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. For DVD/Blu-ray releases, I try to find a link for the specific movie or show on the distributor's website; failing that, I'll link to a retailer like Target.com or Amazon.com.
