You can change your birth date in Facebook settings, but Facebook limits how often you can do it

To change your age on Facebook, go to your profile, select "Edit profile," find the birth date field, and update it. Facebook allows you to change your birth date once every 60 days. If you need to change it more frequently or if Facebook has locked the field, you may need to contact Facebook support or wait out the 60-day window.

The birth date you enter affects what you see on Facebook — your age determines which ads you see, which groups you can join, and whether certain content is available to you. If your birth date is wrong, changing it updates these settings immediately.

Key Takeaways

  • You can change your birth date through your profile settings under "Edit profile," then select the birth date field.
  • Facebook enforces a 60-day waiting period between changes, so you cannot update your age more than once every two months.
  • If the birth date field is locked or grayed out, you have either recently changed it or Facebook has restricted the field for security reasons.
  • Changing your birth date does not affect your account security or login information, only the age-related content and ads you see.

How to find and edit your birth date

Open Facebook and go to your profile by clicking your name or profile picture in the top right corner. Once on your profile, look for the "Edit profile" button, usually located near your cover photo. Click it to enter edit mode.

Scroll down until you see the "Basic information" section. Your birth date appears here. Click on the birth date field to open a date picker. Select the correct month, day, and year, then click outside the field or press Enter to save. The change takes effect immediately.

The 60-day rule and what happens if you hit the limit

Facebook restricts how often you can change your birth date to once every 60 days. If you try to change it before 60 days have passed since your last change, Facebook will show a message saying you cannot update it yet and will tell you when you can try again.

This limit exists to prevent account misuse and fraud. If you need to change your age before the 60 days are up, you can contact Facebook support through the Help Center, though they may ask you to verify your identity or provide documentation before overriding the restriction.

Why your birth date field might be locked

If your birth date field appears grayed out or locked, one of three things is usually happening: you changed it within the last 60 days, Facebook flagged your account for security reasons, or you set your account to hide your birth date from other users.

To check if you have hidden your birth date, go to "Edit profile" and look for privacy settings next to the birth date field. If it shows a lock icon or "Only me," click it and change the setting to allow edits. If the field remains locked after checking privacy settings, wait 60 days from your last change or contact Facebook support.

What changes when you update your age

Updating your birth date changes the age Facebook uses to show you ads, determine group membership, and filter content. If you set your age to under 18, Facebook removes certain features like the ability to see or use some advertising tools. If you set it to 18 or older, those features return.

Your birth date does not affect your password, email, phone number, or any other account security settings. Changing it is purely a profile update and does not log you out or require you to re-enter your password.

Changing your age on mobile versus desktop

The process is nearly identical on mobile and desktop. On a phone or tablet, tap your profile picture, then tap "See your profile." Tap "Edit profile," scroll to "Basic information," and tap the birth date field to change it. The date picker works the same way as on desktop.

Some users find the mobile interface slightly slower to load, but the 60-day restriction and all other rules apply equally. If you run into problems on mobile, try switching to the desktop version of Facebook through your phone's browser.

What to do if you cannot change your birth date

If you have tried to change your birth date and Facebook will not let you, first check whether 60 days have passed since your last change. If they have and the field is still locked, try logging out and logging back in, or clearing your browser cache and cookies.

If those steps do not work, go to Facebook's Help Center, search for "birth date," and select "Report a problem." Describe what happens when you try to change it — whether you see an error message, the field is grayed out, or something else. Facebook support can investigate and may be able to unlock the field if there is a technical issue or if you can verify your identity.

Frequently Asked Questions

Can I change my age without other people seeing it?

Yes. When you edit your birth date, you can set who sees it by clicking the privacy icon next to the field. You can choose "Only me," "Friends," "Public," or a custom list. Changing the privacy setting does not affect the 60-day restriction on how often you can change the date itself.

Does changing my birth date affect my Facebook friends or notifications?

No. Your friends will not be notified that you changed your birth date, and it does not affect your friend list, messages, or any notifications. If your birthday is coming up and you change the date, Facebook will not send birthday reminders for the old date.

What if I set my birth date wrong when I created my account?

You can change it the same way you would any other time — through "Edit profile" and the birth date field. The 60-day rule applies even if the original date was a mistake, so you can only change it once every 60 days after your first update.

Can I hide my birth date completely instead of changing it?

Yes. In "Edit profile," click the privacy icon next to your birth date and select "Only me." This hides your birth date from everyone except you. Facebook will still use the birth date you entered for age-related ads and content filtering, even if it is hidden from your profile.

What happens if I set my age to under 13?

Facebook does not allow accounts for users under 13 in most countries. If you change your birth date to show you are under 13, Facebook may disable your account or ask you to verify your age. If you created your account as a minor and are now older, you can update your birth date without issue.
