Saturdays actually work, and I get sometimes more views then than on my actual upload day (tuesday)! However, there's the side effect of not being around to promote that new page if you're not home by then, so it's got its cons too.
Always keep timezones in mind. Tapas uses PST but it's good to try to get as close to midday in the rest of the US too, as long as you can also be around to post it on the forums, social media, etc.
