Go to Settings and privacy, then Your account, then Account information, then Birth date. Enter your birthday and choose who can see it. X (formerly Twitter) lets you set a different audience for your month and day than for your birth year. Save changes and you're done.

Why your birthday matters on X

I get asked this a lot, so let's clear it up straight away. X uses your birthday mainly to confirm you meet the minimum age to use the platform. It is not shown on your profile by default, and you control who sees it.

Some people also like having it set so friends can wish them well on the day, if they choose to make it visible. Either way, it only takes a couple of minutes to sort out.

Where to find the birthday setting

You will not find your birthday under your main profile edit screen. It lives inside your account settings, which trips a lot of people up.

On the app or the website, you need to go through Settings and privacy first, then into Your account, then Account information. Birth date sits inside that section.

Step by step on the X app

Here is exactly what to do on your phone.

  1. Open the X app and tap your profile picture in the top left.
  2. Tap Settings and privacy.
  3. Tap Your account.
  4. Tap Account information.
  5. Tap Birth date.
  6. Enter your month, day, and year.
  7. Choose who can see your birth date and who can see your birth year separately.
  8. Tap Save to confirm.

Step by step on desktop

If you prefer using a browser, the steps are nearly identical, just on a bigger screen.

  1. Log into X on your browser.
  2. Click More in the left hand menu.
  3. Click Settings and privacy.
  4. Click Your account, then Account information.
  5. Click Birth date.
  6. Fill in the date and set your visibility preferences.
  7. Click Save changes.

Choosing who sees your birthday

X splits visibility into two parts: your month and day, and your birth year. You can set these differently, which I think is a sensible touch.

Your options typically include only you, your followers, people you follow, or everyone. If you are not fussed about people knowing your exact age, you might show the month and day but keep the year private.

I would suggest keeping the year hidden unless you have a specific reason not to. It is a small detail, but it reduces the amount of personal information floating around publicly.

Can you change your birthday once it is set?

Yes, you can edit it again later by following the same steps. Go back into Birth date under Account information and update the details.

If you entered the wrong date originally, or your visibility choice does not feel right anymore, just go back in and adjust it. There is no limit mentioned by X on how often you can revisit this setting, though it is meant for correcting genuine mistakes rather than constant changes.

What if the birth date option will not save

Sometimes people find the save button does not respond, or the date reverts back to blank. If this happens, try closing the app fully and reopening it, then going through the steps again.

On the browser, a simple refresh of the page often fixes it. If neither works, check that your app is updated to the latest version, since older versions sometimes have bugs in settings menus.

If none of that helps, this is a case where I would say plainly: the problem sits with X's app at that moment, not with anything you are doing wrong. Try again later or contact X support directly.

A quick note on age verification

X may ask you to confirm your age through other means in some regions, separate from just entering a birth date in settings. This is part of broader age assurance rules that vary by country.

I cannot tell you exactly which verification method you will see, since X rolls these out differently depending on location and account history. If you are prompted for extra verification, follow the instructions shown on your own screen rather than assuming it will match what someone else describes.

Final thoughts

Setting your birthday on X is a short job once you know where to look. The setting hides inside Account information rather than your public profile, which is the main reason people struggle to find it.

Take the extra few seconds to set your privacy preferences for both the date and the year. It is a small step, but it keeps you in control of what others can see about you.

Frequently asked questions

Where is the birthday setting on X

It is under Settings and privacy, then Your account, then Account information, then Birth date. It is not part of your main public profile editor, which is why many people miss it at first.

Can other people see my birth year on X

Only if you choose to show it. X lets you set separate visibility for your birth month and day versus your birth year, so you can share one without revealing the other.

Can I change my birthday after saving it on X

Yes, go back into Birth date under Account information and edit it again. There is no stated limit on how often you can update it, though it is meant for corrections rather than frequent changes.

Why will my birth date not save on X

This is usually a temporary app or browser issue. Try closing and reopening the app, refreshing the page, or updating to the latest version before trying again.
