Where do I find a table / listing of all currently airing anime series? Is there a website or any kind of document that shows all currently airing series in Japan? Airing dates and times would be great too.
I use http://countdown.mandragon.info/ which shows the day and time of the next episode for currently airing shows and dates for shows that will be broadcast soon.

Edit: This site is now down, so I'll recommend another one I use often: http://anichart.net/
