When does the GitHub education pack tools start their expiry time?

I just applyed for the Student’s Education Pack. I was wondering if the tools will start expiring the moment I get approved, or only if I start using the tool, because I would love check every single tool and use all of them one by one multiple at a time and experiment my skills. But some have very short time limits.

So will it expire within that time since I get approved or only if I start using the tool?
