How to change your birthday on X (and the hard limit)

#Quick answer

To change your birthday on X (formerly Twitter), go to your profile, tap or click Edit profile, open the Birth date section, and set the Day, Month and Year you want, then save. The route is identical on x.com, iOS and Android. While you are in there, set the two visibility controls, because the birth year and the birth day and month are separate fields with separate audiences.

The part no tutorial mentions: X caps how often you can do this. Its own help page says you "will only be able to change these settings a few times," and it never publishes the number. So this is not a field to poke at.

#Change your birth date, step by step

These steps come straight from X's help page on customizing your profile.

1. Sign in at x.com or open the X app for iOS or Android.
2. Go to your profile. On the web that is your avatar in the left sidebar; in the app it is the profile icon in the top menu.
3. Tap or click Edit profile. This is the same screen that holds your name, bio, location, website, header and profile photo.
4. Open the Birth date section.
5. Select or change the Day, Month and Year.
6. Set who sees it. You get two separate controls, one for the year and one for the day and month. On the web they are visibility icons; in the app it is a "Who sees this" row.
7. Save.

That is the whole flow. If you have never added a birth date, the same screen is where you add one for the first time, and adding it is often the fix for a different problem entirely, which the sensitive-media section below covers.

#The limit nobody warns you about

X's help page contains one sentence that matters more than the steps: "Birth date (you'll be able to choose who sees this information, but can only change the settings a few times.)"

A few times. Not unlimited, and X does not say whether that counter covers the date itself, the visibility settings, or both. There is no counter in the interface showing what you have left, and no documented way to reset it.

The practical rule: decide the date and the two audiences before you open the screen, make one edit, and leave it alone. People burn their allowance by toggling visibility back and forth to see what the profile looks like from outside, then find they cannot fix a typo in the year later. If you want to know how your profile reads to a stranger, open it in a logged-out browser window instead of testing settings.

One more lock worth knowing: if X Support set or confirmed your date of birth while handling an appeal, that value is treated as verified, and the edit screen will not let you overwrite it. At that point the only route is Support again, not the settings menu.

#Who can see your birthday (year and day are separate)

X splits the birth date into two independently controlled fields, and this is the most useful thing on the page. Per X's birth date visibility help, each of them offers the same five audiences:

Two notes from the same page. Anyone who entered a birth date after January 2022 got Only you as the default, so if you never touched this, your birthday is almost certainly hidden already. And if you are under 18, the birth year visibility is forced to Only you until you turn 18.

That split is what makes this genuinely useful. Set the day and month to Public if you want the birthday wishes, and keep the year on Only you so your age is not sitting in public view next to your handle. Identity checks routinely ask for a date of birth, so a public birth year is free material for anyone building a profile of you. The same logic applies to the rest of your profile, which is why the X account security basics start with what you volunteer, not with your password.

#How to remove your birth date

Removing is not the same as hiding, and the web flow is fiddly:

• On x.com: Edit profile, click the Birth date section, then set all three dropdowns back to their default Day, Month and Year values. X states that you have to clear all three fields for the removal to take.
• In the iOS or Android app: Edit profile, Birth date, then tap Remove birth date.

Before you do it, read the next section. An empty birth date field is not neutral in 2026.

#What a wrong or missing birth date costs you

This is where the stakes changed, and where the guides still ranking for this query are a couple of years behind.

Sensitive media stops loading. X states that viewers under 18, or viewers with no birth date on their profile, cannot click through to media marked as sensitive. If posts keep showing you a warning screen you can never open, a missing birth date is the first thing to check, not your content settings. We walk the full setting in how to turn sensitive content on or off on X.

Age assurance reads your self-attested age. X is required by the UK's Online Safety Act, the Irish Online Safety Code, the EU Digital Services Act and Australia's Online Safety Act to estimate or verify whether users are over 18. Its age assurance page lists the signals it uses, and the very first one is self-attested age: "if a user previously indicated that they are under 18." Enter a joke birth year once and you may hand X a signal that defaults you into restricted settings later. The listed appeal route is contacting X Support, and the alternative proof paths are a live selfie for facial age estimation or a government ID, which is the same machinery covered in X ID verification.

Under 13 is a hard floor. X requires account holders to be 13 or older. Per its account restoration page, an account identified as having signed up under 13 is locked, and regaining access once you meet the age requirement means giving up data: posts, Likes and Direct Messages from before you turned 13, plus profile details other than your handle and date of birth, Moments, Lists and saved collections. The restoration itself can take up to 72 hours, and eligibility expires after 30 days. So a birth year typed carelessly into the signup form is not a small mistake, and creating an X account is the point to get it right.

#When the field will not save

Work through these in order before you assume the account is broken:

1. You have used up the changes. The most likely answer, and there is no self-serve reset.
2. Support already set the date. A date confirmed during an appeal is locked to the edit screen.
3. The value fails the age check. A date that puts the account under 13 will not be accepted.
4. Client glitch. Try the other surface. If the app refuses the edit, do it at x.com, and vice versa. Log out and back in if the profile screen looks stale.
5. Only the visibility saved. The date and the two audience controls are separate saves, and it is easy to change one and assume the other went with it. Reopen Edit profile and confirm what actually stuck.

If none of that moves it, the escalation is X Support rather than another attempt, because repeated failed edits do not earn you extra allowance.

#Bottom line

Changing your birthday on X takes four taps: profile, Edit profile, Birth date, save. The parts that matter are the ones around it. You get a handful of changes, and X will not tell you how many are left. The year and the day and month have separate audiences, so the sensible setup is a public day and month with a private year. Removing the date entirely has a cost, because a profile with no birth date cannot open media marked as sensitive. And an inaccurate date is not harmless in 2026, since a self-attested age under 18 is one of the signals X's age assurance reads before it decides what you are allowed to see.

Get it right once, set the two visibility controls deliberately, and move on to work that compounds. If that means posting more consistently than you manage by hand, X-Autopilot runs from your own logged-in browser on your Mac, so your session cookie never leaves your machine, which is a smaller detection surface than handing your login to a cloud tool, though no browser-based automation is sanctioned by X's rules.
