You can change your birthday on Facebook, but only once per year
Facebook lets you change the birthday on your account, but the platform limits how often you can do it. You can change your birthday once every 60 days. If you've already changed it recently, you'll have to wait until that window closes before you can change it again.
The reason for this limit is to prevent account takeovers. If someone gains unauthorized access to your account, they can't repeatedly change your birthday to lock you out or cause confusion. The 60-day window is Facebook's way of balancing your ability to fix mistakes with account security.
Key Takeaways
- You can change your birthday through Settings on any device, and the change takes effect when ready.
- Facebook limits birthday changes to once every 60 days to protect your account from unauthorized access.
- Your birthday visibility is separate from changing it — you control who sees your birthday through privacy settings.
- If you've hit the 60-day limit, you'll see a message telling you when you can change it again.
- Changing your birthday does not affect your account security, login information, or any other account details.
How to change your birthday on Facebook
Open Facebook and go to the menu in the top right corner (the three horizontal lines on mobile, or the down arrow on desktop). Select Settings and privacy, then Settings. On the left side, click Personal information.
Find the Date of birth field. Click on it to edit. Enter your correct birthday using the dropdown menus for month, day, and year. Click Save changes when you're done. The new birthday appears on your profile when ready.
If you see a message saying you can't change your birthday yet, you've already changed it within the last 60 days. The message will tell you the exact date when you can change it again.
What happens when you change your birthday
Your birthday changes everywhere on Facebook — your profile, your timeline, and the birthday reminders your friends receive. If you had a birthday coming up and you changed the date, your friends won't be reminded about the old date anymore. They'll get a reminder on your new birthday instead.
Changing your birthday does not reset your account, log you out, or affect your password. It's a straightforward profile update, the same as changing your name or location. Your messages, photos, and friends list stay exactly as they are.
Controlling who sees your birthday
Your birthday visibility is separate from changing it. You can change your birthday and still control who sees it on your profile. Go back to Personal information in Settings and look for the privacy icon next to your date of birth — it usually looks like a lock or an eye.
Click that icon to choose who can see your birthday: Public (everyone), Friends (only people you're connected with), or Only me (hidden from everyone). You can also hide your birthday entirely by selecting Only me and then unchecking the box that says "Show my age on my profile."
If you can't change your birthday
The most common reason you can't change your birthday is the 60-day limit. If you've already changed it once this year, you'll have to wait until the window closes. Facebook will show you exactly when you can make another change.
If you're seeing a different error message, try logging out and logging back in. Clear your browser cache if you're on desktop, or force-close and reopen the Facebook app on mobile. If the problem persists, contact Facebook through the Help Center — go to Settings, scroll down, and select Help and support.
Why Facebook limits birthday changes
The 60-day limit exists because your birthday is tied to account recovery. If you forget your password, Facebook can use your birthday to verify your identity and help you regain access. If someone hacks your account, they could change your birthday repeatedly to lock you out of recovery options.
By limiting changes to once every 60 days, Facebook makes it harder for attackers to use your birthday against you. It also gives you enough flexibility to fix genuine mistakes without leaving your account vulnerable.
Frequently Asked Questions
Will my friends get notified when I change my birthday?
No, your friends won't see a notification that you changed your birthday. However, if you change the date to a day that's coming up soon, they may get a birthday reminder for the new date. If you hide your birthday entirely, they won't get any reminder.
Can I change my birthday more than once every 60 days?
No. Facebook enforces a strict 60-day limit between birthday changes. If you try to change it before that window closes, you'll see a message telling you when you can change it again. There's no way to bypass this limit.
Does changing my birthday affect my Facebook account age or history?
Changing your birthday does not affect how old your account is or any of your account history. Your posts, photos, and friends list remain unchanged. The only thing that changes is the birthday displayed on your profile.
What if I entered my birthday wrong when I created my account?
You can correct it using the same steps to change your birthday. If you've already changed it once recently and hit the 60-day limit, you'll have to wait until that window closes. In the meantime, you can hide your birthday from your profile so the incorrect date isn't visible.
Can I delete my birthday from Facebook entirely?
You can hide your birthday from your profile by setting its visibility to Only me, but you cannot delete it completely. Facebook requires a birthday on file for account recovery and age verification purposes. You can keep it hidden while still maintaining the information in your account.
