birthday

Jump to: navigation, search

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.

Why

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.

Why not

Security risk

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.

How

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

IndieWeb Examples

  • Ashton McAllan on http://acegiak.net/ using dt-bday in her h-card on her home page since (????-??-??)
  • Aaron Parecki publishes the month and day of his birthday using dt-bday on his home page h-card since 2016-02
  • Sebastiaan Andeweg added some code to display a cake-emoji next to the profile picture on his main h-card, which also advertises his birthday in mf2, but only on the day itself.
    • <data class="dt-bday" value="--MM-DD">🎂</data>
  • Martijn van der Ven displays his age and a countdown to his birthday on his website. The countdown, when parsed for microformats gives the time-of-birth as bday exact to the minute.
  • capjamesg has a temporary banner on his website counting down to his birthday.

Issues

Security

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.

Criticism

Birthdays are often used by social networks to create spurious notifications - see Friendster's line in this video
