How long can contact lenses be stored in same solution without wearing them?

When I am not wearing contacts, how long can I store the contact lenses in the solution without replacing it?

You'd better change the solution everyday. Some people will store their lens in the same solution for 3 days. Anyway, you should change the solution at least once a week.
