This is a main timeline of events in Danny Phantom.
While the series began in 2004 and ended in 2007, time does not seem to progress over those years within the present day of the show. In addition, very few specific years are given or implied in-universe. Therefore, this timeline is not so much a list of dates, but rather an order of events within the show, using generalized ranges and real-life historical years where appropriate, and loosely based on the assumption that it occurs around 2004.
