Is it uncommon not to hear anything after a home inspection?

After our home being on the market for quite some time, we finally got an offer. We are under contract and the buyers had 10 days to schedule a home inspection, which they did and that was done on day 9. The contact states they have three days to contact the sellers (us) and inform them of their decision. It does not state business days or actual days. I just feel like if everything was okay, we would have heard something by now (the home inspections was on Thursday it is now Saturday.) It is also a holiday weekend... Anyone who has ever been through selling a home care to share your experience? We are located in Ohio.
