A birthday is the date when someone is born; some IndieWeb sites display their owner’s birthday, or provide a special display or custom theme on the date and month of the birthday itself. Some silos’s user profiles have a birthday field that you can (or must) enter, and some prominently alert your friends on the month and day of your birthday, like Facebook’s "BIRTHDAYS THIS WEEK" feature at the top of their events page.
Sharing your birthday on your website lets you inform the web of when your birthday is. More people may say "happy birthday" to you. If someone forgets your birthday, they can refer to your website.
Birthdays are often used as part of the security information on various sites, and thus revealing your birthday may place you at more risk of your account on such sites being compromised.
Ways to share your birthday on your site include:
- Having a countdown to your birthday
- Publishing your birthday on your About page
- Sharing your birthday using a h-card
- Posting an announcement on your birthday as a post

IndieWebCamp sessions about birthdays:
Birthdays are often used as part of a person's identity and thus publishing a precise accurate birthday pose an identity theft security risk. As a result, people at some IndieWebCamps have self-reported as using non-real birthdays on silos.
Birthdays are often used by social networks to create spurious notifications - see Friendster's line in this video

I created an account for my podcast, @ProRataPod. Noticed the "birth date" was public, so changed it to July 2018, which is when the podcast launched. Now I'm locked out because I'm "too young" to manage a Twitter account." @danprimack July 22, 2019

changed the year to 2006 – the actual year we legally started the business (unlike 1991 which was the year I was born). […] I received a warning […] I went ahead and confirmed […] “Your account is locked.”
