The following timeline details the events of A Nightmare on Elm Street (film series) in chronological order. In places they are significantly different than the events in A Nightmare on Elm Street (book adaptations of the film series by Bob Italia).
In the 2009 comic book "Freddy vs. Jason vs. Ash: The Nightmare Warriors", Agent Wesley Carter travels back in time. In 1964, then, he signs Freddy Krueger's warrant which has not been done in the timeline established in the movies. This was one reason why Krueger was released from prison and killed by the parents of Elm Street. This event in the comic therefore alters the entire A Nightmare on Elm Street history as we know it. Unfortunately, there is no further information by the authors of the comic about this topic.
Note: According to Jason Goes to Hell: The Final Friday and Freddy vs. Jason (film), the A Nightmare on Elm Street film series and the Friday the 13th film series are a part of the same story. This makes it impossible to exactly determine where one film series ends and the other begins.

December: While working as a nun at the Hathaway House in Springwood under the name in Christ "Sister Mary Helena", Amanda Krueger is accidentally locked in the institute when the building is locked up for the Christmas holidays.

(In A Nightmare on Elm Street 3: Dream Warriors (film), Neil Gordon says the Amanda Krueger scandal occurred in the 1940s. Based on the fact that her son Freddy had a daughter in 1961, it would make sense to allow Freddy's birth to take place as soon as possible.
