How to Change Your Birthday on Facebook (And What to Know Before You Do)
Facebook stores your birthday as part of your profile — and like most profile details, it can be edited. But the process comes with a few important caveats that catch a lot of users off guard. Here's exactly how it works, where the limitations are, and what affects whether the change goes smoothly for you.
Where Facebook Stores Your Birthday
Your birthday lives in the About section of your profile, under Basic Info. It's separate from your timeline posts, your name, and your contact details — though Facebook does use it in a few interconnected ways: birthday reminders for friends, age-gating for certain content, and in some cases, account recovery verification.
That last point matters. If your birthday is linked to account security, changing it can have downstream effects worth knowing about.
How to Change Your Birthday on Facebook (Step-by-Step)
On Desktop
- Go to your Facebook profile
- Click Edit profile or navigate directly to your About tab
- Select Basic Info from the left-hand menu
- Find the Birthday field and click the Edit (pencil) icon
- Update the month, day, and year using the dropdown menus
- Choose your privacy setting for who can see it (more on this below)
- Click Save
On Mobile (iOS or Android)
- Tap your profile picture to go to your profile
- Tap Edit profile
- Scroll to find Customize your intro or go to the About section
- Tap Basic Info
- Update your birthday details
- Tap Save
The mobile interface varies slightly depending on your app version and whether you're using the standard Facebook app or Facebook Lite, but the core path — Profile → About → Basic Info → Birthday — remains consistent across versions.
The Change Limit: This Is Where Most People Get Stuck ⚠️
Facebook restricts how often you can change your birthday. Specifically, you can only change it a limited number of times, and after a certain number of edits, the option may be locked or grayed out.
If your birthday field is uneditable, you'll typically see a message indicating the change limit has been reached. At that point, your options are:
- Submit a request to Facebook Support through the Help Center
- Provide identity verification — Facebook may ask for a government-issued ID to confirm your actual date of birth before unlocking the field
This restriction exists primarily to prevent misuse — for example, users cycling through ages to bypass content restrictions or to game age-based features on the platform.
Privacy Settings for Your Birthday 🎂
When you update your birthday, Facebook gives you control over who sees it. The options typically include:
| Visibility Option | What It Means |
|---|---|
| Public | Anyone on or off Facebook can see it |
| Friends | Only your confirmed friends see it |
| Friends except… | Friends minus specific people you exclude |
| Only me | Hidden from everyone but you |
| Custom | Fine-grained audience selection |
You can also control the month/day separately from the birth year — meaning you could let friends see your birthday for the annual reminder without revealing what year you were born. Many users prefer this configuration for privacy reasons.
What Affects Whether the Edit Works Smoothly
Not everyone will have the same experience updating their birthday. Several factors come into play:
How many times you've changed it before — If you've edited it multiple times on the same account, the field may already be locked before you try again.
Account age and standing — Newer accounts or accounts flagged for policy issues may face stricter restrictions on profile edits.
App version vs. browser — Some users find that editing via the desktop browser offers more reliable access to the Basic Info section than the mobile app, particularly when the app hasn't updated to the latest version.
Whether your birthday is tied to account security — If Facebook uses your birthday as part of identity verification (common in certain account recovery flows), you may encounter additional friction or confirmation steps.
Regional platform differences — Facebook's interface and feature rollout isn't always uniform globally. The exact UI path can differ slightly depending on your region.
What Happens After You Change It
Once saved, the updated birthday becomes part of your profile immediately. Friends who check your About page will see the new date. The birthday reminder system — which notifies friends on your birthday — will update to reflect the new date as well.
One thing that doesn't change automatically: posts or memories already tied to past birthdays. Facebook's "On This Day" and memory features are stored separately, so old birthday posts from friends won't be retroactively removed or reassigned.
If you changed the year specifically, keep in mind that Facebook may use your birth year to determine eligibility for certain types of content or advertising categories — that's a platform-level data consideration that operates separately from what friends see on your profile.
When Facebook Won't Let You Change It Yourself
If the field is locked and self-service isn't available, the path forward is through Facebook's official support channels. The Help Center has a dedicated form for birthday change requests. Be prepared for the process to take time and potentially require ID — Facebook's identity review process isn't instant, and response times vary.
The outcome depends on your account history, the documentation you provide, and whether your request falls within what Facebook's support team considers a valid correction versus a policy violation.
How straightforward the process ends up being really comes down to your specific account's history and current status — something only visible from inside your own account.
