The update adds two birthday-specific lenses: one that you can only access on your birthday and one you can use to wish a happy birthday to your friends. On a friend’s birthday, the birthday cake emoji will appear next to his or her username along with the text “double tap to birthday snap.” Double tapping will open the camera, where you can activate a birthday lens (pictured below) to send.
On your birthday, you’ll be able to unlock a different birthday-themed lens. You can change your birthdate in the app’s settings to get an early peek at the lens, but Snapchat warns you’ll only be able to change it within the app a limited number of times.
Tuesday’s update also added a small change to the app’s time filter. Tapping on the time will now change the filter to the current date, rather than just the time.
Snapchat’s “Birthday Party” update comes just a day after Facebook rolled out a new birthday video feature.
