Timeline



The Timeline of the Young Justice series (which takes place in Earth-16 of the DC Multiverse), is a chronological representation of the show's continuity. Producer Greg Weisman keeps a timeline document that the show's writers and producers use while creating the series. On December 3, 2010, this document was 139 pages long. On January 28, 2011, the document was 149 pages long.

Note: In this timeline the current year of the series is assumed to be 2011, the current year in the real world. During the episode "Schooled", a school photo that reads "2011 Gotham Academy Mathlete Honoree Dick Grayson" can be seen in a trophy cabinet. Many other dates are calculated backwards from this.
