How do I change my birthday and choose who I share it with on Facebook?

 

To change your birthday:

1. Go to your profile and click About.
2. In the left column, click Contact and Basic Info.
3. Scroll down and hover over Birth Date or Birth Year, and then click Edit to the right of the info you'd like to change.
4. Use the dropdown menus to change your birthday and use the audience selector to choose who can see it.
5. Click Save Changes.

You can change who can see your birthday by adjusting the audience. 

There are 2 audience selectors next to your birthday: one for the day and month and one for the year. Friends won't get a notification about your upcoming birthday if you don't share the day and month with them.

Note: There's a limit to how many times you can change your birthday. If you've recently changed it, you may have to wait a few days before you can edit it again.
