Never forget a birthday again with this perpetual calendar. Get one of these up on your wall, then add names over the years to develop an indispensible catalogue of whose special day is when. Alternatively this makes a great gift, just put the calendar in the envelope provided and pop it in the post.  When purchasing for a gift we recommend writing in your own birthday before posting. Each page features a different New Zealand native bird drawing, and displays two months of birthdays.
