E4200 Parental controls: What does Cisco define as a "School Night"

Question

I loved my WRT610N, but unfortunately a firmware "upgrade" killed its ability to limit device access to certain hours, so I had to buy a new router.
My brand new E4200 stumbled out of the gate when the Mac app on the setup CD declared it cannot be read by my operating system, OS X 10.7.1 (Lion). I had to laugh, but I prefer to do things through the web interface anyway.
Whether or not I hang on to this router or return it will mostly depend on if I can get it to block access to the Internet for certain devices at certain times of the day.
The parental control interface surprisingly shoddy -- in fact it looks as if it isn't quite done -- but if it will do the job, it will be nice to be able to turn off internet access on a device by device basis once again.
Here's my question though:
Does anyone know how Cisco's E4200 router defines "Weekends" and "School nights?"
A simplistic (and incorrect) definition of a weekend for a router would be: Saturday and Sunday.
That would be incorrect because Friday, a "School Day" is a night where you would want later access, and Sunday, a "Non-school day" is when you would want access to shut off earlier because they need to get up for school on Monday morning.
Of course Sunday night I'll learn what time devices are barred, but I don't want to have to wait until the following Friday to learn whether or not they got Fridays right. There is a limited window where I can return the router and I don't want to push against it.

Answer 1

So are you saying that the time schedule defines weekends as Saturday & Sunday instead of Friday and Saturday?
The trouble with the Internet Access Policy is that each of groups only allow for 10 devices. Each of my kids has a desktop computer and an iPod touch, and the older kids also have laptops and iPads. Oh, and we have 7 kids. Add to that the family gaming systems that access the Internet, and you can see the problem with a 10 device limit.
It takes 4 groups just to enter all the kids' gadgets, and unlike the "Parental Controls" list, which displays both Mac addresses and computer names of all devices on the wireless network for me to choose from, the "Internet Access Policy" only gives 10 boxes for entering Mac Addresses, something I have to go out and get then carefully enter. And annoyingly, the boxes aren't even long enough to display a full MAC address once you have entered it, so you have to click in it and scroll with cursor keys to find typos.
In short, it's not that the Internet Access Policy is "more complicated," it's that it is tedious and limited.
This is why I am hoping the Parental Controls feature will be adequate.
Unfortunately, I can't find documentation that tells me what the router defines as a "Weekend." The help is certainly not helpful, in fact, it is kind of humourus ("To never block Internet access, select Never."). Brilliant.
On Sunday night, I'll be able to discover if the router considers Sunday night as a "School Night." If it does, then I have to wait for Friday to find out if that school day is considered by the router to be a "Weekend."
But I was hoping someone here knew already -- either from experience or from documentation somewhere.
By the way, I'm also a bit paranoid about using the "Internet Access Policy." That's what I was using on my former router, then I did a firmware upgrade and every MAC address entered in the IAP could not access the Internet anymore -- even during the times they should have been allowed.
