The feature is optional and users have control over who can see it. The birth year setting is separate from the birth month and day setting, so users can choose how much or how little they want to share.
When it is someone’s birthday, Twitter will splash animated balloons across that person’s profile page.
Comedian and actor Kevin Hart is helping the social media site kick off the new feature.
The move comes as Twitter continues to position itself as a platform where people can celebrate both personal and public events. Recently, the hashtag ‘#LoveWins’ became wildly popular on the site after the Supreme Court ruled that same-sex marriage is a right.
