Here is the graphic-style weekly calendar of shows that are on this January, with highlights of staff and cast, and this season with the total number of episodes for each series. Here is my preview of the new shows. Dates and times are for the first TV or Web broadcast of a show, or the release date of an OAV.
Names of staff and cast members, etc., are linked to further information about them, largely in the Anime News Network Database, but also in Wikipedia or the Hashihime Seiyuu Gallery.
Information is from MoonPhase, Anime News Network, anidb.info, official sites, and especially Shoboi Calendar.
Shoboi Calendar gives a future schedule for each show, and in almost all cases it seems to be an accurate prediction of how many episodes there will be. I have added a "?" to totals where Shoboi does not explicitly state that the last episode they show is really the final episode.
