to show your birthdate to anyone who looks at your profile. It will still be visible to you. If you're okay with people you're friends with knowing your birthday, you could select Friends here instead.

Make your age/birth year private (optional). If you'd also like to hide your year of birth (and your age) from your profile, tap the privacy menu next to your birth year and select Only me (or Friends, to make it friends-only) as well.

Tap Save. Tap this option at the top-right corner to save your changes. Your new preferences will take effect immediately.

On a Computer

Go to https://www.facebook.com in a web browser. Facebook will open to your News Feed page if you're logged in. If you aren't logged in, follow the on-screen instructions to sign in now.

Click your name tab. Look for a small round version of your profile photo in the upper-right area of the page. This takes you to your profile.

Click the About tab. It's near the top of your profile, but below your cover image.

Click the Contact and Basic Info tab. It's in the left panel.

Click the pencil icon next to your birthday. You'll see this under the "Basic Info" header.

Click the privacy menu next to your date of birth. Your birthdate is actually separated into two sections—the month and date of your birth, and your birth year. You must control the privacy level of each of these two details separately. The privacy menu is the menu directly to the right of your birth date. The menu states the current privacy level of your birthdate. For example, if your birthdate is public, you'll see Public on the menu.

Select Only me as the privacy level. This ensures that nobody can see your date of birth on Facebook. If you're okay with friends seeing your date of birth but not random strangers, you can choose Friends instead.

Make your age/birth year private (optional). If you also want to hide your age from your profile, click the privacy menu next to your birth year and select Only me (or Friends, to make it friends-only).

Click the Save button. It's at the bottom-right corner of this section. Your changes are now saved.
