After having your ears pierced how long do you keep the earring in for?

Hi, I just got my ear lobes peirced yesterday and i was told i had to leave them in for six weeks. After the six weeks i can take them out but i always have to have a stud in for half a year, after half a year you can wear hanging earings. If you got your ear cartilage peirced you need to leave them in for 8-12 weeks. after that you cant take them out but you always have to have a stud in for a year. then you can wear dangly earaings. thanks bye
