To manually add birthdays to Google Calendar, the user has to add the name, birthday and email address of another gmail user to Google Contacts.

Google is finally making it easier to add birthdays to Google Calendar. The service is getting a new birthday event type that removes all unnecessary event properties.

At the moment, birthdays that appear in Google Calendar are based on Google Contacts information, but manual creation is now coming.

Google is making it easier to create birthday reminders in Google Calendar. The new Google Workspace update is currently rolling out and should become available in the next couple of weeks.

You can share your Google Calendar with others, making it easier to keep track of friends' and family members' schedules. You must use a computer, though.
