Activate/deactivate a form at various time of the day/night?

I have been trying to find a solution for this problem for some time. I have a membership application form on my site. I would like to make it available only during day time, let’s say from 8am to 8pm. Even better if I could schedule it on a weekly basis too so that it is available only when the association is closed (when it’s open they can come and apply for the membership in person).
Is there a way to do this with GF?
