You can add your birthday and marital status to the Personal Details section, found in the Additional Info section on your profile. Fields in this section will only be visible if you enter information. This section doesn't appear on your public profile. To add personal details on desktop:
- Move your cursor over Profile at the top of your homepage and select Edit Profile.
- Scroll to the Additional Info section.
- If you've never added personal details, you'll first want to add a Personal Details section. Under your profile summary at the top, you'll see 2 sections that you can add to your profile. If you don't see Personal Details here, click View More to see a full list of sections you can add.
Note: Click the Padlock icons to control the visibility of this information. You can make it visible to either only your connections, your network (1st, 2nd, 3rd degree connections and those you share Groups with), or everyone on LinkedIn.
If you remove all information from this section, the Personal Details placeholder header may still show up. However, this text won't show up when others view your profile, and it'll also be removed once you refresh the page.
