How do these Okinawa (sightseeing/facilities) passes work?

Hi guys,

I'll be travelling to Okinawa for about a week and just found these Okinawa passes on Klook. One e.g. says that I can use it for the aquarium plus 4 other facilities. Can I only use the pass on one day or can I use this pass on several days, so let's say I visit 2 or 3 facilities a day?

Thx in advance!
