Getting all my historical periods and conquests confused

Post-exilic, pre-exilic, Babylonian, Persian, sources J and E and D and P. It's getting late and my braincells are frying. So that I can start afresh tomorrow, can anyone recommend a really easy but authoritive and trustworthy Old Testament Bible Timeline, online, so that I can refer to this when I mix up my epochs and peoples.

Thank you

Do you remember those wooden rulers you could get as a child with the history of all our Kings and Queens, which proved to be a great cheat in history classes, I could do with something like that!
