Magnetic Learning Calendar with Weather Station 55 PCS (15” X 12” Wall Mountings Ready)

Hi. Is the entire background board magnetic or just the spot where it is suppose to be placed? Also, are the dates/weather pieces fully magnetic too?

Can you buy replacement numbers?

Is the board itself magnetic (will it stick to the fridge or a magnetic whiteboard)?

Do you have to hang this with the hook/string, or can it attract magnetically to a refrigerator?
