All years are Common Era unless otherwise indicated (years given for other calendars- e.g., Jewish, Islamic, Chinese- will be the current year for no particular reason, unlike CE years, which generally refer to historic dates). Most calendar links are to external websites, though a very few will be to other sections of this site. Movie release dates will generally be for wide (national) release unless, on rare occasions, noted to be limited releases. If a movie listed here specifically says (wide), it will be because it has already been in limited release from an earlier date. DVD links (generally to Amazon) will be for widescreen releases whenever possible (if you prefer fullscreen, please check Amazon for such an edition; the widescreen pages I link to should have their own links to other editions of the DVD). Amazon pages I link to should also include their own links for Blu-ray versions of titles, if you prefer that format.
