on computer with internet browser open up google calendar
click on gear emblem settings
click setting
click on calendar (blue color)
click Browse interesting calendars »(blue color)
click More (blue color)
on Contacts' birthdays and events ..click subscribe

than on your Device
open up the calendar app
hit the three dots
hit Calendar to display
put a check, Contacts birthday and events
hit Calendar to Sync
hit ok
then your done

Do your contacts on your phone have their birthdays added to them? If yes, then I don't know, if not then add them mantually.
